The Lowdown
Alright crew, Rusty here. Let’s be honest – this 16-day window is looking like a total write-off. We’ve only got one spot to talk about, and it’s not giving us a thing to smile about.
North Moana Beach is the only game in town, and it’s a sad one. The water temp is 57°, which is pretty normal for the season, so no surprises there.
We’re looking at a massive dry spell. From Wednesday the 12th all the way through to the 20th, it’s flat and crap. Over a week of nothing. On the 12th, we get a 5ft swell from the WSW, but it’s a short-period 6-second windswell with a 15 mph cross-on breeze. The combined energy is a weak 124, and it’s all choppy and poor. Don’t even bother.
The 13th drops to 1ft, and the wind is straight onshore. The 14th goes glassy in the morning, but the swell is a pathetic 1ft. The combined energy is down to 14. It’s a flat spell, pure and simple.
We finally see a pulse on Friday the 21st of August. A 4ft swell from the W with a 6-second period shows up, with a cross-shore wind from the N at 9 mph. The combined energy climbs to 77, but it’s still labeled poor surf conditions. It’s a small, bumpy mess.
On Sunday the 23rd, the afternoon brings a 4ft NNW swell, but it’s onshore wind and short period. No good.
The most “interesting” day, if you can call it that, is Monday the 24th of August. The swell hits 6ft from the W, with a 6-second period, and the combined energy is 245 (moderate). But you’ve got a fresh cross-shore wind at 19 mph from the NNW. That’s lumpy, cross-chop, and ugly. At 6ft, it’s expert-only territory, and the conditions are more suited for kitesurfing than paddling in.
The rest of the window into the 27th fades back to tiny, weak swell, with 0.7ft and 3ft bumps. There’s no standout. No clean, glassy day with a proper groundswell. This whole 16-day run is a bust for North Moana. It’s one of those stretches where the ocean is just taking a nap. Forecasts can flip, but right now, I’d leave the board in the garage.
Rusty.

A general guide to surfing at North Moana Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for North Moana Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
