What is the weather like in Portugal in October?

October in Portugal marks the shift into fall. The weather is generally mild, but you’ll start to notice cooler temperatures and a higher chance of rain, especially as the month goes on.

It’s still a good time for hiking and sightseeing, but you’ll want to check the forecast before heading out (see our guide to hiking in Portugal). Pack a light jacket and an umbrella. Portugal sees anywhere from 60 to 100mm of rain during October, depending on the region. If you're heading up north, expect wetter conditions than in the south.
If you’re looking for a time with fewer people around, October can be a good time to visit. The weather is still pretty pleasant but is pretty different from the summer.

What about crowds and costs?

October falls during Portugal’s shoulder season, so things start to slow down after the busy summer months. You’ll still run into some tourists—especially in popular spots or during weekends—but it’s generally quieter. It’s a good time to visit if you prefer a bit more space without everything feeling completely empty and getting around Portugal during this month is relatively easy.

Prices for things like hotels, transport, and activities usually dip compared to summer. You might come across some deals, especially on accommodation, as places try to fill their remaining availability before winter kicks in.

If you’re really looking to avoid crowds and don’t mind cooler, rainier weather, you could also think about visiting in November or February. Those months tend to be a little cheaper, but you’ll want to pack more layers and plan around the weather a bit more carefully.

Average temperatures in October

October in Portugal brings cooler weather and the start of the rainy season, but it’s still a comfortable time to be outside. Daytime highs usually range from 64°F (18°C) to 73°F (23°C), while nights can dip to around 52°F (11°C) to 61°F (16°C). Compared to the hotter, drier summer months, October feels milder and a bit more unpredictable—sunny spells mixed with cloudy days and the occasional shower.

The Atlantic is starting to cool, but sea temperatures typically sit around 66°F (19°C) to 70°F (21°C), which some people still find fine for a swim—especially earlier in the month or in the south. Portugal sees about 11 hours of daylight in October, so there’s still time to get out and explore before it gets dark.

Porto and northern Portugal

In the north, including Porto, October tends to be cooler and wetter than other regions. Highs are usually between 64°F (18°C) and 68°F (20°C), with lows around 54°F (12°C) to 57°F (14°C). Rain becomes more frequent, so you’ll want to pack for wet weather if you’re spending time outside. Sea temperatures around Porto average 66°F (19°C), which might feel too chilly for swimming, but it’s still a good month for city walks and day trips if you're dressed for the conditions. See our guide to how many days you need in Porto. 

 Lisbon and central Portugal

Lisbon and central Portugal stay relatively mild in October, with daytime temperatures around 70°F (21°C) to 73°F (23°C) and nights cooling to between 57°F (14°C) and 61°F (16°C). The city stays active well into the evening and it's a great time for a Lisbon city break. Rain starts to show up more often, but there are still plenty of dry days. The sea here is around 68°F (20°C) to 70°F (21°C), so you might still get a swim in, especially at the start of the month. It’s a good time to visit if you’re after fewer crowds.

The Algarve and southern Portugal

Southern Portugal, including the Algarve, tends to hang on to the warmth a bit longer. You can expect daytime highs between 73°F (23°C) and 77°F (25°C), and nighttime temperatures between 61°F (16°C) and 64°F (18°C). There’s a slight uptick in rain, but most days are still good for being outside. The sea stays around 70°F (21°C), which is still decent for swimming if you’re used to cooler water. 

Madiera

Madeira in October feels warm and humid, with more rain than in the summer but still plenty of chances to enjoy the outdoors. Daytime temperatures usually reach 73°F (23°C) to 77°F (25°C), while nights stay around 64°F (18°C) to 68°F (20°C). The sea is still comfortable at around 73°F (23°C), so swimming and boat trips are still in the picture. Rain comes in short bursts, so it’s worth packing a light waterproof layer.

Where to go in Portugal in October

The weather in Portugal in October is still decent in most parts of the country, but things have calmed down. It’s also harvest season in a lot of areas, which adds something extra to road trips and rural getaways. Here are our picks for this month. For more ideas, see our guide to the best places to visit in Portugal.

Algarve

The Algarve slows down a bit in October, in a good way. It’s still warm enough to swim, and the sea hasn’t cooled down too much yet. It’s a calmer time along the coast, so you’ll likely find open space on the sand and a quieter atmosphere in the towns. If you’re planning on hiking, the cliffside trails are much easier to manage without the heat. It’s also a good time to check out smaller beach coves that are usually packed in summer. Be sure to grab a seat at one of the seafood places near the water. This is a great base for a trip to Portugal with kids.

