Your August weather guide
HotWeather in Andalucia in August
August is a good time for Andalucia if you want hot, dry weather and warm-water swimming, but less suitable if you prefer keeping active through the middle of the day. Average highs are around 30°C, nights stay near 21°C and the sea averages 23°C.

Expect heat that shapes your day
Daytime temperatures reach 30°C on 40% of days, while the hottest days reach 33°C or more. That makes August better suited to a relaxed pace than a schedule packed with outdoor activity. Choose accommodation with air conditioning if warm bedrooms make sleeping difficult, and keep the middle of the day flexible for shade or an indoor break. Loose, light clothing is the practical choice, with sun protection close to hand. Average night lows of 21.4°C mean evenings offer some relief rather than a reliably cool finish. These are regional averages, so do not expect identical conditions everywhere in Andalucia.
Good swimming weather, with little need to plan around rain
The sea averages 23°C, with a year-to-year range of 22°C to 24°C, making August a good choice if swimming is central to your holiday. Sunshine averages about 11.2 hours a day, leaving plenty of scope to enjoy the coast without spending the hottest part of the day in direct sun. Rain is usually a minor interruption rather than something to build your plans around, with about 1 rainy day during the month. Pack mainly for heat and sunshine, but check the forecast before travelling rather than assuming every day will be dry. The main planning challenge is managing sun exposure, not finding a dry window.
