What is the weather like in Portugal in December?

December in Portugal usually brings cooler temperatures, shorter days, and a decent chance of rain—especially up north. It’s the start of winter, so expect things to feel a bit more damp and chilly compared to the warmer month though getting around Portugal during this month is relatively easy.

Tourism tends to slow down this time of year, which means fewer crowds and lower prices. At the same time, you’ll still catch plenty of local charm. Cities and towns light up for the vacations, with Christmas markets, decorations, and seasonal events adding a festive touch.

If you're hoping to spend time outdoors, it’s worth keeping an eye on the forecast. Rain is more frequent in December—especially in the north, where averages can reach 150mm—so hiking or beach days might be hit or miss. That said, indoor activities like checking out museums, cozy cafés, or historic sites are still very doable. December can be a relaxed time to visit Portugal—just bring some layers and a good umbrella, and you’ll be set.
 

Average temperatures in December

Portugal in December is in the early part of winter, with mild to cool weather depending on where you are. Daytime temperatures usually sit between 50°F and 64°F, while nights can drop to 39°F to 50°F. Compared to the hotter summer months, this is a cooler and wetter time of year, but still relatively mild for Europe. Rain is more frequent now, especially in the north, though you’ll still get some clear, crisp days.

Sea temperatures hover around 61°F to 63°F, which can feel chilly for swimming unless you're used to colder water or wearing a wetsuit. Most people stick to walking along the beach rather than getting in.

Days are short in December, with about 9 to 10 hours of daylight depending on the region.

Porto and northern Portugal

Northern Portugal, including Porto, tends to be the coolest and wettest part of the country in December. Daytime highs usually sit around 52°F to 55°F (11°C to 13°C), with nighttime lows dropping to 41°F to 45°F (5°C to 7°C). Rain is fairly regular this time of year, and overcast days are common. It's a good time for indoor activities (maybe spending time at wine cellars, bookstores, and cozy restaurants) since the weather outside can be unpredictable. Snow is rare in the cities but more common in the nearby mountains. See our guide to how many days you need in Porto. 

Lisbon and central Portugal

In Lisbon and the surrounding central areas, December feels milder. Highs during the day usually reach between 59°F to 63°F (15°C to 17°C), while nighttime temperatures stay around 46°F to 50°F (8°C to 10°C). Rain does come and go, but it’s often in short bursts rather than all-day downpours. The climate is still comfortable enough for walking tours, outdoor cafés, and even some sunny afternoons by the water.  The city stays active well into the evening and it's a great time for a Lisbon city break.  While you won’t see beach crowds like in summer, the Atlantic can still draw surfers—though swimmers may find the water too cold. 

The Algarve and southern Portugal

Southern Portugal, including the Algarve, stays relatively warm in December. Daytime highs hover between 61°F to 64°F (16°C to 18°C), and nights usually don’t fall below 48°F to 52°F (9°C to 11°C). You’ll still get rain here, but generally less than in the north. The region is quieter in winter, and it’s a great time for hiking trails (see our guide to hiking in Portugal). While the sea is around 62°F (17°C)—too cold for most casual swimmers—it’s still pleasant enough to spend time by the water or enjoy lunch outside on a sunny day. The Algarve stays bright and fairly dry.

Madeira

Madeira stays mild in December thanks to its subtropical climate. You can expect daytime highs between 66°F to 70°F (19°C to 21°C), with nighttime temperatures staying around 59°F to 63°F (15°C to 17°C). Rain does show up occasionally, but it usually comes and goes quickly. The island feels comfortable overall, with more warmth than mainland Portugal this time of year. 
 

Is December a good time to visit Portugal?

December isn’t peak travel season, but it has its own appeal—especially if you’re not chasing beach days. As winter sets in, you’ll get cooler temperatures and a higher chance of rain, but compared to much of Europe, the weather is still relatively mild, particularly along the coast (like in Lisbon or Porto).

The vacations are a nice bonus. Streets light up, Christmas markets pop up in city squares, and you’ll catch the smell of roasted chestnuts as you wander around. It's not swimming weather, but the beaches are still great for peaceful walks and sea views without the crowds.
Just make sure to pack layers and a waterproof jacket, and plan a mix of indoor and outdoor activities in case the weather shifts. It’s a slower time of year, which means you get to take things at a more relaxed pace.

What about crowds and costs?

December is low season in Portugal, so things tend to feel a bit quieter. Popular sights are still open, but without the long lines and packed viewpoints you’ll find in summer. Cities take on a slower rhythm, which can be a nice change if you're looking to avoid the rush.
It’s also a good month for saving money. With fewer tourists around, accommodation and transportation often come at lower rates. Some places run winter deals, and it’s easier to find availability on shorter notice.

That said, a few downsides are worth noting. Some tourist attractions—especially in smaller towns—might have shorter hours or be closed altogether around the vacations. It’s smart to double-check ahead before making specific plans.

If you’re hoping for similar crowd levels but slightly better weather, you might want to look at March or October instead. Those months tend to be warmer but still fly under the radar. 
 

Where to go in Portugal in December

Portugal in December can be a nice break from colder winter weather elsewhere. City breaks work well, especially in the south, and there are lights and low-key festive events across the country. Here’s our pick for December. For more ideas, take a look at our guide to the best places to visit in Portugal.

Lisbon

Lisbon takes on a laid-back, festive vibe in December. Avenida da Liberdade is lit up with Christmas lights, and you’ll find big displays in Praça do Comércio and Rossio Square—lots of maritime-themed decorations. Wonderland Lisboa sets up in Eduardo VII Park with an ice rink and market stalls. If it rains, which it sometimes does, head into the older neighborhoods like Alfama or Baixa. You’ll find here plenty of cozy tascas where you can warm up with a plate of bacalhau and a small glass of ginjinha.

