The Two Seasons at a Glance

Dry Season (May-November)

• Cooler temperatures
• Low humidity, clear skies
• Strong trade winds (especially June-August)
• Best for most activities — especially the Emerald Sea

Wet Season (December-April)

• Higher temperatures and humidity
• Occasional heavy rain
• Cyclone risk January-February
• Lower prices, fewer tourists

Month-by-Month Breakdown

January-February: Hot, Humid, Cyclone Risk

Peak wet season with intense humidity and cyclone risk that can disrupt flights into Arrachart Airport. Best only for budget-flexible travelers. Not recommended for structured itineraries.

March-April: Transition to Stability

Rain eases, landscapes become lush — especially in Montagne d’Ambre National Park. Good for nature lovers and photographers seeking green scenery. Occasional rain still possible.

May-June: Dry Season Begins

Temperatures drop, humidity decreases, skies clear. Trade winds begin strengthening along the coast. Excellent for sightseeing and early-season travel with fewer crowds than peak months.

Whatever month you visit, book your Emerald Sea and Three Bays tours in advance on GetYourGuide — they sell out during peak season.

July-August: Prime Conditions

One of the best periods overall. Stable, sunny weather with low humidity. Strong, consistent winds make this the prime kite surfing season at Baie des Sakalava. Excellent water clarity for Emerald Sea excursions.

September-October: The Sweet Spot

Many experienced travelers consider this the absolute best time to visit. Conditions combine warm but not excessive temperatures, stable weather, and slightly reduced winds. Perfect for photography, beach relaxation, and inland exploration including Tsingy Rouge. Peak demand — book accommodation early.

September-October hotels in Diego Suarez fill fast — check availability on Agoda now.

November: Shoulder Season Value

Temperatures begin rising but heavy rains haven’t fully returned. Fewer tourists, competitive pricing, generally good weather. Best for value-focused travelers avoiding peak-season crowds.

December: Heat Returns

Conditions become less predictable as the wet season establishes itself. Still possible to travel but requires flexibility.
