What to expectMamoudzou through the year

Mamoudzou changes little through the year. Average daily highs stay between 26 and 28 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 353 days a year reach 25 °C, 3 of them reach 30 °C. The warmest reading in the 1991–2020 record is 31 °C, in March.

Rain is strongly seasonal. January averages 234 mm against 12 mm in July — 19 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Mamoudzou is warmest in March at 30 °C and coldest in August at 26 °C. Sea temperature lags the air by a month or two, which is why late summer swims warmer than early summer at the same air temperature.
