What is the weather like in Portugal in January?

The weather in January in Portugal usually means mild temps and a mix of sunshine and rain. Rainfall averages between 100 and 150 mm this month, depending on the region. It’s usually not constant, but heavier downpours can cause delays if you're out in more rural parts.

Tourism slows down a lot after the vacations, so it’s a quieter time to visit. The weather can swing around—sunny one minute, drizzly the next. If you’re heading over in January, keep an eye on the forecast. It’s a good time for indoor plans. Outdoor stuff like hiking or beach days can be hit or miss depending on the weather.

Average temperatures in January in Portugal

It’s winter here, so temperatures are on the cooler side compared to spring or summer but still relatively mild for Europe. During the day, average highs range from 50°F to 64°F (10°C to 18°C), depending on the region. Nights get colder, dropping to around 41°F to 52°F (5°C to 11°C). Rain is fairly common, especially in the north, and skies can shift quickly between sunshine and clouds.

Sea temperatures hover around 57°F to 61°F (14°C to 16°C), so swimming isn’t ideal unless you're used to cold water or have a wetsuit. Most people stick to land-based activities this time of year. Days are shorter, with around 9 to 10 hours of daylight, so it’s worth planning any outdoor exploring accordingly. 

Porto and northern Portugal

Northern Portugal, including Porto and the surrounding areas, tends to be the coldest part of the country in January. Daytime temperatures usually stay between 50°F and 57°F (10°C to 14°C), and it can dip to the low 40s (5°C to 7°C) at night. Rain is frequent, and fog is pretty common in the mornings, especially further inland. You’ll want to dress in layers and be ready for damp weather. See our guide to how many days you need in Porto. 

Lisbon and central Portugal

Lisbon and the surrounding coastline see some of the mildest weather on the mainland in January. Highs usually fall between 57°F and 63°F (14°C to 17°C), and lows stay around 46°F to 52°F (8°C to 11°C). Rain comes and goes, but there are also plenty of dry, sunny days. It’s still too cold for swimming, but beach walks or sitting at a seaside café are doable with a jacket. The city stays active well into the evening and it's a great time for a Lisbon city break.

The Algarve and southern Portugal

In the Algarve, January is cooler but still fairly mild compared to the rest of the country. Daytime temperatures hover between 59°F and 64°F (15°C to 18°C), with nights around 46°F to 52°F (8°C to 11°C). Rain does show up, but not as much as in other areas. The sea’s chilly—about 60°F (16°C)—so it’s not ideal for swimming, but some locals still brave it, especially surfers.

Is January a good time to visit Portugal?

January isn’t peak season in Portugal, but that can actually work in your favor. It’s the middle of winter, so temperatures are cooler—especially by Portuguese standards—but still fairly mild compared to much of Europe. You’ll likely need a jacket, but you won’t be dealing with snowstorms (unless you head to the mountains), and getting around Portugal is relatively easy.

One of the upsides of visiting in January is the lack of crowds. Big cities like Lisbon and Porto are quieter, and you’ll have more breathing room at popular sights. It’s also a good time to visit Serra da Estrela if you're into skiing or snowboarding. It’s one of the few spots in Portugal where you’ll find snow in winter.

New Year’s Eve is a lively time to be in Lisbon or Porto. Expect fireworks, music, and big outdoor celebrations. Just keep in mind: January can be rainy—especially in the north—and daylight hours are shorter.

What about crowds and costs?

January falls squarely in Portugal’s low season. That means fewer tourists, shorter lines, and more space to enjoy popular sights without feeling rushed. Flights and hotels also tend to be less expensive than in the warmer months, which makes this a good time if you're trying to keep costs down.

The flip side? Some restaurants, stores, or smaller tourist spots—especially in less-visited towns—might reduce their hours or take a break for maintenance. If you’re after slightly warmer weather with longer days but still want to avoid summer crowds, spring or early fall—like May or October—might give you more of a balance.

Where to go in Portugal in January

January in Portugal is a quieter, more laid-back time to explore. Here are some ideas for your trip during this nice month for wandering, eating well, and slowing down after the vacations. For more ideas, check out our guide to the best places to visit in Portugal.

Douro Valley

The Douro Valley in January feels peaceful. The vineyards are dormant, so the hills look more bare, but the scenery is still worth the drive. Roads are quiet, and there’s less pressure to rush, which suits 9-day Portugal trips with time for a slower wine-country stop.

Many wine estates stay open through the winter, and you’ll likely have more time to talk to the staff or owners during tastings. Port wine is still the main draw, but it’s also a good time to try hearty local dishes in riverside towns. Driving through the valley, especially with mist in the morning, can be very lovely. Stop at São Leonardo da Galafura for one of the best views.

Nazaré

Nazaré in January is all about the waves. Praia do Norte becomes one of the most dramatic surf spots in the world this time of year, thanks to the deep underwater canyon just offshore. It channels and amplifies Atlantic swells, sometimes creating waves over 60 feet (20 meters) high. This is when professional big wave surfers head to Nazaré to try and break records—and it draws plenty of spectators too. You can watch from the cliffs or the lighthouse, and the size of the waves is unreal. The town itself is quiet, but still open—local restaurants keep serving fresh seafood, and you’ll find fewer tourists around. Caldeirada, a Portuguese fish stew, is especially good in colder weather.