Douro Valley

This is harvest time in the Douro Valley, so things are busy in the vineyards.  If you’re into wine, or even just curious, it’s a good chance to see how things work at the local estates. Many of them have seasonal events or let you stop by for a visit, and some places still do grape stomping by foot, which you can sometimes take part in. The hillsides turn all kinds of golds and reds.

Santarém

In October, Santarém hosts the National Gastronomy Festival, which is one of the best reasons to visit.  It’s a small, historic city in central Portugal, and during the festival, the focus turns to food and seasonal ingredients. You’ll find tastings, demonstrations, and market stalls with local products. The countryside around the city is also in the middle of harvest season, so it’s a good time to visit nearby farms or vineyards. It’s a nice time of year to walk around the old town. You’ll come across Gothic churches and older buildings that are worth a look and that are easy to see in a day or two.

What to do in Portugal in October

October is a great month to experience Portugal at a slower, more grounded pace. The weather’s cooler but still comfortable, and there’s a noticeable shift in energy as locals ease into fall. It’s a good time to get into seasonal food, spend time outdoors, and take part in traditions that aren’t always front and center during the summer rush.  For more ideas, see our guide to undiscovered Portugal off the tourist trail.

Cork harvesting

If you’re in the Alentejo, this is one of the few times you might actually get to see cork being harvested. The region’s full of cork oak trees, and some farms let you come by and watch how it’s done. Workers use simple tools and careful techniques to peel the bark by hand—no machines, just skill passed down over time. It’s part of a cycle that only happens every nine years, so seeing it in person gives you a real sense of how long this process takes. You’ll also learn what cork is used for beyond wine bottles—things like bags, flooring, and insulation. It’s an old practice but still very present in everyday life here.

Birdwatching

Down in Sagres, on the Algarve coast, October is peak bird migration season. There’s a birdwatching festival this time of year where you can join walks, talks, and boat trips to spot species as they pass through on their way south. You don’t have to be a bird expert—just bring some curiosity and maybe a pair of binoculars. This part of Portugal is one of the last stopovers before birds cross into Africa, so the skies can get pretty busy. The landscape—cliffs, beaches, and open skies—makes the whole thing feel peaceful, even when you’re surrounded by other watchers.

The Festival da Francesinha

In Porto, this month usually brings the Francesinha Festival. If you’ve never had one, the francesinha is a layered sandwich packed with meat and cheese, then topped with a beer and tomato sauce. It’s the kind of dish that inspires strong opinions—everyone swears their favorite spot does it best. During the festival, restaurants around the city get a little more playful with their recipes. You can try a few versions, see what you like, and enjoy some live music or performances while you’re at it. 

Plan your trip to Portugal in October

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

What to pack

October starts to feel like fall, especially in the north. Layering is smart—be sure to bring long-sleeve shirts, light sweaters, and a water-resistant jacket. The Algarve still gets decent warmth during the day, but you’ll want something for the evenings. If you’re walking around cities like Braga or Guimarães, wear shoes with decent grip—cobblestones get slick when it rains. A small umbrella and a day bag that can handle some rain make city days easier. You might still get some beach time in the south, but it’s a good idea to bring something warm to throw on afterward. For hikes or nature trips in places like Peneda-Gerês or Serra da Arrábida, go for lightweight hiking gear 

Planning your itinerary

If you’re traveling to Portugal in October, checking out a sample Portugal itinerary can make your planning easier. Here’s a few to get you started: 

• Itinerary 5 days in Portugal: Spend 2 days in Lisbon, then head to Porto for 3 days to explore Ribeira, tour wine cellars, and enjoy a relaxing Douro River cruise.
• Itinerary 7 days in Portugal: From Foz do Minho to Nazaré, Caparica, Galapos, Comporta, and the Algarve beaches, you’ll cover a lot of great coastal spots.
• Itinerary 10 days in Portugal: A 10-day route through Lagos, Évora, Elvas, Lisbon, Coimbra, Serra da Estrela, Porto, and Peneda-Gerês National Park.

When to book

You might need to book tickets in advance for big events in October, but otherwise things are pretty relaxed. If you’re heading north, the Douro Valley looks amazing with the fall colors—and early in the month, you can still catch some harvest activity. Madeira also stays warm with fewer crowds. You don’t need to book far ahead—4–6 weeks is usually enough for nicer places. Car rentals also drop in price, but if you’re picky about what you drive, it’s still smart to book early.

Emergency weather information

October tends to bring more wind and rain, especially along the coast. Pack a windproof jacket and consider a waterproof phone case. If you’re staying near the ocean, it’s worth keeping up with IPMA storm alerts or tuning in to Radio Cascais (93.8 FM), which has English updates. If needed, emergency services are at 112, and coastal assistance is available at 210 911 162. Community spaces like schools or sports centers may be used as local shelters during stormy weather. After a storm, be aware of debris on roads and possible power outages.
