About Tamarin Bay

Tamarin Bay is a heavily documented, albeit temperamental, left-hand reef break situated on the western coast of Mauritius. The underlying bathymetry consists of a sharp, shallow, and highly structured coral reef shelf that dictates the wave's flawless peeling mechanics. As massive, long-period south-westerly groundswells approach from the Roaring Forties, they collide with this sudden transition in depth, jacking up into a thick, pitching lip. An easterly offshore trade wind actively grooms the face, ensuring the wave remains open and cylindrical. The wave features a steep, critical take-off that immediately drops the surfer into a high-speed, cavernous barrel section, followed by a long, racing wall. Due to the extreme shallowness of the live coral, the severe hydraulic force of the breaking wave, and the strong currents that pull across the reef, it presents a highly dangerous environment. Consequently, Tamarin Bay is strictly reserved for advanced and expert surfers who possess elite technical proficiency and extensive experience navigating heavy, hollow reef passes.

Frequently asked questions

How often is this page updated?

Current conditions refresh every 6 hours when the cron runs. Hourly data updates every 30 minutes. The 7-day forecast, luck factor, and packing notes are all pre-computed at the same time.

What is the luck factor?

We compare the 7-day forecast to the last 5 years of marine data for the same week at Tamarin Bay. The delta tells you whether conditions are shaping up better, worse, or about the same as a typical late April.

How is 'best session' picked?

We score each day of the 7-day forecast using the same algorithm as the leaderboard, and highlight the highest scorer.

Where does the data come from?

Open-Meteo's Marine API (swell height, period, water temperature) and Weather API (wind and conditions).

Does the score capture local knowledge?

Honestly, no. Every break has tide windows, swell directions and reef contours that a global model cannot see. Treat the score as a starting point, then check a local cam.
