Antananarivo (Madagascar) weather in October

October closes the dry season here, and regulars are careful with the packing advice: bring something long-sleeved for the evenings, but do not overdo the warm clothes - nothing heavy is needed. Our row shows why both halves of that hold: 28.3C by day against 13.8C at night, a fourteen-degree fall that belongs to the altitude rather than the season. Rain is still light at 24.8mm across 4.6 days, though they warn it arrives in earnest towards the end of the month, so a late-October trip is racing it. The landscape is green by now and this is one of the better months for wildlife. The record: humidity 66 percent, 10.9 hours of sun, a 16.2 kph wind and AQI 41.

Regulars are consistent this counts among the cooler, drier months here, part of the dry season running from May through October, with this specific city named as one of the coldest spots in the country alongside Antsirabe and Fianarantsoa at this elevation. Our row backs that cool, genuinely dry read, 21.6C over 9.6C nights feeling 7C, with rain essentially absent, 5.5mm across under a day, and humidity at 76 percent. Regulars are specific a warm layer, a cardigan or fleece, is genuinely useful for this month despite Madagascar's tropical reputation, mornings and evenings running cool enough to need it. This remains a genuinely comfortable, low-humidity stretch for overland travel and outdoor activities. The record: 8.3 hours of sun, an 18.2 kph wind and one of the cleanest air readings in this project, AQI 30.

June is the month regulars pick for value rather than for perfection: popular but not peak, so prices stay low and the crowds thin. They are precise that the only genuinely cold part of Madagascar is the central plateau, and they name this city among the coldest places on it - upper 60s to low 70s by day and upper 40s to low 50s at night, which is our row to the degree at 22.4C over 10.5C. Rainfall is falling away but the technical dry season has not quite arrived, so expect sporadic showers between bright spells; ours is 13.1mm across 2.3 days. The record: humidity 77 percent, 8.6 hours of sun, a 17 kph wind and AQI 37.

May opens Madagascar's dry season, which runs to October, and regulars call May and June the shoulder: comfortable weather, lower prices, and no real need to book hotels ahead - a rare thing to be able to say about any month in this collection. The local caveat is about altitude. The only part of the country that genuinely gets cold is the central plateau, and Antananarivo sits on it; our row's 24.5C day falling to 12.9C at night is that, comfortable by day and properly cool after dark. The other trade-off is wildlife: May starts to cool and some creatures become less active. Rain has largely stopped at 6.4mm across 2.1 precipitation days, though regulars note the old patterns have become less reliable. The record: humidity 78 percent, 9 hours of sun, a 16 kph wind and AQI 39.

August is mid-winter in Madagascar's highlands, and the Madagascar forum keeps correcting the same assumption: the coast is sunny and hot, but around Antananarivo it is genuinely cool, and July and August are the coolest months of the year. They are also the busiest, on European school holidays, with the popular parks full. The trade-off worth weighing is wildlife - this is when animals show themselves least, with reptiles and the smaller lemurs hibernating through the cold months, so a trip built around lemurs is better later in the year. What August does deliver is settled weather across the April-to-October season. The record for Tana: 23.5C days against 10.1C nights, one precipitation day in the month, 9.3 hours of sun and AQI 28.
