מזג האוויר בHammamet במרץ

March in Tunis is still winter, and regulars say so plainly: the weather is hit and miss, you may get mild sunny days or genuinely atrocious ones, and nights turn chilly with the sun down early. Their average daily maximum of about 19C matches our row's 20.6C, which reads as 18C in a 21.5 kph wind, over a 9.7C night. A jumper or light jacket for the evening and a light raincoat are the items named; our row gives 43.3mm across 6.8 precipitation days. What March offers in exchange is the thing the summer takes away - you can walk the medina and the sites without frying - which is why they pair March with April as the exploring months. The record: humidity 72 percent, 10.1 hours of sun and a 16C sea.

Regulars are specific this month runs meaningfully cooler than what follows, mid-May through June the advice for anyone wanting real heat, days genuinely hot but nights still chilly enough to notice. Our row backs that mild, genuinely dry read, 23.9C over 16.3C nights feeling 16C, with rain light at 27.5mm across 4.8 days and humidity at 71 percent. Regulars are consistent even by the very end of the month hotel pools can still run cold despite warm daytime air, the sea itself lagging well behind the land temperature. Sun protection remains worthwhile given the strong daytime sun even without extreme heat. The sea sits at a cool 19.1C. The record: 12 hours of sun, an 18 kph wind and AQI 53.

October reports here vary widely - some visitors get 20 to 25C with the odd short shower, others catch 30C days, and evenings turn cool enough that a light jacket earns its place. Our row lands mid-range at 25.2C reading as 26C over 19.2C nights, with 46.2mm across 5.2 days. On the sea regulars give a specific, useful piece of timing: the water is cooler at dawn and more swimmable by mid-afternoon once the sun has worked on it, and our column's 24.9C is the kind of figure that hides that daily swing. Cheaper prices and quieter beaches follow once local school holidays end, which the board recommends for a properly unhurried stay. The record: humidity 74 percent, 9.5 hours of sun, a 16.5 kph wind and AQI 46.

September is the month Hammamet regulars pick over August, and the arithmetic backs them: 29.1C against August's 32.2C, reading as 31C rather than 36C, with the sea barely changed at 26.4C. They describe settled weather, water still warm enough for everything, and the crowds thinning once the peak passes while the beach bars and water sports stay open. The honest cost is more rain and a higher chance of a thunderstorm than August - our row doubles the precipitation days to 5.2 across 32.8mm - and the air can still turn muggy. It remains high season, just a quieter grade of it. The record: 22.4C nights, humidity 72 percent, 10.7 hours of sun, a 15.9 kph wind and AQI 47.

Regulars describe August in Hammamet as hot and sweaty but manageable so long as the plan is sunbathing and swimming and the room has air conditioning. Our row's 32.2C reads as 36C at 67 percent humidity, with nights at 23.8C that feel like 27C - the heat does not let go after dark. The comparison they reach for is inland: Tunis runs around 34C by mid-afternoon and Tozeur in the desert nearer 39.5C, so the coast is the cool part of the country rather than the hot one. Rain is a formality at 10.4mm across 2.2 days. July is the peak for prices here, and September keeps the warm sea with less of everything else. The record: 12.4 hours of sun, a 15 kph wind, a 27.6C sea and AQI 48.
