When you’re planning a trip to Antananarivo, the weather really shapes your whole experience. The city sits up on Madagascar’s central plateau, so it’s cooler than the coast, but the seasons still change things up.
The best time to visit Antananarivo is during the dry season from April to October. Days stay mild, skies are clearer, and rain is a lot less likely to mess with your plans.
During these months, you can wander through historic landmarks, lively markets, or nearby parks without heavy rain or muddy streets getting in your way.
The cooler air makes walking those hilly city streets feel a lot more doable, and dry weather means easier trips out to surrounding attractions.
Once you leave the dry season behind, things heat up and get wetter. Humidity climbs, and you’ll probably run into frequent downpours that sometimes cause flooding or travel headaches.
If you know the seasonal patterns, it’s easier to pick when to go and what to expect when you arrive.
Best Time to Visit Antananarivo for Ideal Weather
Antananarivo’s spot in the highlands gives it a cooler vibe than Madagascar’s coast. The most comfortable months have mild temperatures, not much humidity, and clear skies—perfect for exploring the city or heading out into the countryside.
Rainfall patterns really make or break the travel experience here.
Overview of Optimal Months
If you’re aiming for the best weather, visit Antananarivo from April through October, during the dry season. Rain barely shows up, skies stay sunny, and daily highs usually sit between 20°C and 25°C (68°F–77°F).
Cooler days and crisp evenings? July and August are your friends. Overnight lows sometimes drop near 9°C (48°F), so tossing a light jacket in your bag is smart.
These months are fantastic for walking tours or checking out landmarks like the Royal Hill of Ambohimanga.
On the other hand, November to March brings higher humidity and frequent showers. The city turns lush and green, but heavy rain can throw a wrench in outdoor plans.
Roads get muddy, and rural adventures aren’t as predictable.
Why the Dry Season Is Preferred
You’ll get the most out of Antananarivo in the dry season. Roads stay passable, and outdoor attractions don’t get shut down by surprise storms.
If you’re mixing city sightseeing with trips out to nearby reserves, reliable weather is a huge plus.
Humidity drops, so walking the city’s hills feels easier. The air clears up, and you’ll get those classic views of red-tiled rooftops and rice fields.
Cultural events line up with the dry months too. Independence Day in June brings parades and fireworks, and Donia Festival in May fills the streets with music and dance. These local celebrations make your trip a bit more special, and you won’t have to dodge rain to enjoy them.
Weather Highlights During Peak Months
During peak season, the climate barely throws any surprises. Daytime highs usually stick between 20°C and 25°C, and the sun’s out more often than not.
Rainfall drops to less than 30 mm per month in the core dry months.
July and August cool things down, with highs closer to 20°C and chilly nights—ideal if you like mild weather for hiking or wandering markets.
By September and October, things warm up a bit, averaging 23°C–26°C, but skies still stay mostly clear. Honestly, these months hit a sweet spot: warm but not too hot, with hardly any rain before the wet season rolls back in.
Understanding Antananarivo’s Climate
Antananarivo’s weather feels different from the coast because of its highland location and tropical plateau climate. You’ll notice two clear seasons: wet and dry. Temperatures stay moderate, so it’s not as hot as other parts of Madagascar.
Climate Classification and Location
Antananarivo sits right in central Madagascar, about 1,200 meters (3,900 feet) above sea level. That elevation keeps things cooler than the lowlands or coast.
The city falls under a subtropical highland climate. This means you get mild temperatures, a rainy season, and a long dry stretch. Extreme heat almost never happens here.
Rainfall follows a strong seasonal pattern. The rainy season runs from November to March, with heavy downpours. The dry season lasts from April to October, bringing clearer skies and little rain.
Thanks to this mix, Antananarivo offers a more temperate climate than other parts of Madagascar, which can get hot, muggy, or super wet depending on where you go.
Temperature Patterns Throughout the Year
Temperatures in Antananarivo stay pretty moderate. Average highs run from 20°C in July up to about 28°C in November.
Nights get cooler, dropping to around 10°C in the coldest months and about 17°C in the warmest ones.
You won’t need to worry about freezing, but evenings can feel chilly, especially with the altitude. Packing some light layers is always a good idea.
The hottest stretch usually lands right before the rains hit in November. The coolest period is mid-year, from June to August, when mornings and evenings cool off but you can still enjoy outdoor activities.
All in all, Antananarivo stays pleasant. You don’t get the wild swings in temperature you’ll find in other tropical capitals.
