Climate & when to go
Because of the high mountains, Réunion’s climate varies more than that of Mauritius. It still, however, experiences only two distinct seasons: the hot, rainy summer from December to April and the cool, dry winter from late April to October. The east coast is considerably wetter than the west, but wettest of all are the mountains above the east coast – around Takamaka, Plaine-des-Palmistesand the northern and eastern slopes of the volcano. As with Mauritius, the cyclone season is roughly December to March.
Temperatures on the coast average 22°C during winter and 27°C in summer. In the mountains, they drop to 11°C and 18°C respectively. Clouds generally cover the peaks and high plains from mid-morning. The drier winter months are the most favourable for hiking.
The peak tourist seasons are during the French school holidays from late June to early September. From October through to the New Year holidays is also reasonably busy, but after this everything eases down during cyclone-prone February and March. The weather normally changes for the better in April, which isn’t a bad time to a visit.
