The climate in Réunion Island is one of the most fascinating aspects of this Indian Ocean island. With its diverse landscapes, ranging from sunny beaches to mountainous peaks, the island offers a surprising climatic variety that influences not only the daily lives of locals but also the experiences of visitors. Understanding the climate of Réunion Island is essential for planning an optimal stay, tailored to your preferred activities and expectations.
General Characteristics of the Climate in Réunion
Réunion has a tropical climate divided into two main seasons: the wet season, or southern summer, and the dry season, or southern winter. However, due to its unique topography, the climate can vary significantly from one region to another.
1. The Wet Season: Heat and Tropical Rains
The wet season in Réunion extends from December to April. During this period, the island experiences high temperatures, often around 30°C on the coasts, accompanied by heavy rains. These downpours, although sometimes intense, are often short-lived and quickly give way to sunshine. This season is also when the island may be affected by tropical cyclones, which can bring extreme weather conditions.
2. The Dry Season: Coolness and Sunny Days
The dry season, which extends from May to November, is characterized by cooler temperatures and drier conditions. This is the ideal time for outdoor activities such as hiking, trekking, and exploring volcanic landscapes. Temperatures range from 20 to 25°C on the coasts, while the highlands can experience much lower temperatures, especially at night.
Climatic Variations by Region in Réunion Island
The climate of Réunion Island varies not only by season but also by altitude and geographic location. Here’s an overview of the island’s main climatic zones.
1. Leeward Coasts: A Drier Climate
The leeward coasts, located on the west side of the island, are generally drier than other regions. Towns like Saint-Gilles and Saint-Leu benefit from generous sunshine year-round, with relatively low rainfall. This area is perfect for beach activities, diving, and relaxation.
2. Windward Coasts: More Rain, More Greenery
The windward coasts, primarily on the east side of the island, are wetter due to the trade winds. Towns like Saint-Benoît and Saint-André receive more frequent rain, which explains the lush vegetation in this part of the island. These conditions create an environment conducive to agriculture and exploring tropical forests.
3. The Highlands: Coolness and Microclimates
The highlands of Réunion, which include mountainous areas and cirques like Cilaos, Mafate, and Salazie, are known for their microclimates. The altitude greatly influences temperatures, which can drop below 10°C in winter and even approach 0°C in the highest areas, such as Piton des Neiges. Rainfall is also more frequent here, especially in the cirque of Salazie, known as one of the wettest places on the island.
How Does the Climate Influence Activities in Réunion?
The climate in Réunion plays a crucial role in the choice of activities on the island. Here’s how to adapt your plans based on the seasons and climatic conditions.
1. Outdoor Activities: Hiking and Exploration
The dry season is ideal for hiking and exploration. Cooler temperatures make long walks more enjoyable, and dry weather ensures walkable trails. It’s also the perfect time to climb Piton de la Fournaise, one of the most active volcanoes in the world, or explore the lava tunnels.
2. Diving and Water Activities: Enjoying the Lagoons
The wet season, although warmer, is excellent for water activities. The water temperature is pleasant, and the protected lagoons allow for diving, snorkeling, or simply relaxing on the beaches. However, it’s important to monitor cyclone alerts during this time.
3. Cultural Discoveries and Village Visits
Regardless of the season, Réunion offers a wealth of cultural experiences year-round. The moderate temperatures in the highlands allow visits to villages like Hell-Bourg or Cilaos, known for their Creole charm and artisanal traditions. Festivals and cultural events, spread throughout the year, are also a great way to immerse yourself in the local culture.
Tips for Planning Your Trip According to Réunion’s Climate

Before setting out on a hike or planning an outing, always check the local weather forecast. Conditions can change quickly, especially in the mountains, so it’s best to be well-informed to avoid surprises.
2. Adapt Your Wardrobe to the Microclimates
Given the island’s climatic diversity, it’s advisable to bring a range of clothing. Pack light clothes for the coast and warmer attire for the highlands. A rain jacket or windbreaker is also essential.
3. Be Flexible During Cyclone Season
If you’re traveling during cyclone season, make sure you have a backup plan in case of adverse weather conditions. Some activities may be canceled or postponed, but Réunion always offers interesting alternatives.
