When choosing the best time to visit Portugal, weather matters. Good weather makes it easier to explore the cobblestone roads that weave through cities in Portugal and to enjoy the coast or islands, while the off-season can offer a more relaxed feel with fewer crowds.
This guide shares practical advice from Sandra C., a seasoned traveller who is from Portugal, currently living in Lisbon. She has been leading tour design at Collette for Portugal since 2022.
Quick Answer: When’s the Best Time to Visit Portugal?
Spring (March–May): The best time of year for walking and sightseeing in cities. The weather in May is a nice “sweet spot,” offering longer days without the heat of summer.
Summer (June–August): Summer is best for the coast (especially the Algarve). Inland touring and walking cities still work, but you’ll want to pace yourself with breaks throughout the day because it gets very hot.
Fall (September–November): Late fall is a great season to enjoy Portugal on foot — a must in many cities. October is good for tours across multiple regions.
Winter (December–February): Winter weather in Portugal is generally mild compared to northern Europe. You’ll want to plan (and pack) for more rain than bitterly cold weather and be mindful that you’ll have fewer daylight hours to explore. If you prefer off-season travel with fewer crowds, December in Portugal can be a good choice.
Islands: Weather in the Azores is changeable and requires flexibility around internal flights, while weather in Madeira is mild throughout the year.
Best Time to Visit Portugal Based on What You Like to Do
The best season for you depends on what you plan to do on your trip to Portugal. For most travellers and many of our tours, that means exploring on foot. Some places are difficult to access by vehicle and travellers will have a more immersive experience walking through neighborhoods and strolling through the postcard views.
Sandra is especially direct about two realities travellers should consider when planning their trip or choosing a guided tour to Portugal:
Cities require walking. Lisbon tours include cobblestone streets and lots of walking, and Porto’s historic centre is steep with strict access limits for buses and vans. On the plus side, you’ll get your steps in, so you can fully enjoy Portugal’s food and drinks.
Pacing matters. Because Portugal is best explored on foot, Collette offers tours with longer stays (like multiple nights in the Algarve) that give you time to rest after active days — or explore more on your own. Our tour guides are always happy to suggest things to do in Portugal.
Best Season to Visit Portugal for Walking and Sightseeing
Spring and fall are usually the best seasons for trips that centre on Lisbon, Porto, and historic towns. The moderate weather makes walking over cobblestone and up hills for those amazing views much more enjoyable.
May is a top choice for travellers who want full days to immerse themselves in Portugal’s cities, countryside, and coast — without peak heat. October delivers the same kind of shoulder-season advantage: good weather, walking and outdoor activities, with less of a peak-season feel.
If your trip includes Porto, this shoulder-season logic becomes even more useful. Sandra explains that Porto’s historic centre is compact and steep, and that strict vehicle restrictions mean comfortable walking conditions matter.

Best Season to Visit Portugal for Fewer Crowds and a Relaxed Pace
If you enjoy a calmer pace and lighter crowds, winter travel in Portugal can be a smart choice with a more relaxed atmosphere and potential discounts. With milder winter weather, Portugal doesn’t get the deep cold seen in northern countries, but you will need to plan for rainy days and fewer daylight hours.
Pack sturdy footwear to keep your feet dry and safe on wet cobblestones, and plan on more indoor activities like museums, food markets, and historic centres.
Best Time to Visit the Azores or Madeira
Portugal’s islands follow their own weather patterns, with mild weather year-round in Madeira and less predictable weather in the Azores.
In the Azores, lush greenery is the result of frequent rain. This rain and wind can affect internal flight schedules. A little flexibility is a must, and well worth it. We run our Azores tours April through October, with late spring into summer offering the best combination of weather and seasonal highlights like all those beautiful hydrangeas.
Spring Weather in Portugal (March, April, May)
Spring is one of the most practical seasons for travellers who want full sightseeing days without peak heat. If your plans include Lisbon, Porto, Sintra, or historic towns, spring weather is perfect for walking around neighborhoods, exploring old quarters, and spending time outside.
Spring is also a good season if you plan to visit multiple regions. For example, our Sunny Portugal tours include Lisbon, inland Alentejo, and the Algarve. And if island travel is part of your plan, late spring in the Azores is a great time for nature lovers.
Summer Weather in Portugal (June, July, August)
Summer months can be fantastic — especially when you include the coast where you can catch a break from peak summer heat.
That’s why Sandra includes multi-night stays in the Algarve on many of Collette’s Portugal tours. Including some coastal time gives travellers a chance to breathe with relaxed mornings and more time to explore at their own pace. It’s also a great way to reset and relax after busier days walking through cities.
Fall Weather in Portugal (September, October, November)
Fall strikes a good balance for travellers who want the advantages of summer warmth without peak-season pressure. The off-season offers a different experience at major sites and makes cities easier to enjoy, making it a good time for multi-city tours.
Winter Weather in Portugal (December, January, February)
Winter months in Portugal often have milder temperatures than travellers expect. Rain and shorter days are still worth keeping in mind when packing and choosing things to do. Sandra notes that December can be a good month, especially if you enjoy holiday lights.
