The northern part of Tunisia, where most of the holiday resorts are based, has a typical Mediterranean climate. The summers are dry and hot – sometimes quite a bit hotter than you may have been used to if you have visited Spain or Greece, for example. In winter the north remains mild, and a little rain does fall. The further south you go, towards the Sahara, the hotter and drier it becomes.
Tunis and north-eastern Tunisia have a Mediterranean climate, with hot, dry summers and mild, rainy winters. Average temperatures over the summer months are around 25 degrees C in Tunis, though they can top 30 degrees on the hottest days. Sea breezes help cool the resorts along the coast while inland towns are often hot and dusty. In December and January, the wettest months, temperatures average 6 to 11 degrees C. Spring is a comfortable 16 degree C average, though in spring and autumn Tunis has, on average, seven days of rain out of every month. The best times to visit are usually late spring (May-June) and autumn (September-October) when temperatures are most pleasant.
