Hot days without much overnight relief
The heat is reliable: 99% of days reach 25°C, although temperatures reach 30°C on only 15% of days. That makes August consistently warm rather than routinely scorching, but hotter spells can still make being outside tiring. Humidity of 75% can add to the muggy feel, particularly when nights offer little relief. Plan anything energetic for earlier in the day and leave room for shade and breaks around midday. Light, loose clothing is a sensible starting point, and air conditioning is worth prioritising if you struggle to sleep in the heat. This is less well suited to travellers who prefer a crisp evening after a warm afternoon.
Warm swimming water and little rain
The sea is a strong reason to choose August. At an average of 26.2°C, it is warm enough for comfortable swimming rather than a bracing dip; the year-to-year range of 25°C to 27°C also points to reliably warm water. Rain is unlikely to dictate your plans, with about 1 rainy day during the month, though a completely dry stay is not guaranteed. Around 12.6 hours of sunshine gives plenty of scope for time outdoors, but also makes shade, sunscreen and drinking water daily priorities. You do not need to spend the hottest part of the day in direct sun to make good use of the weather.
