The monthly mean temperature is lowest in July, at 14.0 °C, and reaches its highest monthly mean in December, at 20.5 °C. The mean across the monthly figures is 18.0 °C.

Sunshine duration can help with broad outdoor-planning expectations, but it is not the same as day length and does not guarantee sunshine throughout a day.
Best Travel Time Guide for Antananarivo, Madagascar: Ideal Seasons and Weather Insights
For visitors prioritising lower average rainfall, September is a conditional option: its mean daily rainfall is 0.16 mm/day. That average does not guarantee dry weather or indicate how many days receive rain, so keep plans flexible and bring suitable rain protection. Rain preparation is especially relevant in January, when mean daily rainfall reaches 11.32 mm/day. If cooler monthly averages are your priority, consider July, when the monthly mean temperature is 14.0 °C; this is not a forecast of daytime highs, so prepare for variation during a visit. For daylight outdoor planning, mean daily sunshine is highest in November at 10.99 hours/day, and lowest in July at 8.76 hours/day.
