What the weather is actually like in December
Forget the idea of a Lisbon winter. The numbers tell a gentler story: daytime highs hover around 15C, occasionally nudging 17C or 18C on the clear days, and nights settle near 8C. I have eaten lunch outside in shirtsleeves at a sunny Lisbon terrace in mid-December more than once, then needed a jacket within the hour once the light went. The real adjustment is not temperature but daylight. You get only about nine and a half hours of it, with the sun dropping behind the river around quarter past five, so the city does a lot of its living after dark under the Christmas lights.
For how the rest of the country behaves in the same month, my Portugal in December guide widens the lens region by region.
Rain is the genuine variable. December is one of the wetter months in Lisbon, but the Atlantic delivers it in bursts, a sharp shower that soaks the calcada and then clears to blue within the hour, rather than the grey all-day drizzle of a British winter. That polished limestone pavement turns lethal the moment it gets wet, which is the single most useful thing I can tell you about December footwear. Check the IPMA forecast each morning, keep a packable shell in your bag, and treat the showers as breaks for coffee rather than reasons to stay in.
There is also the wind to factor in, the breeze that rolls off the wide Tagus estuary and makes the air feel several degrees cooler than the thermometer claims, especially down on the riverfront and up at the exposed miradouros. It is not a fierce wind, but it is the reason a sunny 15C afternoon at a sheltered Chiado terrace can feel almost chilly the moment you walk out onto the open Praca do Comercio. None of this should put you off; the sun is genuinely warm when it is out, and clear December days here can be dazzling.
It simply means you dress for the shade and the wind, not for the patch of sun you happen to be standing in.
The Christmas lights and where to see them
From the last week of November, the Baixa wears its lights. The grandest stretch is Rua Augusta, the pedestrian spine running up from the river, where the arch and the whole avenue are strung with overhead displays that change theme most years. Walk it after dark and it funnels you toward Praca do Comercio, the great riverfront square, which gets its own light installation and is the single best photograph of Christmas in the city. Avenida da Liberdade, the grand boulevard heading up toward the park, runs a quieter, more elegant scheme along its plane trees that I actually prefer to the busier downtown displays.
The lights are free, they are on every evening through early January, and they are the reason an early sunset stops being a problem. My routine is simple: museums and Belem in the short daylight hours, then the illuminated streets once it goes dark. For viewpoints, the Santa Justa area and the miradouro at Sao Pedro de Alcantara give you the lit downtown laid out below, and the Christmas tree that goes up in Praca do Comercio most years is the landmark every local family photographs at least once. Bring a warm layer for standing still; you cool down fast once you stop walking.
Christmas markets, big and small
Lisbon does not have the dense old-town Christmas market culture of central Europe, so adjust your expectations and you will not be disappointed. The largest event is Wonderland in the Parque Eduardo VII, the long sloping park above Avenida da Liberdade, which runs through most of December with a Ferris wheel, an ice rink, food and craft stalls, and a children's funfair. It is busy, frankly commercial, and genuinely fun after dark with the lights on. Entry to the grounds is usually free, with the rides and rink paid separately, so it works whether you want a full evening or just a wander through.
Beyond Wonderland, the markets are smaller and scattered. Rossio square hosts stalls and a tree, the Campo Pequeno bullring sometimes runs an artisan fair indoors, and design and craft markets pop up in places like the LX Factory and the Principe Real garden on weekends, good for honest Portuguese gifts rather than mass-produced trinkets. If you want the markets as your main reason to travel, central Europe does them better. If you want them as one warm, lit evening inside a broader Lisbon trip, they more than earn their place. Check the city council listings, since dates shift a little each year.
What I would steer you toward over the big commercial fair is the food side of December. The covered markets and the better grocers fill up with the season's specialities: the candied fruit for Bolo Rei, the dried figs and almonds, the boxes of broa cornbread, the salt cod stacked for the Christmas Eve table. Wandering one of these in the run-up to Christmas tells you more about how Lisbon actually celebrates than any stall of fairy lights does.
Pair it with a coffee and a custard tart, watch the locals stocking up for their family dinners, and you get the genuinely festive version of the city rather than the version assembled for visitors.
