Reunion Weather: Climate, Seasons, and the Best Time to Visit
Réunion is a French island in the Indian Ocean, roughly 700 kilometres east of Madagascar. Despite its modest size, the island packs an extraordinary range of climates into one place — a consequence of its dramatic volcanic topography, which rises to more than 3,000 metres at Piton des Neiges. From the sun-drenched western coast to the perpetually misty eastern highlands, understanding Réunion's weather means understanding its terrain first.
Two Seasons, One Island
Réunion follows a classic tropical rhythm with two distinct seasons. The hot, wet season runs roughly from November through April. During these months the island sits in the path of the Indian Ocean monsoon, bringing heavy rainfall, high humidity, and occasionally powerful tropical cyclones. January and February are statistically the most active for cyclones and the wettest overall — serious enough that travellers planning outdoor activities should monitor forecasts closely. The Saint-Denis weather page gives you live conditions for the capital right through cyclone season.
The cool, dry season spans May to October. Temperatures ease noticeably, trade winds pick up from the southeast, and rainfall on the western and southern coasts drops sharply. This is when Réunion is most comfortable for hiking, beach days, and exploring the caldera. July and August are the coolest months, and while the coast stays pleasant, higher elevations such as the Cirque de Cilaos can dip close to freezing at night.
Geographic Variation Across the Island
The east coast — and in particular the windward slopes — receives the bulk of the island's rainfall year-round, making areas around Saint-André genuinely lush and green. The west coast, in the rain shadow of the central massif, is considerably drier and sunnier. Saint-Paul weather on the northwest coast reflects this drier pattern, making it a favourite base for beach tourism even during the shoulder months.
The south of the island sits between these two extremes. Saint-Pierre weather tends to be warmer and sunnier than the highlands but wetter than the far northwest. Further inland, the town of Le Tampon sits at altitude, giving it noticeably cooler and cloudier conditions than the coast — check the Le Tampon weather forecast before heading up if you plan to use it as a base for crater walks.
Best Time to Visit Réunion for Weather
For most visitors, May through October offers the best combination of manageable temperatures, low cyclone risk, and reliable sunshine on the western and southern coasts. June and September are particularly popular: the trade winds keep things fresh, the sea is calm enough for diving and snorkelling, and trails through the UNESCO-listed interior are in their best condition. If your priority is seeing the island in full tropical bloom — waterfalls at full flow and the volcano most dramatic — a visit in March or April after the main cyclone risk has passed can be rewarding, though you should be prepared for rain.
FAQ
What is the best time to visit Réunion?
May to October is widely considered the best time to visit. The dry season brings lower humidity, cooler and more stable temperatures on the coast, minimal cyclone risk, and excellent conditions for hiking. June through September hits the sweet spot between comfort and accessibility for outdoor activities.
What is the climate of Réunion?
Réunion has a tropical climate with two main seasons: a hot, wet season from November to April and a cooler, drier season from May to October. Climate varies dramatically with elevation and aspect — the eastern windward coast is much wetter than the western leeward coast, and highland areas are far cooler than sea level.
Does Réunion get cyclones?
Yes. Réunion lies in the South Indian Ocean cyclone belt, and tropical cyclones are a real risk between approximately November and April, with January and February being the most active months. The island has robust alert systems, but travellers visiting during this period should monitor official warnings and have flexible plans.
