Best Time to Visit Réunion — Seasonal Guide 2026
Réunion Island doesn't fit the standard tropical mould. While its Indian Ocean neighbours sell themselves on endless summer, Réunion's dramatic topography — a 3,000-metre volcano, three colossal cirques, and a coastline split between wet east and dry west — means there's no single "perfect" time to visit. The right season depends entirely on what you want to do. This guide breaks it down, month by month, so you can plan your trip around the experiences that matter to you.
Réunion's Climate at a Glance
Réunion has a tropical climate with two distinct seasons: a dry, cool season from May to November (austral winter) and a hot, wet season from December to April (austral summer). But that's an oversimplification. The island's east coast — exposed to trade winds — can receive over 4,000mm of rain annually, while the sheltered west coast (where most beach hotels sit) gets less than 700mm. Up in the cirques, temperatures can drop below 5°C at night even in summer, while sea-level stays balmy year-round.
Dry Season: May to November
🌤️ May–November Overview
The dry season is Réunion's peak tourist period — and for good reason. Clear skies, comfortable temperatures, and minimal rainfall make this the ideal window for hiking, volcano viewing, and outdoor exploration. The trade winds keep humidity low, especially on the west coast around Saint-Gilles-les-Bains. This is also whale-watching season: humpback whales migrate past the island from June to October, often breaching within sight of the beach.
May & June — The Sweet Spot Begins
May marks the transition from the wet season and is arguably the most underrated month to visit. The landscape is still gorgeously green from summer rains, but the weather has dried out enough for comfortable hiking. June brings cooler nights — you'll want a jumper in Cilaos or Salazie — but the coastal strip stays perfect for beach days. Hotel prices haven't yet hit their July–August peak, making this a savvy choice for budget-conscious travellers. The first humpback whales usually appear off the west coast in early June.
July & August — Peak Season
These are the busiest months, driven by French school holidays. The weather is at its most reliable: sunny, dry, and cool enough for strenuous hiking without overheating. The Piton de la Fournaise trail is in prime condition, and the cirques offer crystal-clear visibility across enormous distances. Whale watching reaches its height — boat tours from Saint-Gilles-les-Bains report near-daily sightings. The downside? Hotel rates peak, popular gîtes book out months in advance, and you'll share the trails with more company. Book early if you're visiting in July or August, and consider using IMPT to secure sustainable accommodation at the same price as anywhere else, with the bonus of carbon removal built in.
September & October — The Goldilocks Months
If we had to pick the single best window for visiting Réunion, it would be September through October. The weather remains excellent, whale watching is still going strong, and the summer crowds have thinned. Hiking conditions are sublime — warm enough for shorts during the day, cooler for sleeping, and rarely a drop of rain. The Cirque de Mafate trails are at their most accessible, and you stand a good chance of having viewpoints almost to yourself on weekdays. Hotel prices moderate after the August peak, and IMPT's 5% cashback means every night you book effectively pays you back in tokens.
November — The Transition
November is the shoulder month. Temperatures begin climbing back towards summer levels, and the first rains of the wet season can arrive, particularly on the east coast. It's still a fine time to visit — especially the first half of the month — and you'll benefit from lower accommodation rates before the December holiday surge. The jacaranda trees in Saint-Denis and the highland towns explode into purple bloom during November, a photographer's dream against the green mountain backdrop.
Wet Season: December to April
🌧️ December–April Overview
The wet season means heat, humidity, and the possibility of tropical cyclones (most likely January through March). But it also means Réunion at its most lush, with waterfalls thundering at full power and the forests alive with colour. If you're not here primarily for multi-day hiking and you don't mind afternoon downpours, the wet season offers genuine advantages: lower prices, fewer tourists, and a landscape that feels almost impossibly green.
December — Festive Season
December straddles the seasonal divide. Early December can still be quite dry, but by Christmas the rains are usually settling in. The island buzzes with festive energy: Réunionnais Christmas markets, midnight Mass in Creole, and elaborate family feasts featuring smoked pork, spiced duck, and mountains of samosas. Hotel rates spike during the Christmas–New Year period as French mainlanders arrive for tropical family holidays. If you want December without the eye-watering prices, aim for the first two weeks of the month.
