Antananarivo sits at 1,280 meters above sea level, which means its tropical latitude comes with a temperate twist—expect springlike conditions year-round rather than the sweltering heat typical of lowland Madagascar.
The wet season delivers heavy afternoon downpours that can drench you in minutes, making waterproof layers and quick-drying fabrics essential from November through March.
Temperatures hover between 15°C and 26°C, with winter mornings occasionally dipping to 10°C—chilly enough that locals break out jumpers while tourists wonder if they packed for the wrong continent.
The high altitude keeps humidity manageable even during the wet months, though the thin air and intense UV radiation mean sunburn sneaks up faster than you'd expect.
Layering is the local religion here: mornings demand a jacket, midday sun forces you to strip down, and evenings require bundling up again as temperatures drop sharply after sunset.
Antananarivo follows a tropical wet-dry pattern rather than four seasons—think rainy summer and pleasant dry winter, but cooler than the tropics have any right to be.
