The best time to visit Kasserine is during the spring (March to May) and autumn (September to November) when the weather is mild and pleasant.
During spring, temperatures are agreeable, typically ranging from 60°F to 75°F (15°C to 24°C). This season is ideal for exploring the Roman ruins of Sbeitla, located just a short drive from Kasserine, as the natural surroundings are green and flowering. It's also a comfortable time for outdoor activities like hiking in the nearby Djebel Chambi National Park, Tunisia's highest mountain, without the intensity of summer heat.
Autumn also offers comfortable temperatures, generally between 65°F and 80°F (18°C to 27°C), making it suitable for sightseeing and exploration. The cooler air is conducive to visiting historical sites and enjoying the local markets.
