The Lowdown
Alright, surfers, Rusty here. Let’s break down what’s happening on the water for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. The forecast is looking pretty grim for North Moana Beach. We’ve got a real dry spell on our hands with no real surf to speak of for the entire 16-day period. The first recommendation doesn't appear until Saturday, August 8th, but it’s a non-starter.
From Saturday the 8th through the following week, we’re looking at a mix of weak, wind-chopped slop and tiny dribblers. The swell energy is low, with the "combined energy" sitting at just 13 (very weak) on the 8th, and even when it bumps up to 261 on Monday the 10th, it’s accompanied by a fresh cross-onshore wind that’ll ruin any chance of a clean wave. The swell is mostly short-period windswell, under 8 seconds, making it all mush and no push.
The water temp is sitting at 57°, which is about 1° below normal, so pretty average for this time of year. Nothing to write home about there.
We do get a few days of glassy or clean conditions, like on Saturday the 15th and Sunday the 16th, but the swell is laughable at 0.7 ft or less. Even with that nice glassy surface, there’s nothing to ride. The long period groundswell that shows up on the 17th and 18th (14-15 seconds) would be a dream at a point break, but here at North Moana Beach, it’s only producing 0.3 ft waves. That’s not surf, that’s a lake.
The only standout, if you can even call it that, is maybe the late afternoon on Monday, August 17th, when we get a completely glassy ocean and a 14-second pulse from the SW. But with a wave height of 0.3 ft, you’d need a toy boat to get a ride. It’s a tease of potential, but the reality is there’s no surfable energy.
This is one of those blank runs that’s more normal for the area. The wind is often against us, and the swell doesn’t align. It’s a quiet period, plain and simple. Forecasts can change, and we might get a surprise, but based on what’s on the table right now, leave the boards in the car and maybe go for a paddle if you’re desperate.
Rusty.

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.
