Weather in Portugal in the summer
In the summer, you can count on plenty of sunshine and heat all across Portugal. The Algarve and the coast up to Lisbon see very little rain, with temperatures generally around 86°F (30°C), sometimes hitting 95°F (35°C) or higher in inland areas. The Algarve enjoys about 12 hours of sunshine each day at the peak of summer, and with sea temperatures around 71.6°F (22°C), it's perfect for swimming and water sports.
Central Portugal can get extremely hot and dry, with places like Évora and Beja often soaring above 104°F (40°C). Up in the north, around Porto and the Costa Verde, temperatures are usually cooler, ranging from 77°F (25°C) to 86°F (30°C), and there’s a higher chance of summer showers, which can be a nice break from the heat.
Coastal areas benefit from refreshing sea breezes that make the heat more manageable, but inland cities like Lisbon can feel especially warm due to the urban heat island effect.
