The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for us. It’s looking like a promising stretch ahead, but patience is the name of the game for the next couple of days. We’ve got a solid run of surf coming, especially for the more experienced crew.
We kick things off with the first real opportunity on Friday morning the 11th at Riviere Noire Harbour. The water’s sitting at a warm 76°, which is a touch warmer than normal for this time of year – feels nice. The swell is a clean 5 ft from the south with a solid 12-second period, and with the wind out of the east at 12 mph, it’s slightly offshore. This is clean, moderate wave energy (1088), but it’s just the warm-up. The real standout arrives early on Saturday the 12th. Saturday morning is where it’s at: a solid 6 ft of south swell rolling in with a very long 15-second period, and the wind is a gentle offshore breeze from the east at 9 mph. This is going to be clean, powerful, and for the experienced surfer only. The energy is strong (1430). This sandbar setup will love that long-period groundswell, offering up some proper shape. Keep in mind, with a period that long, it might be a touch straight at the take-off, so pick your peak wisely. Crowds are possible here, but with the quality on offer, it’s worth the company.
Sunday the 13th keeps the goods coming. Morning has clear skies, a light offshore from the southeast at 6 mph, and a chunky 6 ft SSW swell with an impressive 18-second period. The combined energy is very strong (2220). This is expert territory again – big, clean, and powerful. Sunday afternoon holds up well, but the wind fades to a slight cross-offshore.
Monday the 14th sees a drop in quality. The swell backs off a touch, the wind picks up to a moderate cross-offshore, and we’re looking at marginal conditions. The energy is moderate (940-1231). It’s a day to sleep in or check the tide.
By Tuesday the 15th, the wind is howling from the southeast at 25 mph in the morning. That’s a strong offshore – it’ll be clean but a serious battle to paddle into. The swell is only 4 ft with a long 18-second period, but the energy is still strong (1755). This one is for the hardcore only, or maybe the kite surfers if the sandbar setup looks fun.
Wednesday the 16th is a big call for the brave. We’ve got an 8 ft south swell in the morning with a 15-second period, building to 10 ft in the afternoon. The energy is massive (4724 and 4119). The wind is a fresh offshore from the east-southeast. This is a serious, heavy, expert-only day. The setup is more interesting for kite surfing than paddle surfing unless you’ve got the quiver and the nerve.
Things settle down but stay fun into the next week. Thursday the 17th afternoon is a nice turn with 7 ft south swell, 13-second period, and moderate offshore wind. That’s clean, powerful, and very surfable.
We hit a classic “Rusty special” on Monday the 21st. It’s a week and a half out, so keep an eye on it, but the forecast has the wind going glassy from the southeast at 3 mph in the morning, with a 4 ft SW swell at 13 seconds. This will be peaky, clean, and a joy on a log or a fish. The energy is moderate (514).
Then, looking at Tuesday the 22nd (11 days away – a promising long-range call), we might see the best conditions of the whole run. The morning is glassy calm with east-northeast wind at 0 mph, and a 5 ft SSW groundswell with an 18-second period. The combined energy is very strong (2061). This is the full package: a long-period swell at a sandbar, zero wind – the waves will be perfect and lined up. Expect a crowd for this one.
Wednesday the 23rd keeps the run alive with 8 ft SSW swell in the morning and light offshore winds. Again, expert territory, but the quality is there.
After that, the swell dips and the wind freshens through the 24th and 25th. But don’t write off Saturday the 26th (15 days out). The forecast is showing 8 ft SSW swell with a 16-second period and a moderate offshore. The energy is massive (3596). If it holds, that’s a big, powerful, and clean day for the charger crew. A proper long-range standout to keep on the radar.
Overall, the best bets are Saturday the 12th morning and that glassy Tuesday the 22nd morning. The 12th is solid and reliable, the 22nd is the glassy dream. The big stuff on the 16th and 26th is for experts only.
Stay safe, pick your sessions, and I’ll see you out there.
Rusty.