Serra da Estrela

If you’re looking for snow in Portugal, this is where to go. Serra da Estrela is the highest mountain range in the country, and in January, it usually gets enough snow for skiing and hiking (see our guide to hiking in Portugal). The ski area at Torre is small but works fine for beginners or a short winter break. There are also some nice walking trails through forests and open plateaus—expect frozen lakes and snowy views. The villages around the park are known for traditional stone houses, local cheese, and slow-cooked mountain dishes like chanfana (goat stew). It’s a very different feel from the coast or the cities.

What to do in Portugal in January

Portugal in January feels quieter, slower, and a lot more local. Instead of summer crowds, you’ll find winter festivals, regional food that only shows up this time of year, and a pace that gives you space to take it all in. It’s not beach season, but if you’re up for cooler weather and the occasional rain, there’s a lot to experience that most visitors miss. For more ideas, see our guide to undiscovered Portugal off the tourist trail.

Relax in thermal spas

When it’s cold out, soaking in a hot spring just makes sense—and Portugal has some great ones. Places like Termas de São Pedro do Sul have been around since Roman times and still draw people looking to unwind or treat aches and pains. In Caldas da Rainha, the whole town is centered around thermal waters that once catered to royalty. Over in the Azores, the Furnas Valley is something else—you can bathe in warm, mineral-rich pools while steam rises from the earth all around you. While you’re there, don’t skip the cozido das Furnas, a traditional stew slow-cooked subway using the volcanic heat.

Experience traditional winter celebrations

Even after Christmas, Portugal keeps the celebrations going. January brings Janeiras—a tradition where people sing through the streets or from house to house, keeping old songs and customs alive. In the Algarve, almond trees start blooming early, and you’ll find small festivals toward the end of the month with music, dancing, and almond-based treats. January 6th is Dia de Reis (Day of Kings), when families gather for Bolo Rei, a ring-shaped fruit cake with a little surprise baked inside. This is a great thing to do when on a trip to Portugal with kids.

Feira do Fumeiro in Vinhais

Up in northern Portugal, the small town of Vinhais throws a smoked meat fair every January that’s all about local food traditions. If you like cured meats, this is a good one. You’ll see everything from alheiras (a sausage with Jewish origins) to chouriço and presunto, made with time-tested methods. It’s not just a market—you’ll also see butchery demos, local cooking contests, and live music. 

Plan your trip to Portugal in January

If you're ready to head out this new year, here are a few Portugal travel tips to help you plan your winter trip:

What to pack

January is deep winter in Portugal, especially up north. In places like Porto, it rains a lot and the wind cuts through those narrow streets, so you’ll want a solid waterproof jacket and shoes that can handle puddles. Think layers—wool sweaters, thermal tops, scarves you can throw on or take off depending on whether you’re indoors or out. Down south in the Algarve, it's milder but still cool in the evenings, so pack a light coat. Lisbon’s cobblestones can get slick when wet, so shoes with good grip are smart. If you’re heading out to Sintra or the coast around Cascais, a thermos of something hot isn’t a bad idea

Planning your itinerary

If you’re thinking about a trip to Portugal in January, sometimes it helps to start with a sample Portugal itinerary. It gives you a good idea of how to spend your time and what to expect. Here’s one option to consider:

• Portugal 5 days itinerary: Spend 2 days in Lisbon, checking out neighborhoods like Alfama, Belém, and Baixa. Then, head to Porto for 3 days to explore the Ribeira district, tour wine cellars, and enjoy a scenic Douro River cruise.
• Portugal one week itinerary: Start in the north at Foz do Minho, then visit Nazaré, Caparica near Lisbon, and coastal spots like Galapos and Comporta. Finish your trip at the stunning Algarve beaches.
• Portugal 10 days itinerary: This 10-day guide covers Lagos, Évora, Elvas, Lisbon, Coimbra, Serra da Estrela, Porto, and Peneda-Gerês National Park. It’s a mix of cities, mountains, and coastlines. 

When to book

It’s cooler by the coast, but most attractions stay open and you won’t be waiting in lines.  You can usually book museums, tours, and other indoor stuff pretty last minute. That said, rental cars get picked over—so it’s worth reservation one a couple of weeks in advance. If you’re planning to go to Madeira, New Year’s celebrations often roll into early January, so you’ll want to book ahead for that. Mid-month usually has the lowest prices and feels the most laid-back.

Emergency weather information

January in Portugal can bring winter storms along the coast and snowfall in the northern mountains. It’s a good idea to pack waterproof layers, sturdy shoes, and a phone charger, just in case you get caught in the rain or snow. To stay updated, check the IPMA weather app or website, and tune into local news. The national emergency number is 112, and you can reach Civil Protection at 214 247 100. In coastal areas, it’s worth noting the nearest tsunami evacuation point—these are clearly marked. In the mountains, public buildings often serve as safe spots if needed. After heavy weather, take it slow on mountain roads and avoid walking through flooded areas, which can take time to clear.