Madeira Island

Madeira’s climate stays pretty mild year-round, and December is no exception.  Funchal starts to light up for the vacations, and if you’re there at the end of the month, New Year’s Eve is a big event with a fantastic firework display. 
Earlier in December, you can check out the Mercado dos Lavradores for seasonal fruit, flowers, and candy. The levada walks are easier to manage this time of year, without the summer heat or foot traffic. Even in winter, the island stays lush, so it still feels like a break from mainland weather.

Óbidos Vila Natal

Óbidos is a small medieval town that leans into the vacation season. The medieval town turns into a Christmas-themed spot with skating, market stalls, lights, and fairground rides. You’ll smell roasted chestnuts as you walk through, and people line up for ginjinha served in chocolate cups. t’s a popular outing for families, but it’s also a nice spot for anyone looking for a quiet, festive day trip. The old streets and castle walls feel especially atmospheric this time of year—just wear good shoes and dress for the cooler weather.
 

What to do in Portugal in December

Portugal in December has a slower pace that makes it easy to enjoy the day-to-day. You won’t be elbowing through crowds, and the cooler weather is a nice change if you’re used to heat or humidity. This time of year feels more local—families gathering for vacation meals, small-town celebrations, and traditional foods you mostly see in winter. You’re likely to spot bolo rei in every bakery window (it’s a fruit-studded cake that shows up around Christmas), plus filhós and rabanadas—both fried, sweet, and eaten in generous amounts.  For more ideas, see our guide to undiscovered Portugal off the tourist trail.

Explore Christmas markets (Mercados de Natal)

In December, most cities and towns set up Christmas markets, known as Mercados de Natal. These are usually in central squares and draw a mix of locals and visitors looking for gifts, snacks, or just something warm to drink. Lisbon’s Campo Pequeno has a big indoor market with local crafts and food stalls, while Vila Real de Santo António in the Algarve has a smaller setup that still feels festive. You’ll find things like handmade ceramics, wool socks, regional candy, and mulled drinks—some with alcohol, some without. This is a great thing to do when on a trip to Portugal with kids.

Attend a fado performance

Fado makes more sense in winter. The music is emotional and a little heavy, and December nights add to that mood. You’ll find traditional fado houses in Lisbon’s Alfama and Bairro Alto neighborhoods. These are usually small spots with dinner service, where the lights go down and people actually stay quiet while the music’s playing. Coimbra has its own version of fado too, tied to the university there—it’s a bit different in tone, but still intimate

Relax in thermal baths

When it’s cold out, a hot soak hits the spot. Portugal has a handful of towns with natural thermal springs that have been used for centuries—some since Roman times. São Pedro do Sul, Caldas da Rainha, and Chaves are three of the more well-known ones. The water stays warm year-round, around 95–104°F (35–40°C), and many bathhouses also have massage services or other treatments if you want to turn it into more of a full-on spa day. The towns themselves tend to be calm and a bit old-fashioned, with local restaurants and cafés where you can grab a meal before or after.
 

Planning your trip to Portugal in December

Some Portugal travel tips to help you plan your winter trip:

What to pack

You’ll want to bring warm layers—sweaters, scarves, gloves, and a waterproof jacket that can handle wind and rain. In the north, cities like Bragança or Vila Real can get close to freezing, so be prepared for actual winter weather. Even Lisbon and Porto need warm clothing this time of year. Down south, the Algarve stays milder, but evenings still get cold, so a proper coat helps. Waterproof shoes with good grip are useful across the board—rain is more frequent, and sidewalks can get slick. If you’re heading to vacation events or dinners, pack something a little nicer that still layers easily. A small, foldable shopping bag is helpful if you’re planning to browse Christmas markets or pick up local treats and gifts.

Planning your itinerary

If you’re planning a trip to Portugal in November, a sample itinerary is a great place to start to make sure you make the most of your trip. Here are some of our favorite Portugal itineraries:

• 5-day Portugal itinerary: Spend 2 days in Lisbon, visiting Alfama, Belém, and Baixa. Then, head to Porto for 3 days to explore Ribeira, visit wine cellars, and enjoy a scenic river cruise.
• 7-day Portugal itinerary: From Foz do Minho to Nazaré, Caparica, Galapos, Comporta, and the Algarve beaches, you’ll get a great mix of coastlines.
• 10-day Portugal itinerary: A 10-day journey through Lagos, Évora, Elvas, Lisbon, Coimbra, Serra da Estrela, Porto, and Peneda-Gerês National Park gives you the full picture of Portugal.

When to book

December is a bit of a mix. The first half of the month is quiet and affordable, and you’ll find good deals on accommodation. Once the vacations kick in, though, prices jump—especially around Christmas and New Year’s. 

For Christmas week (Dec 22–Jan 2), book 4–5 months ahead no matter where you’re going. Earlier in the month, you don’t need much advance planning. If you want a festive atmosphere without the high prices, consider smaller historic towns like Évora or Coimbra
Madeira is the exception here—its New Year’s celebration is world-famous, so it gets busy and expensive. If you’re heading there, book 6+ months out. 

Emergency weather information

In December, Portugal sees more winter weather—coastal storms, some flooding, and the chance of snow in the mountains. Thermal layers and waterproof outerwear will help keep you warm and dry. It’s worth following IPMA or Civil Protection Authority social media for current conditions. If you’re driving, save the road assistance number: 308 811 333. In bad weather, places like hotels, shopping malls, and public buildings such as libraries are good spots to wait things out. After a storm, watch for icy roads or fallen branches, especially in the north.
