The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer around Octagon House over the next couple of weeks.
Honestly, I’m looking at a pretty bleak run. Straight up, there’s no good surf on the cards for the entire 16-day window. We’ve got a long stretch of small, weak, and mostly onshore wind-affected waves. The first few days are a washout, and it doesn’t really get any better. The combined swell energy is pitifully low, barely cracking 30 or 40 (32 to 47) in the early days, and then it just fades out. Water temperature is about average for the time of year, nothing unusual there.
The first real flicker of anything that might be considered surfable is a brief moment on Sunday morning, the 16th of August. We’ve got a tiny 2ft swell from the SSE, but the period is a short 6 seconds, so it’s weak. The wind is glassy, though, which is a major positive for the surface. The combined energy is a measly 21, so it’s not going to have any push. For a beginner, it might be a paddle, but it’s not really a wave.
After that, it’s a desert. The next few days are even smaller, with onshore and cross-onshore winds from the south and southwest, keeping everything messy. The swell drops to 0.7ft and 1ft, with periods up to 10 seconds, but the wind is just bad.
We finally get a bit of a break in the pattern on the 27th of August, Thursday morning. The swell picks up to 3ft from the SE, with a 5-second period. The wind is glassy again, so the surface will be clean. The combined energy is still only 32, so it’s not powerful. Then on the 28th of August, Friday morning, we have a light cross-offshore wind from the WSW, which is a good direction for this spot, with a 2ft SE swell (6-second period). The combined energy is 20. It’s clean, but small.
Overall, this is a proper flat spell. For an area where consistent surf isn’t the norm, this kind of blank run is par for the course. It’s a waiting game. The forecasts can change, but right now, there’s nothing to get excited about. If you’re desperate, the glassy mornings on the 16th or the 27th might give you a solo session on a longboard, but don’t expect much.
Rusty.
