What is the weather like in Mauritius in January?

January weather summary

January is midsummer in Mauritius. The island sits in the southern hemisphere, so its warmest months are December through March. January is typically the hottest month of the year.

Temperature

Daytime temperatures average 30–33°C in coastal areas, reaching 35°C or higher during heatwaves in sheltered locations. Humidity is high — often 80–90% — making the heat feel more intense. Nights remain warm at 25–27°C. The central plateau (Curepipe, Vacoas) is consistently 4–5°C cooler than the coast.

Rainfall

January is one of the wettest months of the year, particularly on the east coast and central plateau which receive more rainfall than the west and north. Rain typically falls in heavy but short afternoon thunderstorms rather than prolonged grey days. The west coast (Tamarin, Flic en Flac, Le Morne) remains notably drier and is a better choice for January visitors.

Cyclones

January is at the heart of the cyclone season, which runs from November to April. Mauritius issues cyclone warnings at four class levels. Most storms pass at a distance and cause some wind and rain rather than direct landfall. However, a tropical storm can disrupt a visit with heavy rain and rough seas for two to three days at a time. Travel insurance that covers weather disruption and activity cancellation is advisable.

Sea conditions

The sea is warm in January — approximately 28°C — and clear. However, trade winds and storm swells can make the east coast choppy. The west-facing lagoons at Flic en Flac and Le Morne are calmer. Diving visibility can be reduced by plankton and river runoff after heavy rain.

Is January a good time to visit?

January works well for beach holidays on the west coast and for anyone who enjoys warm weather and doesn't mind the possibility of a day or two of rain. It is not ideal for kite-surfing, outdoor activities requiring sustained good weather, or anyone sensitive to heat and humidity.
