What’s the weather like in Tunisia in September?

Located in the middle of North Africa’s Mediterranean coastline and with the Sahara Desert dominating the south, Tunisia’s very much still in the full swing of summer in September. There’s some different weather around the country, but at popular holiday spots along the Mediterranean coast you’ll get lots of hot and sunny weather, although it’s a bit cooler than the peak of summer.

Regional variances

Tunisia has changes in the weather because of its geography, although it’s generally known for its hot weather. The Sahara makes things hot and dry in the south with big differences between day and night. You’ll find things less extreme on the Mediterranean coast in the north and east, thanks to cool sea breezes, while the Cap Bon peninsula has quite comfortable conditions that make it popular as a holiday destination.


The average high in popular Hammamet during September’s 30ºC, and this only drops to 20ºC at night so you won’t need to bring many warm clothes. The sea temperature’s a warm 26ºC so it’s perfect for swimming, while humidity’s moderate. There’s 36mm of rain over four days, and you can expect 12 hours of daylight with nine hours of sunshine at a high UV level. Take care of your skin with plenty of sun cream in the sun, which sets at 6.45pm at the start of the month.
