The shape of the year: mild winters, hot summers

Winter suits travellers who prefer walking to lying on a beach, but mild does not mean warm throughout the day. January nights average 8°C, so bring a jacket for evenings and layers for daytime changes. February stays similar, before March lifts daytime temperatures to 19°C and April to 22°C. That makes spring a sensible choice for city stays, although rain remains a possibility. May feels warmer at 26°C, without the peak summer heat. For an autumn city break, November offers daytime temperatures of 21°C and nights of 13°C. A light waterproof is useful in these cooler seasons, with rain on around 6 days a month.

When to go for the beach

June is a good compromise if you want hot beach weather without the highest daytime temperatures: days average 30°C, the sea reaches 22°C and rain falls on around 2 days. July and August bring the strongest heat, so plan shade and a slower pace at midday. August has the warmest sea at 27°C, but nights remain warm at 23°C. September keeps the sea at 26°C as daytime heat eases, making it appealing for swimming. October trades some reliability for milder conditions: the sea is still 24°C, but 7 rain days make flexible plans sensible. May suits beach lounging better than travellers who want a warm swim, with the sea at 19°C.

Sousse, Hammamet and Port El Kantaoui

Sousse is the warmer choice overall, with an average daytime temperature across the year of 25.2°C, compared with 22.5°C in Hammamet. If warmth is your priority outside summer, that gives Sousse an edge; if you prefer a cooler base, Hammamet is worth considering. These annual averages are not a promise of the same gap in every month. For a stay in Port El Kantaoui, use the seasonal pattern as a planning guide rather than assuming it is warmer or cooler than its neighbours. Keep the scope in mind too: this guidance suits holidays around these destinations, not firm expectations for every part of Tunisia.
