ii) The central Sahel region is hot and subtropical, with a wet season from May to November which normally brings over 350mm of rain and in some places much more. iii) In the south, rainfall is higher and on average, regions receive over 1,000mm. Temperatures in the capital NâDjamena, in the southwestern region of the country, average around 24Â°C in January and 33Â°C in May.
