Mild afternoons, cool evenings

January is Hammamet's coldest month, so treat it as winter with milder afternoons rather than an early taste of summer. A light jumper or layered outfit is a sensible starting point for daytime, with a warmer jacket for evenings. The warmer days reach around 18°C or more, which can make time outdoors comfortable, but colder nights can drop to around 7°C or below. Plan your longer outings around the middle of the day, when warmth is more likely to help. This suits travellers who prefer walking in mild conditions; it is a poor match if your holiday depends on reliable heat.

Enough sunshine to enjoy, with rain to work around

There are about 5.1 hours of sunshine a day within 9.8 hours of daylight, so January offers scope for outdoor plans without promising clear skies throughout. About 7 rainy days means waterproof clothing earns its place in your luggage. Keep your schedule flexible rather than making every day depend on dry weather, and use sunny spells for time outside. A raincoat and shoes you are comfortable wearing in wet conditions are more useful than packing only for the beach. The balance suits a traveller happy to adjust plans, but less so anyone seeking an uninterrupted week of sunshine.

The sea is the main limitation

At an average 15.7°C, the sea is cold rather than comfortably swimmable. Its January range of 15°C to 16°C also leaves little reason to expect a much warmer swim in a different year. If getting into the sea is central to your holiday, January is difficult to recommend. You can still make time by the coast part of the trip, but pack for sitting or walking outdoors rather than assuming swimwear will get much use. Choose this month for a mild change of scene and manageable daytime temperatures, not for the usual warm-water resort holiday.
