Your October weather guide
WarmWeather in Costa del Sol in October
October is a good choice for the Costa del Sol if you want warm days rather than dependable summer heat. Average highs of 22°C make time outdoors comfortable, while nights around 16°C call for a light layer. The catch is rain, with about 7 rainy days across the month, so keep your plans flexible. It suits a break with walks and time by the sea better than a holiday built around swimming.

Nights average 15.7°C; one night in ten drops to 12.8°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest October day here reached 33.6°C (2019-10-01) and the coldest night 3.2°C (2018-10-31).

Some rain (4-8 rainy days): about 7 days with 1 mm or more, 62 mm in total. Year to year it varies a lot - the wettest October was 2018 with 295 mm, the driest 1998 with 0 mm. Humidity averages 76%.

Is October a good time to visit Costa del Sol?
It is a reasonable choice: warm days. The best months for Costa del Sol on our scoring are July, August, June; months averaging 25°C or more: Jun, Jul, Aug, Sep.
Warm afternoons, cooler evenings
Pack for mild warmth rather than constant heat. Light clothes should suit typical afternoons, but bring a jumper or light jacket for evenings: the coldest nights can fall to 13°C or below. Warmer spells are possible, with 12% of days reaching 25°C, though you should not plan around that level of warmth. If strong heat puts you off travelling in summer, October is a reasonable compromise. You can spend time outside without expecting every afternoon to feel hot, while keeping an extra layer handy when temperatures drop. Sun protection still belongs in your bag, especially for long stretches outdoors.
Useful sunshine, but keep swimming expectations modest
There is enough sunshine to make outdoor plans worthwhile, averaging about 6.1 hours within 11 hours of daylight. That is not a promise of clear skies all day, and the rain means a waterproof layer and flexible plans are sensible. Leave room to move outdoor activities around rather than relying on an uninterrupted run of dry weather. The sea is another compromise: at an average 19.3°C, it feels bracing rather than comfortably warm. A short dip may appeal if you tolerate cool water, but this is less convincing for a swimming-led holiday. Time beside the sea is a safer focus than expecting long, relaxed swims.
