March weather forecast
Reunion

March in Reunion signifies the tail-end of the austral summer, with temperatures starting to decrease slightly. Coastal areas experience average temperatures from 24°C (75.2°F) to 29°C (84.2°F), while temperatures in the highlands range from 18°C (64.4°F) to 22°C (71.6°F).

Saint-Denis and Saint-Pierre, two significant urban areas, follow similar temperature patterns, although they may be marginally warmer due to the urban heat island effect. Even as the temperatures begin to drop, the humidity levels remain high, contributing to a sense of persistent warmth.

March is also the closing month of the cyclone season. Although the likelihood of cyclones decreases as the month progresses, early March can still see these intense weather events, characterized by substantial rainfall and high wind speeds. The eastern coast and the mountains continue to receive the bulk of the rainfall, ranging between 250mm (9.84") to 400mm (15.75"). The western coast, sheltered by the island's topography, typically receives less precipitation.

As the island transitions from March to April, there's a notable shift in weather patterns. April sees a further reduction in temperatures and a significant drop in rainfall as the island moves from the wet summer months towards the cooler and drier winter season.
