Your April weather guide
WarmWeather in Sousse in April
April is a good time for Sousse if you want warm afternoons rather than reliable swimming weather. Average daytime highs are around 23°C, but nights fall to around 12°C and the sea is cold at 16°C. For a UK traveller, that makes it a sensible choice for spending time outdoors without intense heat being the norm. The catch is that you'll need evening layers, and beach weather does not necessarily mean comfortable sea bathing.

Warm afternoons, cool evenings
Pack for a change between daytime warmth and evening chill, rather than treating April as summer. Light clothes should suit typical afternoons, while a jumper or jacket will be useful after sunset. The coldest nights can fall to around 9°C or below, so long trousers are a sensible addition. There is scope for hotter weather: 27% of days reach 25°C, but only 4% reach 30°C. That balance suits travellers who enjoy warmth without wanting strong heat throughout their stay. On warmer afternoons, leave room for a shaded break at midday; on cooler days, keep a layer handy rather than relying on sunshine alone.
Useful sunshine, but a cold sea
With about 7.7 hours of sunshine a day, April offers time for sitting outside and enjoying the warmth. The main limitation is the water: the sea averages 16.1°C, with a year-to-year range of 16°C to 17°C. That is cold rather than merely refreshing, so do not make long, comfortable swims the centre of your plans. A warm afternoon on land will not remove that chill. April therefore works better for travellers who are happy spending time by the sea than those who want to spend much of the day in it. Bring sun protection, but keep your plans flexible enough to cope with rain.
