You can travel to Madagascar year-round by understanding the climate you'll encounter in each region. Madagascar experiences highly varied climatic conditions depending on the region, season, and altitude. In most of the country, the dry season (April to October) alternates distinctly with the rainy season (November to March).

• Traveling during the rainy season, off-peak, is a fantastic experience as nature is extraordinary and rural life is in full swing. Rain often falls in the late afternoon, and it's warm.
• The coasts of the Mozambique Channel (west) are bathed in sunshine and heat.
• Rainfall falls regularly on the East Coast (Indian Ocean), eastern slopes (rainforests) and the northern tip of the island.
• Located beneath the Tropic of Capricorn, the southwestern regions of Madagascar are very arid.
• On the Central Highlands, during the dry season, average daytime temperatures hover around 20°C. In Antananarivo, situated at 1,300 meters altitude, and across the Highlands, nighttime temperatures can drop to 0°C in July–August.

In summary, keep in mind:

• On the East Coast and Sainte-Marie, monsoon rains are frequent in June and July.
• On the Highlands, evenings are cool. In July–August (austral winter), it's cold.
• When camping, bring a fleece and down jacket for evenings at altitude.
• Cyclones form in the Indian Ocean between January and March, sometimes striking the East Coast, the northern tip, and more rarely the southern tip and West Coast.
• Central Highlands. Central Madagascar experiences a marked alternation between dry and rainy seasons. Heat is tempered by altitude during the dry season. Nights can be particularly cool. Many visitors are surprised by the cool conditions in the evenings and nights in Antananarivo and surrounding areas in July and August.
• Eastern Madagascar and the Indian Ocean. This is the wettest (and therefore most verdant) region of the island. Beyond the rainy season, which brings evening showers from November to March, rainfall can be abundant between June and late August, particularly on Sainte-Marie Island. September and October are the driest months.
• Northern Madagascar. Dry and wet seasons are well-defined, but precipitation is lighter than on the East Coast. Trade winds can be strong around Diego Suarez between June and October. Nosy Be experiences a marked rainy season.
• Western regions and the Mozambique Channel. Dry and wet seasons are pronounced, but rainfall is very limited and heat often high. The rainy season lasts approximately from November to February.
• Southern and far southern regions. Semi-arid climate. Precipitation is minimal and the dry season long and scorching. Sparse rains fall during a few short weeks in December and January.
