Tunis weather in September

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 are direct this counts as genuinely not pool or beach weather, cold wind a real factor at times, though a sheltered spot on an occasional sunny day can feel surprisingly pleasant. Our row backs that mild, still-cool read, 18.6C over 7.8C nights feeling 5C, with 35.4mm of rain across 7 days and humidity at 73 percent. Regulars are consistent this suits walking around and eating outdoors during the day, a light jacket or cardigan handy for chilly evenings rather than a full winter coat. The sea sits at a cold 14C, firmly out of season for swimming. The record: 8.9 hours of sun, a 20 kph wind and AQI 65.

Regulars describe this month as still genuinely warm, high 20s to low 30s by day, with any rain showers typically brief and quick to clear into bright sunshine rather than settling in. Our row backs the lingering heat, 27.8C over 16.8C nights, with 51mm of rain across 5.7 days - one regular reports never seeing more than a couple of rainy days across three separate October visits, consistent with rain here being a real but occasional feature rather than a defining one. Evenings do turn genuinely chilly enough that a light jacket is standard advice even on an otherwise hot day. The sea stays warm at 24.7C. The record: humidity 72 percent, 9.4 hours of sun, a 17.8 kph wind and AQI 46.

Tunisia-forum threads on August weather (Tunis specifically among the destinations discussed) call it hot, sunny and reliably dry, afternoon readings regularly around the mid-30s Celsius. One experienced visitor offers a specific mental trick: subtract about 6 degrees from the forecast number to get a sense of how the heat will actually feel, since the dry heat here reads differently than a humid climate at the same temperature. Posters flag air conditioning as inconsistent across accommodation, worth confirming before booking. Regulars steer visitors with flexible dates toward April, May, or mid-September instead, more comfortable without August's peak intensity. Light, breathable clothing and real sun protection are the standing packing essentials regardless of when a trip lands. The record: 36.1C days feeling like a punishing 38C, 23C nights, just 12mm across 2.8 days, a 28.7C sea, 63 percent humidity and 12.3 hours of sun.

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.
