Weather overview
Ам-Тиман sits in the heart of Chad, where the climate splits the year into two distinct halves: a long dry season and a shorter, intense rainy period. From November to April, the skies over Ам-Тимане stay almost cloudless, with barely any rain and plenty of sun. The air grows hotter as the months pass, peaking in April when daytime temperatures often climb above +40 °C.
By May, the first signs of change appear, and by June, the rains arrive in full force. The wet season in Ам-Тимане lasts through September, bringing heavy downpours that transform the landscape. The heaviest rainfall usually falls in August, when the city receives over 270 mm of rain. Once October arrives, the rains taper off, and the dry season returns, cooling slightly but remaining warm.
Temperature
Temperatures in Ам-Тимане follow a predictable rhythm, with the hottest months falling just before the rains. In March and April, the mercury regularly rises to +41 °C during the day, while nights offer little relief, staying around +23...+25 °C. The heat can feel intense, especially under the unbroken sun, so midday breaks are common in local life.
Once the rains begin in June, temperatures drop noticeably. By July and August, daytime highs hover around +30...+32 °C, and nights cool to +21...+22 °C. The humidity rises during these months, making the air feel heavier, though the rain provides temporary respite from the heat. After the wet season ends, October and November bring a gradual return to warmer days, with temperatures settling between +35...+37 °C before the cooler dry season sets in.

The dry months from November to April see almost no rain at all—often less than 2 mm in total.

What to pack
What to pack for Ам-Тиман depends largely on the time of year. During the dry season, from November to April, lightweight, breathable clothing is essential to cope with the heat. Long sleeves and a wide-brimmed hat will help protect against the sun, while sunglasses and high-SPF sunscreen are must-haves. A scarf or shawl can also be useful for dust or cooler evenings.
For the rainy season, from June to September, waterproof footwear and a compact umbrella or rain jacket are practical additions. Quick-dry clothing is ideal, as humidity can make fabrics feel damp even when it’s not raining. Mosquito protection is also important during these months, so consider packing repellent and light, long-sleeved layers. Regardless of the season, comfortable walking shoes are a good idea for exploring Ам-Тиман on foot.