New Year's Eve and the Praca do Comercio fireworks
New Year's Eve, Passagem de Ano, is the loudest night of the Lisbon December. The main free event is the firework display launched over the Tagus from Praca do Comercio, with a stage and live music in the square through the evening and a countdown to midnight. The fireworks themselves go up just after twelve and reflect off the water, which is the whole point of staging them on the river. The square fills early and tightly, so if you want to be inside it you need to arrive well before midnight and accept the crush. It is free, it is enormous, and the atmosphere is genuinely joyful.
My honest advice is to skip the heart of the square and find a riverbank viewpoint instead. The Cais das Colunas steps just east, the Ribeira das Naus waterfront promenade, or the higher miradouros all give you the display without the crush, and you can actually move afterward. Public transport runs late and extra Metro services usually operate that night, but it is heaving, so build in patience or walk. Restaurants book up weeks ahead for set New Year dinners, often expensive, so reserve early or plan a casual evening with sparkling vinho verde and the crowd on the street, which is what most locals do anyway.
What is open and what is closed
Most of Lisbon stays open in December, which surprises people braced for a shuttered city. The major museums, the castle, Belem, the trams and the trains all run on normal or near-normal schedules through the month. The two days that genuinely change things are December 25 and January 1, when many museums, smaller shops and family-run tascas close entirely, and public transport runs a reduced holiday timetable. December 24 sees an early close across much of the city by late afternoon, because Christmas Eve, not Christmas Day, is the main family meal in Portugal, and everyone is heading home to it.
Plan around those three dates and the rest of the month is easy. The big sights, the Sintra day trip, and the riverfront walks are all fully available, and the queues that swallow an hour in July simply are not there. I would book a restaurant for Christmas Day itself, since the open ones fill fast, and check opening hours for anything specific you have your heart set on around the 24th to the 26th and over New Year. Pharmacies, supermarkets and the tourist-facing cafes stay open in some form throughout, so you will never be stuck for a meal or a coffee.
Eating Lisbon at Christmas: bacalhau, Bolo Rei and chestnuts
The Portuguese Christmas table is built around bacalhau, salt cod, and December is when you taste why this dried fish became a national obsession. The classic Christmas Eve dish is bacalhau cozido, simply boiled cod served with potatoes, cabbage, boiled egg and a generous pour of olive oil, eaten late on the 24th before midnight Mass. It is plainer than the elaborate salt-cod recipes you meet the rest of the year, and that plainness is the tradition. If you are in the city on Christmas Eve, a restaurant serving the cozido is the most authentic meal you can find, far more so than anything labelled festive for tourists.
The sweet side belongs to Bolo Rei, the king cake, a ring of light dough studded with candied fruit and nuts, dusted with sugar and sold in every bakery and supermarket from December into January. Traditionally a dried fava bean was baked inside, and whoever found it bought next year's cake; most commercial ones now skip the bean for safety. Buy a slice with coffee and you have the taste of the season in one bite.
There is a plainer cousin, Bolo Rainha, the queen cake, that swaps the candied fruit for nuts if the glace cherries are not to your taste, and most good pastry shops sell both side by side through the month.
And everywhere in the cold weeks, the street braziers appear, selling castanhas assadas, roasted chestnuts in paper cones, the smell of which is, to me, the actual smell of December in this city. You find the sellers on the corners of the Baixa, near the squares and outside the Metro entrances, smoke rising off the coals in the early dark. They are cheap, they warm your hands as much as your stomach, and they are the most authentically seasonal street food going.
Round it out with the festive sweets that appear alongside the Bolo Rei, the fried filhoses, the rabanadas that resemble French toast, and the sonhos, little fried dough puffs, and you have eaten your way through a Lisbon Christmas properly.
Why December hotel prices make this the smart season
The strongest practical argument for December is money. Lisbon accommodation in December, with the clear exception of the few nights around New Year, runs well below the July and August peak, often a third to a half less for the same central apartment or hotel room. The same Baixa or Chiado base that commands premium summer rates becomes genuinely affordable, which means you can stay more centrally than your budget would otherwise allow and walk home tired rather than commuting from the edge of town. If you are weighing Lisbon against a pricier winter-sun rival, the value gap is real and worth doing the maths on.
