What's the weather like on Costa del Sol in September?Sitting in southern Spain on the country’s Mediterranean coast, you'll get high temperatures and hardly any rain if you're going to the Costa del Sol in September. It’s a bit cooler than the peak of summer and September’s the last month with not much rain before autumnal showers arrive in October. The Costa del Sol’s close to North Africa and the Sahara Desert which means hot winds can affect it when they blow in from the desert and drive temperatures up.
AveragesThe typical high in Marbella is 26ºC in September so it’s ideal for lounging by the pool or on the beach. Things are nice and pleasant in the evenings too which cool to 16ºC. The sea temperature is 23ºC, while humidity’s low. There’s 15mm of rain over three days, and you can expect 12 hours of daylight with eight hours of sunshine each day. UV levels will be high so pack some sun cream, and sunset’s around 8.45pm at the start of the month and gradually gets earlier.
