Where to stay: Hammamet for less intense heat
Hammamet is the best fit if you want August warmth without choosing the hottest option: its daytime average is 31°C, compared with 35°C in Sousse. Port El Kantaoui sits between them at 34°C, so it is closer to Sousse for daytime heat. The difference matters most if you expect to spend much of the day outdoors rather than in the water or shade. Evenings offer little reason to choose between them, with nights averaging 22°C in Sousse and 23°C elsewhere. Sea temperatures are the same at 27°C, so choosing milder Hammamet does not mean giving up warm water.
What to expect from an August day
With 11.4 hours of sunshine and an average of 2 rainy days, August favours plans built around being outdoors, but the heat needs more attention than the rain. Keep walking and other exertion for the morning or later in the day, and leave the middle of the day for shade or an indoor break. Pack light, loose clothing, a sunhat and sun protection, and keep drinking water handy. Nights averaging 23°C mean you should not expect a reliably cool end to the day; accommodation with cooling is a sensible priority if warm bedrooms make it hard for you to sleep.
