Djerba is Tunisia’s southernmost beach island, in the far south-east, joined to the mainland by a causeway, and it is the driest and sunniest of the main resort areas. Winters are the mildest on the coast and rain is rare, which makes it the standard choice for off-season sun. This guide gives approximate month-by-month figures for Djerba so you can see how it compares with Sousse, Hammamet and Tunis.

Why Djerba is the sunniest resort
Djerba gets roughly 7 hours of sunshine a day even in January and December, against about 5 hours in Tunis and Hammamet. Rainfall is also far lower: about 22 mm in January and only about 4 rain days, compared with 66 mm and 11 days in Tunis. Winter highs are around 16-18°C with lows of 9-10°C, so a coat is rarely needed in daytime, although evenings can feel cool. July and August reach approximately 32°C by day and 22-23°C at night, and the island is flat and exposed, so shade matters.
Sea temperature around the island
Djerba’s sea is among the warmest in Tunisia in late summer. It is approximately 14-15°C in February and March, 17°C in April, 20°C in May and 23°C in June, then 26°C in July and 28°C in August. September stays around 27°C and October is still about 25°C, so the swimming season runs from late May or June right through to October for most people. Shallow beaches near Midoun and Sidi Mahrez warm faster than open water. See our Djerba beaches guide for where to swim.
Rain, wind and the autumn storm season
Djerba is dry for most of the year. The main exception is October, when around 48 mm of rain falls over about 4 days, often in short heavy bursts that can flood roads briefly. Spring is almost dry, with only about 7 mm in May and almost nothing from June to August. Wind is the main nuisance: the island is open to sea breezes year-round, which cools the summer heat but can make a winter beach day feel chilly and cause rough water for ferries and boat trips.
Best Time to Visit Djerba by Trip Type
