Reliable warmth, but plan around the midday heat

Warm weather is the norm rather than a bonus: 97% of August days reach 25°C, while 22% reach 30°C. That makes light, breathable clothing a sensible starting point, with a hat and sun protection for time outdoors. Humidity averages 67%, so the warmth may feel less comfortable if you are walking around in the middle of the day. Put more active plans earlier or later, and leave room for shade and breaks at midday. With average night lows of 22°C, evenings are warm too. If you struggle to sleep in heat, prioritise accommodation with cooling rather than assuming an open window will be enough.

Dry days and comfortable swimming conditions

August offers about 11.2 hours of sunshine within 13 hours of daylight, giving you plenty of scope to spend time outside without making midday your main outing. Rain is unlikely to disrupt plans, so waterproofs need not dominate your packing, although dry averages are not a guarantee for every stay. The sea averages 22.8°C, with a year-to-year range of 22°C to 23°C: warm enough for swimming, though personal comfort varies. This combination suits travellers who want regular swims and time by the water. The catch is sustained sun exposure, so keep shade, sunscreen and drinking water part of the routine even when a swim makes you feel cooler.
