The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for North Moana Beach over the next couple of weeks.
Straight up, I’ve got to be honest with you – this is a grim stretch. The whole 16-day window is essentially a write-off for any decent surf. We’ve got a long, dry gap from now until the end of the second week. The only real pulse of energy comes right at the very end, and even that one is a bit of a mess.
The forecast starts with nothing rideable. Friday afternoon the 4th sees a tiny 1ft swell from the WSW with a 9-second period, but it’s blown out by a 16 mph crosswind. The water is sitting at 58°F, which is about average for this time of year, but you wouldn’t want to be in it for the lack of waves.
Saturday the 5th is the biggest push of the whole period, but it’s a total no-go. The morning bumps up to 8ft from the West, but that’s coupled with a brutal 28 mph onshore wind and a short, weak 7-second period. The combined energy is moderate at 546, but with that wind, it’s just a washing machine. That afternoon is even bigger at 8ft (611 energy), but with the same onshore wind, it’s a full-blown mess. That’s expert-only, and even then, it’s not worth it.
We then slide into a full week of flatness. From Sunday the 6th right through to Tuesday the 15th, we’re looking at ankle-snappers at best, with most days reading 0.3ft or 0.7ft. The wind is often clean or glassy, like on the 8th, but there’s no swell to work with. It’s gonna be a long week of staring at flat water.
Finally, on Wednesday the 16th, we get a slight nudge. The morning shows 3ft from the West with a 5-second period, but the combined energy is only 64 – weak. The wind is clean from the ESE at 12 mph, so it’s pretty, but that short period won’t give you much push. The 18th of September (Friday) is the only day that stands out as a potential, but it’s a weird one. The afternoon shows a sudden jump to 10ft from the WSW with an 8-second period, and a massive 1318 energy. That’s a lot of water, but the period is short and the wind is a light cross-onshore. It’s only rated as marginal, possibly tide-dependent. That’s a heavy, lumpy closeout for a beach break like this – honestly, that setup looks more interesting for kite surfing than paddle surfing. It’s too big and short-period for a good time.
On the 19th, the swell drops back to 3ft with glassy conditions in the afternoon, but again, that 5-second period is just a bump.
The bottom line: there is nothing to recommend here. The only real energy arrives on the 18th, but with the short period and onshore wind, it’s a miss. For a spot that’s fairly consistent, this is a dud run. Forecasts can change, but as it stands, leave the board at home.
Rusty.

Information about the North Moana Beach Surf forecast
The above surf forecast table for North Moana Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at North Moana Beach can be found by selecting the local surf guide option on the grey menu. Our North Moana Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (North Moana Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
