What’s the weather like in Portugal in September?

Located on Europe’s Iberian Peninsula, Portugal enjoys warm weather in September. It’s the most westerly country in Europe, and although there are differences in climate across the country, the most popular holiday spots have hot weather and not much rain at this time.

Climatic variances

There’s different weather between the north and south of Portugal, with the south having fairly typical Mediterranean weather. September’s nice and hot in the Algarve, while Atlantic winds mean the west coast’s windier. The Gulf Stream warms things up as you go up the coast, while temperatures can be higher inland. Popular Madeira’s an island that’s far closer to Africa than Portugal, so has even hotter weather than the mainland.


Averages are different around Portugal, but capital Lisbon on the west coast gives a good indication of the weather. It has an average high temperature of 27ºC during September, with things staying pleasant in the evenings. At 20ºC the sea’s at its highest average temperature, while humidity’s low and ranges between 40% and 90%. Rainfall’s around 33mm for the month over six rainy days.


During September you can expect 12 hours of daylight with nine hours of sunshine each day, while UV levels will be high. The west coast has lots of places to enjoy a sunset, which is at 8pm at the start of the month.

Things to Do

You’ve probably got your eye on the coast if you’re going to Portugal in September, and there’s some great beaches to kick back on and soak up the sun. The Algarve has some of the country’s best beaches, as well as lively spots such as Albufeira, which has late night clubs. There’s some great golf courses in Portugal although it might be a bit hot in September for a full 18 holes. Surfing’s popular all year round, although if you’re after the biggest waves then they arrive over winter.
