Despite its small size, Réunion experiences quite a diverse climate throughout the year and across the island. This is due to several factors, including its position on the Indian Ocean, and the mountainous landscape in the island’s interior. The summer months (December, January, and February) boast hot temperatures of above 90°F, sometimes reaching above 100°F. The months of November and March also experience hot temperatures with highs of 80s (°F).

The winter months (June through to August), and the months leading into and out of this season, are much more comfortable than summer. Temperatures generally fall to between 75°F and 85°F, making it warm enough to swim, but cool enough to be comfortable when hiking throughout the island. However, tourists need to bring warm clothing when they visit in the winter, as night time temperatures can drop to below 60°F.

Réunion is renowned for its high rainfall; it usually receives several meters a year, making it one of the wettest destinations in the world. Most of the rain falls during the summer months, with the eastern region of the island experiencing the most precipitation across the year. The period between November and March gets the most rainfall, especially when tropical storms pass through the island.

Best Time to Visit Réunion

The best months to visit Réunion are between April and September. If traveling between November and March, expect high levels of rainfall and a hot and humid climate. The trade winds off the Indian Ocean allow the temperatures to fall during Réunion’s winter season. This means tourists can still enjoy the beaches, swimming, and the sites, without the sweltering heat. Of course, the high tourist season also falls during this time, so accommodation and transportation is significantly higher.

Visiting during the summer months is not advised, as high temperatures and high rainfall make it somewhat uncomfortable. Nevertheless, the months of September, October, and March generally boast cooler temperatures and less rainfall than the summer months. In addition, the peak tourist season is seen as finished, so prices tend to fall.
