Expect proper summer heat

July suits travellers who enjoy heat, but it may feel tiring if you prefer being outdoors and active throughout the day. Temperatures reach 30°C on 37% of days, while the hottest days can reach 32°C or more. Plan longer walks for the morning and leave room for shade or an indoor break around midday. Loose, light clothing, a hat and sunscreen belong in your daily bag, and accommodation with air conditioning is a sensible choice if heat affects your sleep. The average night low is 20°C, so evenings offer some relief without reliably feeling cool.

Warm water and plenty of daylight

The sea is a strong reason to choose July. At an average of 24°C, it is warm enough for swimming rather than just a quick dip, although your own tolerance still matters. The July sea temperature ranges from 23°C to 25°C between years, so the swimming outlook is fairly consistent. There are about 11.6 hours of sunshine within 14.9 hours of daylight, leaving plenty of flexibility to move outdoor plans away from the hottest part of the day. Take sun protection seriously even when swimming makes you feel cooler, and build shaded breaks into time spent beside the water.

Allow for rain without planning around it

July is not guaranteed to stay dry, with about 5 rainy days during the month. That is enough to make a light waterproof useful, but rain need not be the main factor in deciding when to go. Keep outdoor plans flexible and have something indoors in mind for wet weather rather than assuming every day will suit swimming. Rainfall varies considerably between years, so the monthly average cannot promise a dry holiday. For packing, prioritise clothing for heat and sun, with a light layer for cooler evenings. A forecast nearer departure will help you decide how much wet-weather clothing to bring.
