The Lowdown
G’day, Rusty here. Let’s talk about what’s coming up for North Moana Beach.
Right now, the outlook is a tough one. There’s barely a wave to get excited about for the entire 16-day forecast. The first recommendation doesn’t even really land until the morning of Friday the 28th of August, and even then it’s a scrappy little thing. Before that, we’re looking at a solid 8-day stretch of flat, weak, or messy conditions. The swell is tiny, periods are short, and the wind is mostly cross or onshore, making it a real struggle to find anything rideable. The water temp is sitting at 57°, which is pretty average for the time of year, so no surprises there.
Come Friday the 28th of August, there’s a bit of a pulse. A 3ft swell from the north, but it’s short period at 4 seconds, paired with a fresh offshore breeze on the morning. The combined energy sits at 54 (weak), so it’s not going to be powerful. It’s clean, but it’s not a standout—just the best of a bad bunch. The break is a beginner spot, fairly exposed, and often crowded, so you’ll have company. The swell direction is N, which isn’t ideal for the optimum WSW, but it’s what we’ve got.
Saturday the 29th of August tries again with a 0.7ft, 13-second groundswell from the WSW, but the wind swings to a strong cross-on with rain showers, making it lumpy and messy. The energy is even weaker at 20. Not worth paddling out for.
The rest of the run into September is more of the same: tiny waves, cross-shore or onshore winds, and most days scoring a 0 out of 10. The morning of Wednesday the 2nd of September shows a 3ft swell from the WSW with a moderate cross-shore, energy up to 64 (still weak), but it’s the only half-decent pulse in the second week. The swell direction is a better match for the break, but the wind is not clean enough to make it shine.
Honestly, mate, this is a flat spell you’d want to sit out. The setup is too weak for paddle surfing, and if you’ve got a kite, you might get more out of the wind than the waves. Conditions can change, but right now, it’s a waiting game.
Rusty.
