The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at what’s coming for North Moana Beach over the next couple of weeks. I gotta be straight with you – this one’s a tough read. The whole 16-day stretch is a real struggle, with nothing but poor surf conditions across the board. From Monday the 17th of August right through to Tuesday the 1st of September, every single session is rated as poor. There are no standouts, no hidden gems, just a long, flat, or messy stretch.

The pattern is a mix of tiny leftovers and onshore slop. We start off Monday afternoon with a tiny 0.3ft swell from the SW, but with a 13-second period behind it, you’d think there’d be some hope. The energy is weak (7) and the wind is a moderate offshore breeze from the E, which would normally clean it up, but there’s just not enough water moving to bother. That sets the tone for the whole first week. The 18th and 19th see a bit of a bump, with a peak of 4ft on Wednesday morning the 19th from the WNW, but that’s a short-period chop at 5 seconds and a fresh cross-onshore wind from the NW at 19 mph. The energy climbs to 59, but it’s messy, lumpy, and not worth paddling out for.

The water temperature is sitting at 58°F, which is basically bang on average for the time of year (anomaly of -0.2°F), so no excuses there – it’s just the swell that’s missing.

The only real change in the pattern comes late in the second week. Thursday the 27th of August has a sudden spike of 8ft from the WSW, pushing the combined energy up to 637. That’s a strong pulse of energy, but it’s coming in with a short period of 7 seconds and a stiff onshore wind from the W at 16 mph. The surf quality is still rated poor. For a beach break like North Moana, that much swell with short period and onshore wind is going to be a washing machine – more of a messy, blown-out lump than a proper wave. This is the kind of setup that looks more interesting for kite surfing than paddle surfing. It’s far too big for beginners, and even for experts, the conditions are just not favourable.

After that, it drops right back down to tiny 0.3ft to 1ft stuff for the rest of the month, with a mix of glassy moments on Sunday morning the 30th and Monday afternoon the 31st, but the swell is just too small to do anything with. The 30th has a glassy 0.7ft from the WSW with 9 seconds, but the energy is just 8 – it’s a flat calm, not a surfable day.

Honestly, this is a blank run for North Moana. There’s nothing to get excited about. The whole 16-day forecast is a write-off. Forecasts can change, but right now, I’d leave the boards at home and go find something else to do.

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.
