Table - best surf conditions forecast for North Moana Beach over the next 16 days.
Alright, let’s get into it. The outlook for the next two weeks is a quiet one, I’m afraid. For the entire 16-day window, North Moana Beach is the only break in the picture, and it’s not looking like the kind of place we’d normally get excited about.
Right now, starting Sunday the 12th, we’ve got a bit of a lumpy mess. Some clouds overhead, a stiff onshore breeze out of the west at 22 mph, and a short-period 5ft swell from the west. The combined energy is moderate at 200, but the wind is just tearing it up, making for poor surf conditions. That’s the theme for the first few days.
Monday the 13th isn’t much better. The swell drops to 4ft and the wind is still onshore, though easing a bit to 16 mph. Still poor. Tuesday the 14th sees the swell shrink further to 3ft, and the wind swings to a light cross-onshore, but the surf is tiny and weak. By Wednesday the 15th, we’re down to 1ft. The water is about 58°F, which is just a touch cooler than usual for this time of year, but nothing wild.
The whole period is a long stretch of tiny, weak waves and mostly onshore or cross-off winds. The combined energy readings are mostly two-digit weak values, with a few low three-digit ones like 128 on the 20th, but even then the surf quality is labelled poor. The swell is short-period, often 5 or 6 seconds, so it’s just not holding any real shape.
Friday the 24th offers a bit of a glimmer. The wind goes cross-off from the southeast, and there’s a little 2ft swell from the northwest, but the period is a short 4 seconds. The combined energy is only 16. It’s clean, but it’s barely surfable.
There’s really nothing here that stands out. No standout session, no day to circle on the calendar. This is one of those stretches where the ocean just goes quiet. It’s a blank run for the area, and it happens. The best advice is to leave the boards in the car and maybe check the forecast again in a few days.

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.

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.
