Portugal Weather in August
What’s the weather like in Portugal in August?
Portugal’s in Western Europe on the Iberian Peninsula, surrounded by Spain and the North Atlantic Ocean. August is the height of summer, and you’ll get lots of sun and not much rain if you’re going at this time. There’s some differences in weather around the country though. The south, where you’ll find the popular Algarve region, has a fairly typical Mediterranean climate, while regions along the west coast are warmed by the Gulf Stream. You’ll have cool breezes all along the coast which take the edge off August’s high temperatures, and the island of Madeira has even hotter weather than the mainland.
The average high in capital Lisbon is 28ºC in August and things stay nice and pleasant in the evenings, which cool to 18ºC. The sea temperature’s 20ºC while humidity’s moderate. There’s just 5mm of rain over two days and 14 hours of daylight with 11 hours of sunshine each day. UV levels will be moderate, while sunset’s nice and late at around 8.45pm at the start of the month.
