מזג האוויר בסוסה 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.

Sousse's own forum doesn't sugarcoat January: it's genuinely changeable winter weather, with a warm window roughly late morning to early afternoon when the sun is out, followed by a sharp drop as soon as it sets - dusk arrives by 5:30pm and temperatures fall quickly after. Posters recommended packing both a light fleece and a proper raincoat for the odd shower, though January is actually one of Sousse's drier months overall - a run of clear, dry days is more typical than a rainy stretch. It's not a beach-weather month, but midday sun on a clear day is still genuinely warm and worth planning around.

Forum posters don't undersell it: July averages around 30C but regularly climbs past 35C, described in escalating terms as hot, really hot, and 'possibly stifling' on the worst days - even locals admit the July-August stretch is a lot to handle. The beaches themselves get consistent praise - sandy, not rocky, with warm, swimmable Mediterranean water - and strong suncream is treated as essential given how intense the sun gets. For an escape from the midday heat, posters point to the Sousse medina's museum as a genuinely cool indoor break between beach sessions.
