Saint-Denis' climate compared to the rest of the country

The eastern region sees the highest rainfall and the mountainous interior of Réunion is much colder than the coast; expect an average low in winter of 4°C/39°F and a high of 15°C/59°F.

Dry Season May to November – Winter

Although it is mostly dry, it can still rain anytime. It is very warm on the coast but the humidity is lower than in the Wet season.

  • May & June – It’s about 27°C/81°F during the day, but nights are cooler at about 19°C/66°.
  • July, August, September & October – These are the driest months, but you still need to be prepared for rain when heading out in the mountains. Daytime is lovely at about 25°C/77°F.
  • November – It warms up and the average daytime temperature is 28°C/82°F. It starts to rain more regularly.