January to March — Cyclone Season & Low Prices
These are the wettest, hottest months — and the ones most travellers avoid. Cyclones, though not annual, are a real possibility, and heavy rainfall can close hiking trails and make the volcano road impassable. But here's the contrarian case: Réunion's cyclone-warning system is world-class, major storms are forecast days in advance, and the chances of your entire trip being washed out are low. What you get in return are the year's lowest hotel prices, near-empty trails on dry days, and a landscape so intensely green it looks Photoshopped. The Trou de Fer waterfall is at its most spectacular, and the mangoes and lychees are in season — cheap, abundant, and deliriously good.
If you do visit during cyclone season, base yourself on the sheltered west coast (Saint-Gilles-les-Bains, Boucan Canot, La Saline) where rainfall is dramatically lower than the east. Keep your plans flexible, and check Météo-France Réunion's excellent weather service daily.
April — The Turn
April is the mirror of November — a shoulder month where the wet season begins its retreat. Rainfall tapers off, humidity drops, and the hiking trails start drying out. It's a wonderful time for photographers: the landscape retains its wet-season lushness but the light grows clearer by the week. Hotel prices remain low, and you'll have the cirques largely to yourself. The only real gamble is whether you catch the tail end of the rains or the start of the dry — but that's a risk worth taking at April's prices.

Festivals & Events in 2026
Timing your visit around a festival can transform a good trip into an unforgettable one. Here are Réunion's cultural highlights:
- Chinese New Year (February) — Lion dances, firecrackers, and street feasts in Saint-Denis and Saint-Pierre's Chinatown districts. Réunion's Chinese community has shaped the island's culture for over 150 years.
- Tamil Fire-Walking Ceremonies (January–February) — One of the most extraordinary cultural events in the Indian Ocean. Devotees walk barefoot across burning embers at temples across the island, a centuries-old tradition brought by Tamil indentured labourers.
- Grand Raid (Diagonale des Fous) (October) — The "Diagonal of Fools" is one of the world's toughest ultra-marathons, a 165km race across the island's mountainous spine. Even if you're not running, the atmosphere across Réunion is electric during race week.
- Fête de la Musique (21 June) — Free music everywhere: maloya (the island's traditional blues-like chant), séga dance rhythms, and modern Creole hip-hop filling the streets.
- 20 December (Abolition of Slavery Day) — A deeply significant public holiday commemorating the abolition of slavery on Réunion in 1848, marked by ceremonies, concerts, and the maloya music that was born from the island's painful history.

Packing Tips by Season
Dry season (May–November): Light layers are essential. Pack shorts and t-shirts for the coast, but bring a fleece, waterproof jacket, and long trousers for the highlands. A warm hat and gloves aren't overkill for sunrise at Piton de la Fournaise or early mornings in Cilaos. Sturdy hiking boots are mandatory if you're tackling the cirques. Reef-safe sunscreen and a wide-brimmed hat for the lagoon.
Wet season (December–April): Quick-dry clothing is your friend. A proper rain jacket (not just a windbreaker), waterproof hiking boots, and a dry bag for electronics. Insect repellent with DEET is essential — mosquitoes are more active. Pack a lightweight sweater for air-conditioned restaurants and the occasional cool highland evening. And bring appetite: mango and lychee season demands your full attention.
Questions Fréquentes
What is the best month to visit Réunion Island?
September and October are widely considered the best months to visit Réunion. The weather is dry and warm, hiking conditions are excellent across all three cirques, whale-watching is at its peak (August–September), and crowds are moderate after the July–August holiday season but before the December rush. Coastal temperatures hover around 25°C, while the highlands sit at a crisp but comfortable 12–18°C during the day.
Does Réunion Island have a rainy season?
Yes, Réunion's rainy season runs from December to April. This period brings higher humidity, afternoon tropical downpours, and the statistical possibility of cyclones (most likely between January and March). However, Réunion's microclimates mean the west coast — where most tourist infrastructure sits — receives dramatically less rain than the east. The rainy season is also when the island is at its most photogenic, with waterfalls in full spate and the forests an almost luminous green. If you're flexible with plans and don't mind the odd downpour, you can travel very affordably during these months.
Can you visit Piton de la Fournaise all year round?
Yes, Piton de la Fournaise is accessible year-round via the well-maintained road to Pas de Bellecombe, but visibility varies dramatically. The dry season (May–November) offers the best chance of clear summit views. During the wet season, the volcano is frequently shrouded in cloud, though you can still hike the caldera floor. The volcano erupts unpredictably — sometimes several times a year — and during active phases, access to the crater rim may be restricted for safety. Always check current conditions at the Maison du Volcan museum in Bourg-Murat, which provides real-time eruption updates and trail status information. The museum itself is excellent and worth a visit regardless of whether you can reach the summit.
