What’s the weather like in the Algarve in September?
Sitting in the south of Portugal close to the coast of North Africa, the Algarve enjoys long, hot summers that reach out into September. The month’s technically the start of autumn, but you’ll get lots of great weather with plenty of sun and hardly any rain.
One of the sunniest places in Europe, the Algarve also has the best weather in Portugal. It’s protected from northern and Atlantic winds by the mountains which divide the north and south of the country, so you’ll be warmer and drier in the Algarve. Atlantic winds are stronger offshore than on the coast, which makes for great sailing and water sports. With the Mediterranean to the east and the Atlantic to the west, the Algarve’s a bit warmer and drier in the east.
In Faro, the Algarve’s capital, you’ll get a lovely average high of 27ºC in September, which cools to a pleasant 17ºC at night. The sea temperature’s 23ºC, while humidity’s low and there’s just 10mm of rain over four days. You can expect 12 hours of daylight with nine hours of sunshine each day, and make sure you take lots of sun cream as UV levels will be high. At the start of September the sun goes down nice and late at 8pm, which gets earlier as the month goes on.
