Where to go for the warmest weather

Sousse and Port El Kantaoui offer the strongest case for daytime warmth, both averaging 20°C. There is little weather reason to favour either: their night temperatures, rainy-day averages and sea temperatures also match. Hammamet averages 18°C by day, so it is a less obvious choice if warmth is your priority, although its nights are slightly milder at 11°C. Expect comfortable conditions for walking when the sun is out, rather than dependable heat for lounging in swimwear. Hotter spells are possible: in Sousse, 11% of March days exceed 25°C. Treat that warmth as a bonus, not the basis of your packing.

What to pack and how to plan your days

With 6.8 hours of sunshine a day on average, March gives you scope for outdoor plans, but leave room to adjust them. Tunisia averages 6 rainy days during the month; Sousse and Port El Kantaoui match that, while Hammamet has 7. A light waterproof is a sensible addition to your bag, alongside lighter clothes for sunny afternoons and a jumper or jacket for evenings. Make use of the warmer part of the day for relaxed time outside, and keep an indoor alternative for wet weather. This is a better fit for travellers happy to dress in layers than for anyone wanting consistently hot beach weather.
