Tamarin Bay Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s get into it.

Alright, so we’ve got a long stretch of 16 days here, but it’s not all showtime. The first windows of proper surf kick off from Saturday, 22 August, and run through to Sunday, 30 August, with a clear standout session tucked in the middle. After that, things drop right off—there’s a big gap from Monday, 31 August, all the way through to Thursday, 3 September, with nothing worth paddling out for. Then a faint pulse returns on Friday, 4 September, but it’s thin and winds are messy. So, the real action is in that first week and a half.

Let’s talk about Tamarin Bay (Mauritius). This is a reef break that’s inconsistent, so it’s not always on, but when it fires, it’s a gem. The water here is sitting at 76.5°, which is a touch warmer than normal for this time of year—nothing wild, but it’s a nice little bonus.

Saturday morning, 22 August, starts off with a 4.6 ft SW swell, period 14 seconds, and moderate energy (708). The wind is cross from the east at 15 km/h, so there’s a bit of chop on the surface, and the tide might be a factor. It’s not the cleanest, but it’s a start. By Saturday afternoon, the wind drops to 5 km/h from the SE, shifting to cross-off, and the swell bumps up to 4.9 ft from the SSW, period still 14 seconds. The energy climbs to 857, and the conditions clean right up. This is a solid afternoon session for the advanced crew.

Sunday, 23 August, rolls in with a bigger SSW swell at 7.5 ft, period 15 seconds, and energy jumping to 2178. Morning has a cross wind from the east at 10 km/h, so there’s a bit of ripple. But Sunday afternoon is the real gem of the early run: glassy conditions, 7.2 ft SSW swell, 14-second period, and energy sitting at 1997. The wind is virtually nothing—just 5 km/h from the ESE, glassy as can be. For a reef break that lines up with the optimum SW swell direction, this is top-tier. Cleanish, punchy, and long-period groundswell energy. This is the first standout.

Monday, 24 August, keeps the size up: 7.5 ft in the morning, 7.9 ft in the afternoon, both from the SSW, with periods around 14–15 seconds. Energy is strong (2324 and 2505). The morning’s a bit cross, but the afternoon turns glassy again with that ESE breeze at 5 km/h. Another excellent window for the experienced surfer.

Tuesday, 25 August, the swell starts to ease a little—6.2 ft in the morning, clean with cross-off wind, but by afternoon, light rain moves in and the wind turns cross-on, dropping the quality. The standout is definitely the morning.

Now, the big one. Thursday, 27 August. This is the heavy-hitter day. Morning kicks in with a 8.2 ft SSW swell, 19-second period—that’s very long-period groundswell—and energy is a massive 4399. Wind is a light SSE at 5 km/h, cross-off, clean. This is expert territory. That afternoon, the swell hits 9.8 ft, period 18 seconds, energy 5074, and the wind is a gentle 15 km/h cross-off. Still clean. This is a serious session, but it’s only for the advanced—anyone else, stay on the beach.

Friday, 28 August, pushes the limit: 14.8 ft in the morning, 13.1 ft in the afternoon, both from the SSW, periods 17 seconds, energy readings of 10089 and 9460. That’s very strong wave energy. The wind is cross-off, clean, but at 20–35 km/h, it’s a fresh breeze. This is big, powerful, and not for the faint-hearted. The afternoon is a bit more manageable, but still expert-only. The setup here is more interesting for kite surfing than paddle surfing if you’re not a charging expert.

Saturday, 29 August, stays big—13.1 ft all day, period 16
