Riviere du mat Surf Spot Guide, Reunion Island

Nestled on Reunion Island's wild east coast, Riviere du Mat is a rare rivermouth gem that delivers powerful right and left handers peeling across a sandy bottom peppered with rocks. This spot pulses with a raw, untamed vibe, offering fun, punchy waves that reward experienced surfers seeking uncrowded sessions in a dramatic volcanic landscape. It's the kind of place where the surf feels alive with the island's intense energy, perfect for those chasing quality over quantity.

Geography and Nature

Riviere du Mat sits on the rugged east coast near Saint-Andre, where the mighty Rivière du Mât river meets the Indian Ocean amid lush cane fields and towering volcanic cliffs. The area feels remote yet accessible, framed by the green Cirque de Salazie highlands, with a black sand beach scarred by river outflows and occasional rocky outcrops. Sugar factories dot the nearby flats, blending industrial heritage with the primal coastal scenery that defines this windward side of the island.

Surf Setup

This rivermouth setup fires up right and left handers, often forming punchy A-frames or walled faces with barrel potential on bigger swells. Optimal swells come from the southeast at 1.5 to 3 meters, while northeast trades provide the cleanest offshore angles, turning choppy seas into glassy walls. Mid to high tide is prime to avoid shallow rock exposures, and a typical session delivers 4 to 8 powerful rides per hour when it turns on, blending speed and drive for airs and carves.

Consistency and Best Time

Surf at Riviere du Mat is inconsistent due to the east coast's exposure to persistent trades, breaking best from April to September during the cyclone window when southeast swells pulse through. Avoid December to March when summer flats dominate and river runoff muddies the lineup. Early mornings in the dry season offer the highest odds of clean, powerful sets up to 2.5 meters.

Crowd Levels

The spot stays empty on weekdays and weekends alike, with mostly local surfers sharing the lineup in a peaceful vibe. Tourists rarely venture here, keeping sessions spacious.

Who It's For

Riviere du Mat suits experienced surfers who can handle powerful waves and rocky sections. Beginners should steer clear due to the heavy water and fast takeoffs, while intermediates might snag fun shoulders on smaller days. Advanced riders thrive on the speed and punch, linking sections with progressive maneuvers.

Hazards to Respect

Watch for strong rips feeding off the rivermouth, especially after rain, and scattered rocks that demand precise positioning. Sharks are a noted risk on Reunion's east coast, so surf in groups and heed any local advisories.

Water Temperature and Wetsuit Guide

Summer from December to March brings warm waters of 24 to 27 degrees Celsius, where boardshorts or a 2/2 mm shorty suffice for comfort. Winter from June to October cools to 20 to 23 degrees Celsius, calling for a 3/2 mm fullsuit on chillier swells. Spring and fall hover at 22 to 25 degrees Celsius, making a spring suit ideal for extended sessions.

How to Get There

Fly into Roland Garros Airport (RUN) just 25 kilometers north near Saint-Denis, then drive south on the coastal road through Saint-Andre for about 20 kilometers to the rivermouth—look for cane fields and the river bridge. Free roadside parking lines the beach access, a short 200-meter walk over sandy paths. No public transport serves the spot directly, so renting a car is essential for flexibility.