Humidity and Sunshine Trends
Humidity in Antananarivo stays on the higher side, but it changes with the seasons. January and February get the muggiest, peaking around 80%. October feels better, with humidity dropping closer to 69%.
Sunshine hours go up and down too. October brings about 8 hours of sun a day, while February drops to around 6 hours because of more clouds.
The dry season means clearer skies and more daylight, which makes planning outdoor stuff easier. Even in the wet season, you’ll get breaks of sunshine between showers.
So, whether you’re chasing sun or want to avoid humidity, timing your trip can make a big difference.

What to Expect When Visiting During Different Seasons
Antananarivo’s two main seasons shape your visit: there’s a cooler, drier stretch with blue skies, and a warmer, wetter period with higher humidity and frequent rainfall.
Each season changes not just the weather, but how you get around and what you can comfortably do outside.
Travel Experience in the Dry Season
The dry season lasts from April to October. Daytime temperatures usually land between 17–27°C (63–81°F), and nights can cool off to 9–15°C (48–59°F).
You’ll notice lower humidity, clearer skies, and more sunshine than in the wet months.
This is hands-down the best time to visit Antananarivo if you want to spend long days strolling through historic districts, open markets, or the beautiful highland landscapes nearby.
Roads are easier to travel, since heavy rains won’t slow you down.
Expect 6–8 hours of sun per day, making sightseeing much more enjoyable. Evenings can get chilly, especially in June and July, so bring a few layers or a light jacket.
Tourism picks up in this season. Hotels and attractions might be a bit busier, especially in July and August, but you’ll also find more cultural events and festivals happening—much easier to enjoy when the weather’s on your side.
Travel Experience in the Wet Season
The wet season runs from November to March. You’ll notice frequent, sometimes heavy rain, especially in January when totals hit 200–300 mm. Humidity usually sits above 75–80%, so the air feels warmer than the actual 23–30°C (73–86°F).
The city and countryside burst into a deep, vibrant green. Rice paddies and hillsides look stunning, but all that rain might keep you indoors more than you’d like.
Afternoon showers show up often. Sometimes, rain just doesn’t let up all day.
Flooding or muddy roads can slow down travel between regions. Inside Antananarivo, expect delays, and don’t forget to bring rain gear like a waterproof jacket or umbrella.
If you’re not set on outdoor adventures, you can still check out museums, indoor markets, and cultural shows. Fewer tourists come during the wet season, so you’ll probably find better hotel deals and less crowded spots.
Travel Tips for Weather-Related Planning
When you plan a trip to Antananarivo, the weather really shapes what you pack and which activities make sense. Temperatures, rainfall, and humidity all shift with the seasons, so packing smart means you’ll stay comfortable and enjoy more of your time.
Packing Recommendations by Season
From April to October, Antananarivo enjoys its dry season. Days feel mild, with highs from 20°C to 26°C, and nights can dip near 10°C in July and August. Pack light layers, a warm jacket for chilly evenings, and comfortable walking shoes. Sunglasses and sunscreen help too, since skies usually stay clear.
During November to March, expect heavy rains, especially in January and February. Bring a lightweight rain jacket, umbrella, and water-resistant shoes. Roads get muddy, so go for tough, durable footwear. Quick-dry clothes make life easier when humidity climbs.
A small daypack comes in handy year-round for water and essentials. If you want to explore rural areas outside Antananarivo, pack for cooler nights and less predictable shelter—a compact travel blanket or extra sweater can save the day.
| Season | Key Items to Pack |
|---|---|
| Dry (Apr–Oct) | Jacket, layers, sunscreen, walking shoes |
| Wet (Nov–Mar) | Rain gear, waterproof shoes, light clothing |
| Year-round | Daypack, hat, reusable water bottle |
Weather-Related Considerations for Activities
Dry months work best if you’re into walking tours, markets, and historic sites in Antananarivo. Roads usually stay in better shape, and you can actually get to those outdoor spots without too much hassle.
People who love wildlife excursions outside the city will probably find clearer trails and fewer floods during this time. It’s just less of a headache, honestly.
Once the wet season rolls in, cultural visits like museums, local workshops, or indoor performances make way more sense. Heavy rain often messes with road travel, so you’ll want to give yourself extra time if you’re venturing beyond the capital.
Humidity in summer can really drain your energy on long hikes. Try to get outside in the morning when it’s still cool.
July and August bring cooler evenings, so you might need to rethink any plans for nighttime events. Without the right layers, it gets surprisingly chilly.
If you’re traveling during those in-between months, you’ll probably get a bit of everything. Toss a light rain jacket and some sun protection in your bag, just in case the weather decides to switch things up.
