When to Visit Madagascar

January brings the height of the wet season to Madagascar. On the highlands you feel it clearly. Warm days push to 26°C (79°F) and drop to around 17°C (63°F) at night. The month delivers its heaviest rainfall of the year, typically over 340mm on the plateau. Tropical cyclones are a genuine concern on the east coast and northern tip this month. Crowds are moderate rather than high since many travelers avoid the rains. Those who come find the forests at their densest and most alive.

February holds steady with highs around 26°C (79°F) and lows near 17°C (63°F), with heavy rainfall still, around 290mm. The worst of January's storms have usually passed by mid-month. The east coast remains potentially rough for travel. Some of the less-maintained roads inland can become impassable after sustained downpours. On the plateau, mornings can be clear and pleasant before afternoon storms build.

March sees Madagascar shifting toward the end of its wet season. Highs stay around 26°C (79°F) but rainfall drops noticeably to around 190mm. The countryside is intensely green, waterfalls are running full, and the mud on rural tracks is starting to dry. A good month for those who do not mind the occasional heavy afternoon shower but want to see the landscape at maximum greenness.

April is something of a transition month. Rainfall falls sharply to around 56mm, temperatures begin to ease with highs around 25°C (77°F) and nights dropping to a pleasant 15°C (59°F). The highland plateau starts to show its best face, with cool mornings, warm afternoons, and increasingly reliable blue skies. April tends to be underrated as a travel month in Madagascar and rewards those who notice.

May is comfortably into the dry season. Highs around 23°C (74°F) and nights cooling to 13°C (55°F) mean you will want a layer after dark on the plateau. Rainfall is minimal at around 18mm for the month. National parks are accessible, wildlife is active, and the tourist flow has not yet built to peak levels. A strong choice for independent travelers who prefer having the parks a little quieter.

June brings the high-altitude winter to Madagascar's central plateau in earnest. Daytime highs reach only 21°C (70°F) and nights drop to around 10°C (51°F), cool by any measure. Rainfall is essentially zero at around 5mm for the month. The northwest coast and Nosy Be, however, are at their best right now, with calm seas and clear days. The contrast between the cool highlands and the warm northwest is one of the more interesting features of Madagascar's geography and worth building into an itinerary if time allows.

July is peak dry season and the coolest month Madagascar typically offers. Highs of 20°C (69°F) and lows around 9°C (49°F) on the plateau mean evenings feel properly cold. Mornings can be brisk enough to warrant a proper jacket. Rainfall is negligible at around 8mm. July brings the island's highest visitor numbers, for lemur viewing in Andasibe-Mantadia and the national park circuits. Book accommodation well in advance.

August nudges up fractionally from July's low, with highs at 21°C (71°F) and lows around 10°C (50°F). Rainfall stays near zero at around 5mm. August holds much of July's visitor pressure as European summer holidays continue. The Tsingy de Bemaraha, Madagascar's extraordinary limestone pinnacle landscape, is accessible and rewarding in August. Dry conditions make the paths manageable rather than treacherous.

September sees Madagascar warming again as spring approaches in the southern hemisphere. Highs reach 24°C (75°F) and lows climb to 11°C (52°F). Rainfall ticks up slightly to around 10mm but remains firmly in dry-season territory. Crowds ease somewhat from the August peak. This is lemur breeding season in several parks, making wildlife sightings interesting and varied. Juveniles are visible and adults are conspicuously active. September often gets overlooked in favor of July and August. But it offers very similar conditions with thinner crowds.

October is the pre-wet-season warmup, with highs back up to 26°C (78°F) and lows at 13°C (56°F). Rainfall picks up to around 69mm. Still manageable. But the first real showers of the coming wet season start appearing in late October. The landscape begins to green up. An excellent month for those wanting warm weather without the full wet-season commitment. The first half of October is often reliable.

November moves Madagascar into wet season territory. Highs reach 27°C (80°F) and lows 15°C (59°F), with rainfall building to around 135mm. The east coast and north start to see more frequent heavy afternoon storms. The highland plateau remains reasonably accessible but you will encounter showers most days by month's end. A transitional month where timing within the month matters quite a bit. Early November tends to behave more like October, late November like December.

December sees the full wet season underway, with conditions moving toward January's peak. Highs around 27°C (80°F), lows 16°C (62°F), and substantial rainfall averaging around 310mm. Some rural roads in the east become difficult or impassable. The river crossings that are merely inconvenient in the dry season can become hazardous. The landscapes are dramatically lush, and for the right traveler the green season has a quiet appeal. Those relying on road transport in remote areas should factor in delays.
