Water Temperature in Reunion: General Trends and Swimming Opportunities

Réunion, a French overseas department in the Indian Ocean, is known for its stunning volcanic landscapes and beautiful coastline. The sea temperature around the island remains relatively warm throughout the year, typically ranging from 23°C (73°F) in the cooler months of July and August to 28°C (82°F) in the summer months from December to February. This makes the waters ideal for swimming and enjoying the ocean almost all year long.

The island’s beaches, such as those in Saint-Gilles-les-Bains and L'Ermitage, offer calm waters perfect for swimming, especially on the west coast, where the lagoons are protected by coral reefs. These areas are popular for families and those looking for relaxed beach days. Réunion is also famous for its crystal-clear waters, providing excellent conditions for snorkeling and diving. The coral reefs surrounding the island are teeming with marine life, making it a fantastic destination for underwater exploration.

For the more adventurous, Réunion also offers opportunities for water sports like surfing, windsurfing, and kitesurfing, particularly along the island’s more exposed eastern and southern coasts. While the beaches on the south and west sides are often calmer, the rugged cliffs and dramatic landscapes add an adventurous flair to the experience.

Reunion Weather

Réunion has a tropical climate with warm temperatures throughout the year, influenced by its location in the Indian Ocean. The coastal areas typically experience temperatures ranging from 72–90°F (22–32°C), while the higher elevations in the interior are cooler, with temperatures sometimes dropping to 50°F (10°C) or lower at night. The island has two main seasons: a hot and rainy season from November to April and a cooler, drier season from May to October. During the wet season, tropical cyclones can occur, bringing heavy rainfall and strong winds, especially along the windward east coast.

The drier season is generally more pleasant, with lower humidity and milder temperatures, making it the preferred time for outdoor activities. However, due to the island’s mountainous terrain, climate conditions can vary significantly within short distances. The eastern side of Réunion receives more rainfall, while the western coast tends to be sunnier and drier. In the highlands, temperatures can be much cooler, especially at night, creating microclimates across different regions. This diverse climate supports a rich variety of landscapes, from lush rainforests and waterfalls to volcanic peaks and dry savannas.
