Expect heat that shapes your day

Sousse is much hotter than London in July: its average daytime high is 34.6°C, compared with 21.8°C at home. That makes early outings and relaxed afternoons a more comfortable approach than long walks at midday. The hottest days need extra care, with the warmest 10% reaching 39.1°C or more. Pack loose, lightweight clothes, a hat and sun protection, and make access to shade and drinking water part of your plans. Air conditioning is a sensible accommodation priority if you struggle to sleep in warmth. Evenings offer some relief, but an average night low of 21.7°C means you should not expect a distinctly cool end to the day.

Warm swimming water, with little rain to plan around

The sea is a strong reason to choose July, averaging 25.4°C, with a year-to-year range of 24°C to 26°C. That suits travellers who dislike a chilly swim, although warm water may feel less cooling when the air is very hot. Sunshine averages about 12.9 hours within 14.2 hours of daylight, so there is plenty of scope to swim outside the fiercest midday heat. Rain is unlikely to disrupt plans, with about 0 rainy days, but that is not a guarantee of completely rain-free weather. Light clothing and sun protection deserve more space in your bag than wet-weather kit, and shade breaks should be part of a beach day.