It is not only hotels. Flights into Humberto Delgado outside the holiday week are softer, restaurant tables are easy to get without booking, and the attractions that bottleneck in summer flow freely. The trade you are making is daylight and a degree of weather risk for cost, space and calm. For a couple, a solo trip, or anyone who has done Lisbon in high season and found it crowded, that trade is overwhelmingly worth it. Block out the New Year nights, when prices spike and minimum-stay rules appear, and the rest of the month is one of the best-value city breaks in Western Europe.
What to pack for Lisbon in December
Pack for layers, not for cold. The winning kit is a long-sleeved base, a warm mid-layer or light fleece, and a properly waterproof shell that packs down into your daypack, because the weather swings from sunny-terrace warm at noon to jacket-cool by six within a single afternoon. You will be peeling layers on and off all day. A scarf earns its place for the evenings, and gloves are overkill at sea level but welcome if you are heading up to Sintra, which sits higher and several degrees colder than the city. Leave the heavy winter coat at home; you will carry it more than you wear it.
Footwear is where Lisbon punishes the unprepared. The calcada portuguesa, that beautiful polished limestone mosaic pavement, turns into an ice rink the moment a December shower passes, and the hills are steep. Bring shoes with real grip and a proper tread; smooth soles, heels and fashion trainers will betray you on the first wet slope. A compact umbrella is useful but the wind off the Tagus turns big ones inside out, so a hooded shell is the more reliable bet. Add sunglasses, because the low winter sun is dazzling, and you are properly equipped for the month.
A short December itinerary that works around the dark
Because daylight is short, I plan December days around the light rather than around a list. Mornings go to the outdoor and the far-flung: Belem and the Jeronimos cloister, the castle terrace, a Sintra day trip on the train if the forecast is kind, all done while the sun is up. The wettest, darkest afternoons go to indoor sights, the Gulbenkian collection, the tile museum, the Time Out Market for a long grazing lunch, so that a passing shower costs you nothing. Then, as the sun drops behind the river, the city's whole character shifts to the lit streets and you simply step outside into it.
Evenings are the December reward. The illuminated Baixa, a fado house with the heating on and the room close and warm, a glass of red and a plate of grilled chestnuts. If you have three days, lean on my three days in Lisbon plan and just shift the outdoor parts to the mornings and the museums to the rain. The pace is naturally slower than summer, which suits the season. You are not racing the heat or the crowds now; you are following the light while it lasts and then enjoying the long, lit evenings that are the real gift of Lisbon in December.
Is Lisbon in December actually worth it?
For most travellers, yes, with clear eyes about what you are getting. You trade the long beach-warm days of summer for short daylight and the chance of rain, and in return you get a mild, decorated, half-empty city at a fraction of the cost, with the locals visibly relaxing into their own festive season rather than serving a tourist peak. If your dream of Lisbon is sunbathing and long golden evenings on a rooftop, December is not your month and you should aim for May or September instead. If your dream is the city itself, lived slowly, December is quietly one of the best times to come.
It suits some travellers more than others. It is excellent for couples, for solo trips, for anyone who has been put off by summer crowds, and for the festive atmosphere without the deep cold of a northern Christmas. It is harder for a pure beach holiday or for travellers who cannot tolerate any weather risk in their planning. My own verdict, after more than a decade of Decembers here, is that the month shows you a truer Lisbon than July ever will, a working city in its own celebration, and that the savings on top are simply a bonus on a trip already worth taking.
Why it matters
Why it matters: most people picture Lisbon as a summer city and write off the winter without checking the numbers. December is genuinely mild, with highs near 15C and almost no frost, and the city is decorated, calmer and far cheaper than in July. Travellers who understand the real trade, short daylight and some rain in exchange for low prices and small crowds, can plan a trip that plays to the season rather than against it. Knowing what closes on the 25th, what the fireworks involve, and how to dress for swing-temperature days turns a gamble into one of the best-value breaks in Western Europe.
Practical tips
- Pack layers and a packable waterproof shell rather than a heavy coat; afternoons can feel warm and evenings turn cool fast.
- Bring shoes with real grip, because Lisbon's polished calcada pavement becomes dangerously slippery after the frequent December showers.
