The Lowdown
Right, let’s break this down for the imperials, because I know some of you think in feet and miles.
Same story, long, quiet stretch ahead at North Moana Beach. For about nine days—through the morning of September 20—you’re looking at small, weak surf. Wave heights barely nudge 2-3 ft, and the wind is mostly rubbish: onshore, cross-onshore, or blowing too hard for the tiny waves to hold any shape. The combined wave energy is in the single or low double digits (19, 15, 11), which is the ocean snoozing. Different wind directions come through—NNE, WSW, even S—but none of them work with the break’s preferred WSW swell.
The one standout to wait for is Sunday morning, September 20. That morning we get a clean 7 ft swell from the west, with a period of 7 seconds. It’s short-period, so it’ll be a little steeper and faster, but the wind is glassy—an SSE breeze at just 5 mph. The water will be flat clean. Combined wave energy hits 388, which is solid, moderate-to-strong stuff. This is an expert-only wave at that size. If you’re experienced and hungry, this is your session.
After that, it’s back to small fry. Monday the 21st through Saturday the 26th: wave heights under 3 ft, wind shifting between NE, E, N, W, WNW, and NW. A couple of glassy moments on the afternoon of the 22nd, but the swell is only 1 ft. Combined energy drops to 14, 49, even 2 at one point. Pretty much flat.
Water temp is 59°, which is average for this time of year.
So yeah, set your alarm for Sunday, September 20 morning. The rest? Not much to write home about.

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.
