December Weather in Madagascar
Is December Right for You?
Advantages
- Lush landscapes at their absolute greenest - waterfalls are spectacular after months of rain, and the rainforests in Ranomafana and Andasibe are dense with life. Photography is incredible if you time it between storms
- Lemur babies everywhere - December is peak breeding season for many species, so you'll see mothers carrying tiny infants in parks like Andasibe and Isalo. Guides know exactly where to find them
- Significantly fewer tourists than June-September - you'll have trails and lodges mostly to yourself, which means better wildlife encounters and more attention from guides. Prices at mid-range hotels drop 20-30% compared to dry season
- Humpback whales still visible off Île Sainte-Marie through mid-December - the tail end of whale season means fewer boats and more intimate encounters before they migrate south
Considerations
- Heavy rain makes many roads impassable - Route Nationale 5 to Maroantsetra often closes, and even major routes like RN7 can take twice as long. Four-wheel drive is non-negotiable, and some parks like Tsingy de Bemaraha are completely inaccessible
- Cyclone season begins - December marks the start of cyclone activity, with storms possible from late December onward. While direct hits are rare, heavy rain bands can disrupt travel plans for 3-5 days at a time. Travel insurance with weather coverage is essential
- Beach conditions are rough on the east coast - Île Sainte-Marie and Masoala get pounded with rain and wind, making snorkeling murky and boat transfers uncomfortable. The west coast around Morondava is slightly better but still unpredictable
Best Activities in December
Andasibe-Mantadia National Park rainforest walks
December rain brings the forest alive - you'll hear the indri's haunting calls echoing through mist-covered canopy, and guides spot chameleons, frogs, and leaf-tailed geckos that are active in wet conditions. Early morning walks from 6-9am happen before the heaviest afternoon rain. The 3 km (1.9 mile) Indri Circuit is manageable even in mud with proper boots. Lemur activity peaks in December with babies clinging to mothers.
Ranomafana thermal springs and rainforest treks
The natural hot springs at Ranomafana are perfect after muddy morning treks in 24°C (75°F) rain. December is ideal for spotting the rare golden bamboo lemur - they're active feeding on bamboo shoots that sprout after November rains. The 6 km (3.7 mile) Vohiparara circuit takes 4-5 hours and requires decent fitness on slippery trails. You'll need a head torch for night walks to spot mouse lemurs and chameleons - December humidity brings them out.
Antananarivo markets and cultural sites
When afternoon rains hit around 2-4pm, Tana's covered markets are perfect refuges. Analakely Market sprawls under corrugated roofs where you'll find vanilla, raffia baskets, and zebu horn crafts at 30-40% below tourist shop prices. The Rova palace complex offers panoramic views between rain showers - go early at 8am before clouds roll in. December is mango season, so street vendors sell massive piles for 2,000-3,000 MGA (0.50 USD) each.
Isalo National Park canyon hiking
Isalo's sandstone formations create natural drainage, so trails are walkable even after December rains - unlike northern parks that turn to mud. The 8 km (5 mile) Piscine Naturelle trail takes 4-5 hours and ends at a crystal-clear swimming hole fed by waterfalls. December heat makes the cool water perfect after hiking. You'll spot ring-tailed lemurs and sifakas in the canyon forests. Start at 6am to finish before midday heat peaks at 32°C (90°F).
Avenue of the Baobabs photography sessions
December's dramatic storm clouds create incredible golden-hour light at the Avenue of the Baobabs near Morondava. The west coast gets less rain than the east, so you'll have better odds of clear sunset shots around 6pm. Go at sunrise (5:30am) for even better light with fewer tour groups. The avenue is just 260 m (853 ft) of dirt road lined with 800-year-old baobabs - you can walk it in 10 minutes but photographers spend hours here.
Île Sainte-Marie whale watching (early December only)
Humpback whales linger off Île Sainte-Marie through mid-December before migrating south. Early December (first 10 days) offers calmer seas and fewer boats than peak season. You'll see breaching, tail slaps, and occasionally mothers with calves. Boats go out 8-11am before afternoon winds pick up. The 2-3 hour trips cover 15-20 km (9-12 miles) offshore. That said, late December gets too rough - waves reach 2-3 m (6-10 ft) and visibility drops.
December Events & Festivals
Alahamady Be (Malagasy New Year preparations)
Late December sees families preparing for Alahamady Be, the traditional Malagasy New Year that falls in March but requires months of preparation. You'll see increased activity in markets as people buy new clothes and plan family gatherings. It's not a tourist event, but you'll notice the cultural significance if you're staying with local families or visiting villages. Markets get busier and prices for zebu meat rise slightly.
