The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Nipussi (Nyang-Nyang). This is a solid reef break that’s got a good, consistent pulse going through the forecast period, but the conditions are going to keep you on your toes.
The story starts with a decent sized, long-period S swell rolling in. The combined energy is strong, hitting 2428 (moderate to strong wave energy). The water is sitting at 85°, which is about average for this time of year, so nothing unusual there. The catch is the wind. We’ve got a persistent onshore breeze from the SSE, which is going to put a bit of a bump on the surface. The swell is solid, around 7 ft, but with that wind, it’s going to be a bit of a battle. It’s a real shame because there’s plenty of power in the water.
Wednesday morning sees that 7 ft S swell with a very long 16-second period, but the SSE wind is on it. The afternoon is similar, dropping a touch to 7 ft but still holding that long period. Thursday morning brings a risk of thunderstorms, with the swell settling to 6 ft. The period drops a bit to 14 seconds, but the energy is still there. By Thursday afternoon, the period jumps back up to 18 seconds, which is proper groundswell. That’s a classic sign of better shaped waves, but it also means longer lulls between sets. The wind remains onshore, unfortunately.
Friday morning sees a slight improvement with the wind easing to a light cross-onshore breeze from the SE. The swell is a clean 7 ft. The afternoon looks better with the wind nearly glassing off, but the swell kicks up a little to 8 ft. That’s a window worth watching.
The weekend is a bit of a mixed bag. Saturday and Sunday are plagued by the risk of thunderstorms and light cross-onshore winds. The swell size drops off, hanging around 5 ft to 6 ft, and the period shortens. The energy is moderate, but the quality is just not there. It’s a bit disappointing after the mid-week action.
Now, if you’ve got some patience, things get interesting heading into the second week. Monday the 18th through to the end of the forecast period sees a new SSW swell building. The real standout is Wednesday the 19th of August. We’re looking at a solid 10 ft SSW swell with a 18-second period, and the combined energy is massive, hitting 5290 (very strong wave energy). The wind is onshore, but the power is undeniable. This is a big, powerful swell. For the advanced surfers only, this is going to be a serious session. Anything over 8 ft is expert territory, and this is 10 ft. The Thursday the 20th holds similar size, and the Monday the 24th also looks punchy with a 8 ft SSW swell.
For the absolute best of the bunch, I’d be looking at the 19th of August. The sheer size and power (10 ft, 18-second period, 5290 combined energy) is the highlight of the whole 16-day window. It’s a big, deep-water groundswell that this reef will handle. The wind is a bit of a downer, but for that kind of power, it’s worth the paddle. It’s a long-range call, so it’s promising but not a lock. The Monday the 24th is a close second with similar size and a slightly cleaner wind forecast, but the 19th has the edge on raw power.
Remember, this is a reef break, so it’s for advanced crew only. And with crowds noted as “sometimes,” you might have a few others in the water, but the size should keep the numbers down.
Alright, that’s the picture from Nipussi. Keep your eyes on the 19th and 24th. Stay safe out there.
Rusty.
