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

Saint-Denis is located on the north coast. The south coast of Réunion tends to be windier, especially in the Dry season. 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.
