Where to Go in Madagascar in December

Northern & Northwest

Diego-Suarez, Nosy Be, Ankarana

By December the north is well into its wet season; long, warm rains punctuate the days and cyclone alerts are possible later in the month. Coastal resorts at times suspend excursions and some remote reserves restrict access after heavy storms; coral visibility declines but marine life remains active for resilient divers. Travel here in December means planning for rain, carrying strong waterproofs, and leaving room for travel-day delays.

East Coast & Rainforests

Toamasina/Tamatave, Andasibe, Ranomafana

Rain frequency peaks again in December across the east: long, warm downpours, cloudbursts and very humid air are common, and cyclone formation becomes a possibility as the month progresses. Toamasina’s port and smaller harbours can see shipping disruptions, and national parks occasionally close tracks when rivers overflow. Travel here requires waterproof luggage, patience for delays, and expectations of lush rainforest scenery at the cost of convenience.

Central Highlands

Antananarivo, Antsirabe, Fianarantsoa, RN7

December is a warm, wet month with frequent heavy afternoon storms and a humid feel across the highlands; rivers swell quickly and some low-lying areas near river valleys flood temporarily. City life becomes more punctuated by rain interruptions and intercity buses may run slower; the benefit for visitors is verdant scenery and fewer crowds. Pack waterproofs, good boots and expect longer transfer times when planning holiday itineraries.

West Coast & Tsingy

Morondava, Tsingy de Bemaraha, Mahajanga

By December the west is in the early wet season: warm, humid, and prone to sudden downpours-coastal towns become lusher but access to deeper Tsingy areas can be patchy after heavy events. Ferry crossings match the rhythm of the rains and schedules are less predictable; if you’re island-hopping or moving between reserves, expect delays and have contingency nights booked.

South & Southwest

Toliara/Tuléar, Ifaty, Isalo, spiny forest

December tends to be hotter and more humid with more frequent showers toward month’s end as the rainy season begins; flash flooding in low-lying coastal areas can happen after heavy cells. The southwest’s famed landscapes feel lush briefly after initial rains, and some river pools refill, but accessibility to remote tracks can start to decline. Travellers should carry waterproofs and be prepared for occasional road delays.

Offshore Isles & Sainte-Marie

Île Sainte-Marie, small outer islands

December moves into the wetter, storm-prone half of the year with warm temperatures, higher humidity, and an increasing chance of cyclonic activity by month’s end. Ferry services to the mainland may be curtailed in strong weather; some guesthouses operate a reduced schedule when storms threaten. Travelers should plan for flexibility, strong rain protection, and the occasional rearranged boat transfer.
