Thời tiết Sousse vào tháng 9

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.

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.
