The Lowdown
Hey folks, Rusty here. Let’s talk North Moana Beach.
Honestly, this forecast is a tough one. There’s basically no surf for the first week and a half – from now right through to Saturday the 24th of August it’s flat as a tack. Just tiny bumps and poor conditions, nothing worth paddling out for. Water temp is 57°, right on average for the season.
Finally, on Monday the 24th of August, we see a pulse. That afternoon a 7ft swell comes in from the WSW with a short 7-second period, and the combined energy hits 420 (strong). But that size is well into expert territory, and with short-period wind swell, it’s gonna be messy. Winds are light cross-onshore, so don’t expect any clean faces.
The real standout is Tuesday the 25th of August. Another 7ft swell from the SW, same 7-second period, and the energy tops out at 424 – the biggest we see. The wind is onshore by the afternoon, so early morning with a bit of cross-off (WNW at 9 mph) might be your best shot. It’s big, raw, and only for the experienced crew.
After that, it drops off fast. Wednesday brings tiny 2ft leftovers, and by the end of the month it’s flat again. So your only window is that Monday-Tuesday bump – and it’ll be a short-period, onshore mess. Not a classic, but it’s something.
Rusty.
