Quick answer
Madagascar has a clear wet season (roughly November–April) and a dry season (roughly May–October), but conditions vary strongly by region. The east and north are tropical and wettest from November to March; the central highlands (Antananarivo) are warm and rainy in summer with cool dry winters; the west and south are drier, with the south being semi-arid year-round. Cyclone risk peaks January–March. Expect warm, humid coastal weather and cooler nights in the highlands; road conditions and domestic flights can be affected in the wet season.
Key points
- Wet season: November–April (peak rain and cyclone risk January–March).
- Dry season: May–October (best road access and most reliable weather).
- East and north: tropical, heaviest rains in summer; central highlands: cooler nights.
- South and south-west: generally the driest and sunniest regions.
- Plan flexibly in the wet season; MadagascarPrivateTours.com arranges practical local alternatives if needed.
Regional overview (short)
Madagascar’s weather must be read regionally: the east coast (Toamasina and rainforests) receives the most consistent rainfall; the central highlands (including Antananarivo) are cooler with distinct dry winters; the west and south-west have a pronounced dry season and are warmer; the far south is semi-arid. Cyclones mainly affect the east coast and north-east between January and March.
Month-by-month guide (practical, region-focused)
- January: Peak wet season. Heavy rain across the east and north; humid on the coasts; central highlands warm and rainy. Cyclone season active—expect possible road and flight disruption.
- February: Very wet and the highest cyclone risk. Many interior tracks and smaller roads can be difficult; some national park approaches may be affected.
- March: Still wet but rainfall often decreases late in the month. Cyclones can occur; plan more flexible schedules and allow extra time between destinations.
- April: Rain eases. East and north still humid with afternoon showers; landscapes are lush and rivers high but access improves compared with mid-summer.
- May: Start of the dry season. Cooler nights in the highlands and much better road conditions. Good month for travel transitions and fewer tourists.
- June: Cool and dry — very reliable weather countrywide for travel, trekking and wildlife watching; mornings can be chilly in the highlands.
- July: Coolest month in the central highlands, dry and sunny elsewhere. Coastal areas are comfortable and humidity is lower.
- August: Still dry and often sunny. Temperatures start to rise slightly; this is a high season for travel with stable conditions.
- September: Dry and warming. Good conditions for visiting most parks; roadside dust can increase in very dry areas of the south and west.
- October: Warming and still mainly dry; occasional early showers may appear at the end of the month, particularly in the north and east.
- November: Rain returns gradually, first in the east and north. Increasing humidity; some afternoon storms begin to appear. Transition month—good for birding and floral activity.
- December: Wet season resumes. Hotter and more humid, especially on the coasts; cyclone risk begins to rise towards the end of the month into January.
