Europeans on summer vacation flock to Tunisia's beaches to bask in the Mediterranean sun (average daily highs range from 90-100+ degrees). Prices rise appreciably, but the coastal resorts are especially animated and festivals are common.
Off Season: November to March
The weather is often rainy and chilly, but if your focus is culture and history this is an ideal time to visit, as you’ll have the sights to yourself. Daytime temperatures average in the 60s, though the thermometer drops into the 30s at night.
Sweet Spot: April to June, September to October
The sun shines most of the time, the sea is generally warm enough for a dip, and prices are below their summer highs. Thanks to winter rains, the countryside is at its greenest in the spring. Expect weather in the 70-80 degree range.
