The Lowdown
Alright, I’ve had a good look at the charts for the Octagon House area over the next couple of weeks, and I’ll be straight with you—it’s a tough stretch. The forecast is almost completely flat, with only tiny dribbles of swell showing up, and the wind is rarely doing us any favours. We’re looking at a solid gap of poor surf conditions right through the end of August and into early September.
The water temperature is sitting at about 87°, which is a touch warmer than normal for this time of year. Makes for a nice warm paddle, but you’ll be floating around waiting for a wave that never really comes.
The first real sign of life doesn’t show up until Wednesday morning, September 9th, when a small southerly swell nudges up to 4 ft. The wind is a light cross-offshore from the WSW at 6 mph, which will keep the surface clean. The combined swell energy is still pretty weak though, only around 85. That’s about as good as it gets in this whole outlook, and it’s still not great. The swell direction is from the south, which is a bit off the optimum SE direction for Octagon House, so it won’t be wrapping in perfectly. The period is short at 5 seconds, so it’ll be a bit weak and crumbly. This is a beginner-friendly size, but don’t expect much more than small, soft waves.
Thursday the 10th looks similar, with southerly swell around 3 to 4 ft, but the wind swings more onshore and picks up, making it choppy and messy. The energy bumps up to 124 by the afternoon, but it’s all onshore junk.
Honestly, there’s no standout session in this entire 16-day window. The best you can hope for is that Wednesday morning on the 9th, with clean-ish conditions and tiny waves. But if you’ve got a kiteboard, the afternoon on the 9th has a fresh cross-onshore wind at 19 mph and 4 ft swell—that setup is more interesting for kite surfing than paddle surfing.
Keep an eye on the forecasts, because things can change, but right now it’s a waiting game. Hang in there.
