What to Wear & Take to Antananarivo in September:

For tops, we suggest wearing thin and quick-dry cotton T-shirts, short-sleeved shirts, or blouses. As for the bottom clothing,
sweatpants and long skirts are both fine. But if you’ve planned a tour to the rainforests, cuffed pants may be your best choice. For shoes, flat scandals or sneakers are wise options. After the sunset, put on a trench coat or change into knitwear or a hoodie to keep you from catching a cold. Wearing a thin silk scarf is also wise to deal with the windy weather in September.  
 

You also need to take mosquito spray, especially when you go into the rainforests. Even though September is in the dry season, it still rains from time to time, so it’s also necessary to take an umbrella or a raincoat. Besides, sunscreen and sunglasses are also helpful when you sightsee under the strong sunlight of Antananarivo.