- Plan outdoor sights and day trips for the short daylight hours and save museums and markets for the wettest afternoons.
- Book a restaurant in advance for Christmas Day and for New Year's Eve, when the open ones fill quickly and many close entirely.
- Watch the Praca do Comercio fireworks from the Ribeira das Naus waterfront or a miradouro to skip the crush inside the square.
Local insight
Local insight: my December rule is to let the early sunset reorganise the day instead of fighting it. I treat the daylight hours as precious and outdoor, the castle, Belem, the river, and I treat the long evenings as the main event, lit streets and a warm fado room rather than dinner-and-bed. Visitors who keep trying to run a summer schedule end up frustrated by the 5.15pm dark. The ones who flip it, doing their walking in the light and their celebrating after it, get the version of December that makes me happy to live here through every one of them.

Frequently Asked Questions
How cold does Lisbon get in December?
Lisbon stays mild in December by European standards. Daytime highs average around 15C and can reach 17C or 18C on clear days, while nights drop to roughly 8C. Frost is almost unheard of at sea level, and snow effectively never falls in the city. The cold you actually feel is less about the temperature and more about the short daylight and the wind off the Tagus once the sun goes down. Dress in layers, keep a warm layer for the evenings, and you will be comfortable through the whole month.
Does it rain a lot in Lisbon in December?
December is one of Lisbon's wetter months, so you should expect some rain, but it usually arrives in short, sharp Atlantic showers rather than all-day downpours. A typical pattern is a soaking burst that clears to blue sky within the hour. The practical response is to carry a packable waterproof shell, check the IPMA forecast each morning, and keep flexible plans so a passing shower simply becomes a coffee break. The bigger hazard than the rain itself is the slippery limestone pavement it leaves behind, so grippy shoes matter.
Are the Christmas lights worth seeing in Lisbon?
Yes, and they are free. From late November into early January the Baixa, Rua Augusta and Praca do Comercio are strung with overhead light displays, and Avenida da Liberdade runs a quieter, more elegant scheme along its trees. Because the sun sets around 5.15pm in late December, the lit streets become the natural focus of the evening rather than an afterthought. Walk Rua Augusta down to the illuminated riverfront square for the best of it, and bring a warm layer, since you cool down quickly once you stop walking to look.
What happens in Lisbon on New Year's Eve?
The headline event is a free fireworks display launched over the Tagus from Praca do Comercio just after midnight, with live music and a countdown in the square through the evening. The square fills tightly, so arrive early if you want to be inside it, or watch from the Ribeira das Naus waterfront or a higher viewpoint to avoid the crush. Extra late-night Metro services usually run but are packed. Restaurants book up weeks ahead for set New Year dinners, so reserve early or plan a casual street celebration with the crowd instead.
What is open in Lisbon over Christmas?
Most of the city operates normally through December, including museums, the castle, Belem and public transport. The exceptions are December 25 and January 1, when many museums, shops and family-run restaurants close and transport runs a reduced holiday timetable. December 24 sees an early close across the city by late afternoon, because Christmas Eve is the main family meal in Portugal. Plan around those three dates, book a restaurant for Christmas Day itself, and the rest of the month is fully open and far quieter than summer.
What food should I try in Lisbon at Christmas?
Start with bacalhau cozido, the simply boiled salt cod with potatoes, cabbage and egg that is the traditional Christmas Eve dish, eaten late on the 24th. For something sweet, Bolo Rei is the king cake of the season, a ring of light dough studded with candied fruit and nuts, sold in every bakery from December into January. And all through the cold weeks, street braziers sell castanhas assadas, roasted chestnuts in paper cones, whose smell is the essence of Lisbon in December. Pair any of it with a coffee or a glass of red.
Is December a good time to visit Lisbon?
For most travellers, yes. You trade short daylight, about nine and a half hours, and some weather risk for a mild, decorated, half-empty city at well below summer prices. Hotels outside the New Year week often cost a third to a half less than in July, queues vanish, and the festive atmosphere is genuine. It is ideal for couples, solo trips and anyone put off by summer crowds, and less suited to a pure beach holiday. If you want the city itself rather than the sun, December is quietly one of the best times to come.
