The Lowdown
G'day, Rusty here, your local surf reporter. I've had a good look at the charts for North Moana Beach, and to be honest, it's a pretty quiet run we've got ahead. The 16-day window is looking flat, with no real standouts or even ridable waves on offer. The forecast is showing a whole lot of nothing, so if you're dead set on getting wet, you might be better off with a kayak or a paddleboard for the foreseeable future.
The pattern for the next couple of weeks is one of low energy and poor conditions. The swell is tiny, the wind is a mess, and the water temp is sitting at 57°, which is pretty average for this time of year. The first few days are a total write-off. Wednesday morning, August 5th, you're looking at a tiny 0.7ft of cross-shore junk with a combined energy of just 4, so it's a no-go. That flat, rubbish spell slides right through the end of the first week and into the second. Thursday and Friday are more of the same – barely a ripple. The wind is all over the shop, mostly cross or onshore, and the swell is just not there.
We get a bit of a bump around the weekend of August 8th, with the swell height pushing up to 4ft from the North, but the wind is howling from the North at 18-25 mph. That's a fresh to strong breeze, making for lumpy, messy conditions. It's not one for the paddle surfer, and with that much wind and a beach break setup, it might be more interesting for the kite surfers than the rest of us.
The early part of the following week, from Monday August 10th through to Wednesday August 12th, sees the swell climb a bit more, with the combined energy hitting 228 on Tuesday morning. But the problem is the wind is strong and onshore from the WSW, thrashing the surface. The size gets up to 6ft, which is getting too big for beginners, but the quality is just horrible. It's all stormy, rain-showers and chop. Not a good look.
After that, the energy drops away again. By Thursday August 13th, we're back to tiny 2ft surf and cross-onshore wind. The very end of the outlook, from Monday August 17th through to Thursday August 20th, shows a few little pulses of 2ft to 3ft swell from the North, but with light winds and some glassy patches. The problem is the swell is too small and weak, with a pathetic period of 4 seconds, to do anything with. There's just not enough push.
To be clear, if you're looking for a wave to paddle out and catch, there isn't one in this 16-day window. The blanks are long and drawn out. It's a quiet period for the area, and forecasts can change, but for now, it's a solid pass.
Rusty.
