Wetter in Sousse im Mai

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.

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.
