June to September is the best time for festivals and beach-going

Porto’s summer brings long warm days and plenty of cloud-free skies. The city gets less rainfall at this time of year, though even in summer, occasional showers are possible. June is also the kickoff to Porto’s busiest time of year for events, with outdoor music festivals, saintly processions (including one by fishing boat) and some of the city’s biggest celebrations.

The temperatures averages around 23°C (73°F) but periodic heatwaves push temperatures into the high 30°Cs (high 90°Fs). July and August are the warmest months of the year, and you’ll find tripeiros (Porto locals) cooling off at Praia de Matosinhos and other nearby beaches. Keep in mind that even on the hottest days, ocean temperatures can feel brisk on Portugal’s northern beaches.

Predictably, summer coincides with the peak visitor season in Porto. You can expect higher hotel prices and bigger crowds wherever you go, and you’ll want to reserve well ahead at top restaurants.

Enjoy Porto's wine and mild weather in March to May and October

Porto has two shoulder seasons and they fall during the spring and autumn months. Colorful blooms fill the parks around the city from late March to early May, and if you take a day trip to the countryside, you can see wildflowers on scenic hikes through northern Portugal’s nature reserves.

Late September and October bring bright fall colors to the city’s parks and tree-lined streets. The spectacle is especially dramatic along the banks of the Douro River upstream from Porto. This is also grape-harvest season at wineries in the Douro Valley, so you'll have the opportunity to see wine-making and grape-stomping in action.

The weather is a bit of a mix at this time of year, with more rain than in summer but fewer wet days than you’ll see in winter. Temperatures are near perfect for outdoor activities, with daily highs of around 17°C (63°F) in March, and around 20°C (68°F) in October.

November to February is the cheapest time to visit Porto 

Porto has a reputation for cold, rainy days during the winter months. December is the city’s wettest month, with an average of around 15 days of precipitation. Even on those rainy days, however, you can get patches of dry weather in between the storms.

Traveling at this time of year means dressing in layers. You might have a cold, misty morning, followed by midday sunshine with highs of around 15°C (59°F) and evening showers. January is the coldest month of the year, though the evening lows rarely fall below 5°C (41°F).

In exchange for a bit of chilly, damp weather, you can avail of rock-bottom prices for flights and accommodations. Count on lodging discounts of up to 50% off high-season rates.
