The Lowdown

Yo, what's up, it's Rusty. Let's get straight into it.

Right off the bat, we’ve got a mixed bag on the horizon. The first few days are a bit underwhelming with small, short-period swell and a moderate breeze—definitely not worth paddling out for. But hang tight, because this forecast shapes up into a proper solid run of swell, especially for the more experienced crew. The standout window is from around Saturday the 23rd into the following week, where the combo of size, clean winds, and solid southerly groundswell is looking like the pick of the period.

We’re looking at Riviere Noire Harbour (Mauritius), a sandbar setup that’s fairly consistent. The water temperature is sitting at a touch warmer than normal for this time of year at 77°, so you won't need the thick steamer.

Starting off, Tuesday the 18th and Wednesday the 19th are pretty forgettable. Tuesday morning has 4 ft swell from the south with a 12-second period, but it’s cross-offshore wind at 16 mph and the wave energy is weak (694). Thursday the 20th is cleaner with gentle offshore breezes, but the swell drops right down to 3 ft on the morning and then 2 ft on the afternoon—that afternoon pulse does show a nice 17-second period from the SW (376), but it's tiny. Not worth rushing for.

Friday the 21st starts to wake up. The afternoon sees 4 ft from the SSW with a 14-second period, clean conditions with light offshore ESE wind at 6 mph, and a decent moderate combined wave energy of 751. It’s a decent warm-up.

Saturday the 22nd is when things start getting interesting. Morning has 5 ft from the SW at 14 seconds, gentle offshore ESE breeze at 9 mph, and the combined energy jumps to 882. By the afternoon, it’s 6 ft from the SSW, same 14-second period, light offshore wind, and energy up to 990. Clean, building, and looking like a solid intermediate day.

Now, Sunday the 23rd is the first true standout. We’re talking 7 ft from the SSW with a 14-second period, and the combined energy rockets up to 2001. The wind is cross-off from the east at 9 mph, so it’ll be clean. This is in the expert zone—over 8 ft is for experienced surfers only. If you’ve got the skills, this is the day to circle in red.

Monday the 24th keeps the quality high with 6 ft from the SSW in the morning (13 seconds, energy 1537) and 4 ft in the afternoon but with a longer 15-second period and light offshore wind (energy 1447). Excellent conditions across the board.

The run continues through Tuesday the 25th with 7 ft from the SSW on the afternoon, gentle offshore wind, and energy at 1670—another excellent session for experienced surfers.

Wednesday the 26th is the big one. Morning brings 10 ft from the SSW with a 16-second period (very long groundswell), light offshore SE wind at 6 mph, and combined energy of 5026. This is pure power. Afternoon is similar at 10 ft, 15-second period, energy 3818. This is a serious groundswell event; best handled by experts, and at a sandbar, it should peel nicely with those long periods.

Thursday the 27th gets wild but messy. Morning is 13 ft from the south with 11-second period, cross-off south wind at 16 mph (energy 6560). The afternoon is massive—20 ft from the south, 15-second period, but with a strong SSE breeze at 28 mph and energy at 28,500. That’s too big for this break, and the wind is howling. This is more of a kite-surfing setup than paddle surfing. Keep the board in the car.

Friday the 28th through the weekend stays in the 8 ft to 12 ft range with fresh offshore winds, but the energy levels stay high (2000-7000+). It’s still clean but more on the challenging side with the breeze.

Monday the 1st of September into Tuesday the 2nd brings another strong pulse. Tuesday the 2nd has 6 ft from the SSW with an 18-second period in the morning (energy 2746) and 7 ft from the SW with a 17-second period in the afternoon (energy 2938). That’s a very long period groundswell with moderate offshore breeze, excellent for experienced surfers.

Crowds at Riviere Noire Harbour can show up sometimes, so get out early on the standout days.

To sum it up: the best of the best is Sunday the 23rd, Wednesday the 26th, and Tuesday the 2nd of September. Mark your calendar for that epic 10 ft+ day on the 26th—it’ll be worth the wait. For now, save your energy and your wax.

Rusty.
