Expect persistent heat, not just the occasional hot day
Days reach 30°C on 90% of occasions in July, so you should be comfortable with sustained heat before booking. The hottest 10% reach 36°C or more, making shade and breaks indoors sensible parts of the day. Put anything energetic in the morning and leave the hottest hours for a slower pace. Loose, lightweight clothing, sun protection and drinking water are priorities. Evenings offer some relief, but an average night low of 23°C means they are still warm rather than fresh. If warm bedrooms affect your sleep, prioritise air conditioning when choosing accommodation. July suits heat lovers more than travellers who want comfortable conditions for long walks.
Warm swimming water and little need for a rain plan
The sea averages 26°C, making July a straightforward choice if swimming is central to your holiday. Its usual year-to-year range of 25°C to 27°C keeps it firmly in comfortable swimming territory. Rain is unlikely to shape your plans, with about 1 rainy day during the month, though that is not a guarantee of an entirely dry stay. Around 13.8 hours of sunshine a day gives you plenty of scope to enjoy the water outside the hottest part of the day. The catch is exposure: sunshine this persistent calls for shade breaks and regular sun protection, even when you spend much of your time swimming.
