Expect reliable heat, not just occasional hot days
Warm weather is a dependable part of July: 99% of days reach 25°C, while 36% reach 30°C. That makes it a strong choice if warmth is your priority, but less suitable if you prefer to walk around all afternoon without thinking about the heat. Loose, breathable clothing, shade breaks and easy access to drinking water should shape your plans. With humidity averaging 65%, do not assume the dry weather will always feel crisp. Evenings offer some relief, but average lows around 22°C mean they remain warm rather than cool. Accommodation with air conditioning is a sensible priority if heat affects your sleep.
Good swimming weather with plenty of daylight
The sea is a clear reason to choose July, averaging 25.3°C, with a year-to-year range of 24°C to 26°C. That puts it comfortably in swimming territory rather than making a dip something to brace yourself for. There is also plenty of time outdoors, with about 11.9 hours of sunshine within 14.4 hours of daylight. Use that long day to spread activities out instead of packing everything into the hottest hours. Sunscreen, sunglasses and a hat deserve space in your bag, even if you mainly plan to swim. The appeal is warm water and reliable outdoor weather; the trade-off is managing prolonged sun and heat.
