Reliable warmth, rather than constant extreme heat

Expect to dress for heat most days: 87% reach 25°C, but only 6% reach 30°C. That makes July a strong option if you want dependable warmth without choosing somewhere routinely much hotter. Humidity averages 73%, so the air can feel muggy, particularly when you are walking rather than sitting in the shade. Keep more energetic plans for the morning or later afternoon, and leave room for a slower spell around midday. Light, breathable clothes are the sensible default. With average night lows of 21.6°C, air conditioning is worth prioritising if you struggle to sleep in warm rooms.

Plenty of sun, with a small chance of rain

July gives you about 12 hours of sunshine within 14.6 hours of daylight, leaving plenty of scope to spend time outdoors without packing everything into midday. The practical trade-off is prolonged sun exposure: bring sunscreen, sunglasses and a hat, and make shade part of your plans rather than an afterthought. There are about 3 rainy days, so a completely dry stay is not guaranteed, but rain is unlikely to be the main reason to reject July. Keep plans flexible if a wet spell arrives. For most travellers, sun protection deserves more attention in the packing than substantial wet-weather clothing.

A comfortable month for swimming

The sea averages 25.4°C, making swimming a clear reason to choose July rather than merely something to attempt on a hot afternoon. The year-to-year range is 24°C to 26°C, so the water is generally warm enough for travellers who dislike a bracing dip. That pairs well with the hot daytime weather, though time by the water still calls for shade and sun protection. July suits a holiday built around swimming and unhurried outdoor time more than one involving sustained exertion in the middle of the day. If your priority is cooler walking weather or distinctly fresh evenings, the warmth is the main compromise.
