Your August weather guide
HotWeather in Hammamet in August
August suits a Hammamet holiday if you want hot days and warm-water swimming, but it is less comfortable for being active through the afternoon. Average daytime highs are around 31°C, nights stay near 23°C and the sea reaches about 27°C. For a UK traveller, the main adjustment is sustained heat rather than unreliable weather. Go then if swimming and time in the shade appeal; reconsider if you prefer cool evenings or long walks without planning around the sun.

Plan your day around the heat
August is Hammamet's warmest month, and the heat is consistent: 76% of days reach 30°C. The hotter days reach around 34°C or more, so the average should not be treated as a ceiling. Put walks and anything energetic earlier in the day, leaving the middle of the day for shade, rest or somewhere cooled. Pack loose, lightweight clothing, a hat and sun protection, and keep drinking water handy. Nights averaging 23°C offer only limited relief, so air conditioning is a sensible priority when choosing accommodation. This is a better fit for travellers who enjoy heat than those who need a cool night to sleep comfortably.
Warm seas and plenty of time outside
The sea is a strong reason to choose August: at around 27°C, it is comfortably in swimming territory rather than a bracing dip. That makes a swim-led holiday a natural fit, although warm water should not be mistaken for protection from the sun. Sunshine averages about 11.4 hours within 13.4 hours of daylight, giving you room to shift outdoor plans away from midday without losing the whole day. Use shade between swims and keep a light cover-up close by. With humidity at 69%, the warmth can feel sticky, so breathable clothes are more useful than heavy layers. Expect warm evenings rather than a distinctly cool end to the day.
