Portugal in October: Where to Go, What to Do, the Weather, & More

October is among the best months to visit Portugal due to comfortable temperatures and lower tourist crowds than in summer. Daytime highs average around 70°F across most of the country, with cooler evenings dipping into the 50s, making the weather ideal for sightseeing. Rain increases as autumn progresses, but the first half of October is relatively dry before the wetter winter pattern sets in. Pack layers to adjust to shifting conditions throughout your trip.

While not cold by winter standards, October ushers in cooler temperatures across Portugal as summer gives way to fall. Average highs range from the mid-60s Fahrenheit in the north to the low 70s down south. Nighttime lows dip into the 50s, so having a warm layer or light jacket is advisable, especially for evenings out. The interior regions tend to be slightly chillier than coastal areas moderated by the Atlantic Ocean.

Lisbon • Best Place for Sightseeing

Lisbon, Portugal’s capital, offers an unparalleled blend of history, culture, and scenic beauty for you to explore, with October a great time to take it all in as the weather is mild. Visit the medieval maze of Alfama, the city's oldest neighborhood, or take in sweeping vistas from the landmark Castelo de São Jorge in pleasant conditions. Without the sweltering heat of summer, you can comfortably experience Lisbon's charms on foot or by tram in October, whether squares like Praça do Comércio, which showcases Lisbon's grand architecture, or the artistic treasures of world-class museums like the Calouste Gulbenkian.

Algarve • Best Place for Great Weather

Situated in southern Portugal along the Atlantic coast, the Algarve region boasts some of the country's warmest and sunniest weather in October. While the rest of Portugal cools down, highs in the Algarve still reach the mid-70s Fahrenheit on average. Sea breezes take just enough of an edge off to create ideal conditions for you to lounge on the famous beaches, golf on championship courses, or explore charming coastal towns like Lagos and Tavira before winter arrives.

Porto • Best Place for Families with Children

Porto makes an excellent family destination in October. The mild fall weather is perfect for you and your children to wander the historic Ribeira district along the Douro River and watch the colorful rabelo boats. Your kids can also ride trams, cross the spectacular, double-deck Dom Luís I Bridge, and take part in interactive exhibits at places like the World of Discoveries museum. Family-friendly cafés offer outdoor seating to sample local treats like Portugal’s signature pastel de nata egg tarts.

Alentejo • Best Place to Avoid the Crowds

For those seeking a quieter, more relaxed Portugal experience away from the tourist throngs in mild fall weather, the Alentejo region is perfect in October. This vast, sparsely populated area of south-central Portugal sees far fewer visitors than the major cities and Algarve beaches at this time of year. Explore charming whitewashed towns like Évora and Monsaraz, sample full-bodied wines at medieval village wineries, and discover the region's rich history and traditional lifestyles while avoiding the crowds, heat of summer, and winter cold.

Madeira • Best Place for Couples or Honeymooners

The Portuguese island of Madeira offers an idyllic escape for couples and honeymooners in October. Known as the "Island of Eternal Spring”, Madeira boasts near-perfect weather at this time of year, with highs around 75°F. Celebrate your vows by admiring breathtaking volcanic landscapes, relaxing on pebbly beaches, or cozying up at romantic quintas serving Madeira's famous fortified wines. You can also hike along levada trails and explore quaint fishing villages to create lasting memories. With its laidback vibe and natural beauty, Madeira in October sets the scene for an unforgettable romantic getaway.

Enjoy the Surf in Peniche

While the summer crowds have dispersed, October ushers in prime surfing conditions along Portugal's central coast near Peniche. Consistent Atlantic swells produce world-class waves at legendary breaks like Supertubos. Join the international surf scene, take a lesson from local instructors, or simply appreciate the talent from shore.

Experience Harvest Festivals and Wine Tastings

Fall is harvest season across Portugal's renowned wine regions and you can join the celebrations in the Douro Valley, sampling the bounty through tastings and vineyard tours.

It is also the time in which locals head for ancient chestnut forests to collect the highly-prized nuts. Follow the smoke from traditional stone furnaces into the wooded hillsides to watch the centuries-old harvesting process, then sample piping hot chestnuts roasted over open fires, along with local wines and regional delicacies like cured smoked meats. Most towns also hold lively harvest festivals with folk music, dancing, and markets selling chestnut-based products like liqueurs and baked goods.

Hike the Lush Peneda-Gerês

With summer's heat subsiding, October is ideal for exploring Portugal's only national park, Peneda-Gerês in the northwest. Trek wooded trails past mountain villages, serene rivers, and granite formations. Spot wildlife like deer, wolves, and golden eagles amid deciduous and pine forests bursting with fall color.

From soaking up the sun on Algarve beaches to sipping new vintages at Douro Valley wineries, Portugal in October dishes up an enticing array of experiences. With comfortable temperatures, fewer crowds, and harvest celebrations, you can immerse yourself in the country's rich history, cuisine, and culture.
