Tunisia is experiencing this Friday, June 12, a day marked by strong thermal contrasts between the northwest, still cool at dawn, and the Saharan south already scorching.

Tozeur will rise to 36°C by midday, while Jendouba will hover around 15°C in the early morning before warming up. The sky remains largely clear across the territory, accompanied by UV indices close to 10, indicating a particularly aggressive sun.

Greater Tunis

The capital and its metropolitan area experience the morning in pleasant mildness, with minimums between 19 and 20°C. The thermometer will gradually rise to 29 or 30°C in the afternoon. The sky remains mostly cloudless to clear, and the northwest wind blows gently, not exceeding 6 km/h. Humidity stays around 62%, making the atmosphere slightly heavy in the evening. A typical early-summer day for Tunisians.

Sahel and Cape Bon

The eastern coastal governorates enjoy a mild morning around 20 to 21°C, followed by a moderate afternoon between 25 and 27°C. Cape Bon and the Sahel benefit from a steady northwest wind at 8-11 km/h, bringing a pleasant sea breeze. Humidity ranges from 57 to 67%, creating relatively heavy air over Nabeul and Mahdia. The sky remains clear to partly cloudy, ideal for seaside activities, but beware of UV reaching near 10 along the coastline.

Northwest

The heights of the northwest register the coolest mornings in the country: Jendouba and Le Kef show 15°C at sunrise, while Béja and Siliana hover around 16°C. In the afternoon, the mercury rises to 27-29°C under a clear sky. Humidity is pronounced in this zone, exceeding 75% in Jendouba and Le Kef, with air saturated early in the day. Winds remain very light, between 2 and 5 km/h. Bizerte, by the sea, benefits from a stronger breeze at 10 km/h and remains the coolest in the afternoon at 24°C.

Center

Kairouan, Kasserine and Sidi Bouzid experience a significant warming: maximums rise to 28-32°C under relentless sun. Morning minimums remain mild, between 19 and 21°C. Winds stay light, between 3 and 4 km/h, and humidity sits between 48 and 58%, making the heat more bearable than in midsummer. UV indices reach 10.4 in Kasserine and Sidi Bouzid, necessitating particular vigilance outdoors.

South

The vast southern Tunisia steps straight into the peak of the summer furnace. Tozeur and Kebili peak at 36°C, with minimums already high at 23-24°C. Gafsa and Kairouan (listed as center) reach 32°C. The southeast coast remains milder: Gabès tops at 27°C, Médenine and Tataouine at 29°C, thanks to maritime influence. Humidity climbs to 83% in Tataouine, creating a suffocating sensation despite moderate temperatures. Winds remain generally light, between 4 and 7 km/h, with the exception of Tozeur and Kebili where they reach 7 km/h from the east.

Three notable weather facts

• Tozeur and Kebili brush 36°C, marking the country’s heat peak this Friday.
• A morning thermal gap of 21°C separates Jendouba (15°C) from Tozeur (36°C), illustrating the territory’s climatic diversity.
• UV indices exceed 10 in the center and southwest, requiring enhanced solar protection.

Practical advice

With very high UV indices, wearing sunscreen, sunglasses and a hat is essential when you are outdoors. In the Saharan south, stay hydrated regularly and avoid prolonged exposure between 12:00 and 16:00. The northwest experiences marked temperature swings: plan a jacket for the morning and light clothing for the afternoon. On the coast, the sea breeze provides welcome comfort, but beware of sunburn along the shore.
