Climate & Weather Guide in Mayotte

Climate zones, seasonal temperatures, rainfall patterns, and best travel times

Mayotte is a small Indian Ocean territory with a tropical maritime climate and very limited seasonal temperature variation. The island experiences a hot, humid wet season from roughly November to April and a cooler, drier season from May to October. Köppen classification for the main populated lowlands is tropical savanna (Aw), while local coastal and windward areas can feel more humid and rain-prone. For residents and expats, the climate is warm year-round, with sea breezes softening heat but humidity remaining noticeable much of the year. Rainfall is significant overall, and short, intense downpours are common in the wet season. The territory’s small size and island geography mean there is little climate diversity across regions.

Regional Climate Variations

Lowland Coastal Belt

This is the warmest and most settled part of Mayotte, including the main urban and coastal areas around Mamoudzou and Dzaoudzi. Conditions are typically tropical and humid, with small temperature differences between seasons and a strong marine influence. Rainfall is highest in the wet season, but sea breezes help make the heat more tolerable than inland. Köppen conditions here are mainly tropical savanna, with local variations depending on exposure to the monsoon flow and coastline orientation. Residents can expect warm nights, frequent humidity, and occasional heavy showers.

Summer:27-30°C

Winter:22-25°C

High rainfall

Warm, humid, and marine-influenced year-round, with the most comfortable feel during the cooler dry season.

Interior Hills and Central Uplands

The interior of Mayotte is slightly cooler than the coast because of elevation and more frequent cloud cover. These areas still remain tropical, but evenings can feel fresher and daytime heat is usually less intense than along the shoreline. Rainfall is often more pronounced on windward slopes, especially during the wet season, which supports dense vegetation and a greener landscape. For residents, this zone can feel more comfortable than the lowlands, though humidity remains significant and heavy rain can arrive quickly during the monsoon months.

Summer:26-29°C

Winter:21-24°C

Very high rainfall

Slightly cooler and greener than the coast, with more frequent rain on exposed slopes and a softer heat profile.

Mayotte has a consistently warm tropical climate with a pronounced wet season and a drier, slightly cooler season. For residents and expats, the main appeal is the year-round warmth and maritime setting, while the main adjustment is managing humidity, heavy seasonal rain, and cyclone risk during the wet months.
