Expect warmth after sunset as well as during the day

Pack mainly light, breathable clothes, but think about how you will sleep as well as what you will wear. With average night lows of 22.7°C, a room with air conditioning is a sensible priority if warm nights bother you. Humidity averages 74%, so the heat may feel less comfortable when you are walking around than the daytime temperature alone suggests. Days reaching 30°C account for 10% of July days: that level of heat is possible, rather than the everyday norm. Plan more active outings for the cooler parts of the day, and leave room for shade and a slower pace around midday.

Good swimming conditions, with plenty of time outdoors

The sea is a strong reason to choose July. At an average of 24.7°C, it is warm enough for swimming rather than just a quick, bracing dip, though personal comfort varies. The July sea temperature ranges from 23°C to 26°C between years, so conditions are not identical every summer. Around 12.9 hours of sunshine within 14.5 hours of daylight give you plenty of scope to spend time outside without doing everything at midday. Keep sunscreen, a hat and drinking water handy, and build shade into your plans. Rain is unlikely to dominate your holiday, but it is still sensible to keep plans flexible rather than assume every day will stay dry.
