The Lowdown
G’day, Rusty here. I’ve had a good look at what’s on the cards for Octagon House over the next couple of weeks, and I’ll be straight with you—it’s a tough stretch. We’re looking at a long, dry spell with barely a wave worth paddling for. The swell is small and weak, the wind is almost always messing things up, and the few moments that look half-decent are still nothing to get excited about.
The water is sitting at 87°, which is a touch warmer than normal for this time of year, so at least the wait won’t be a cold one.
Friday, July 24th through to Monday, August 4th is pretty much a write-off. The swell is tiny—hovering around 1 ft to 3 ft—and coming from the south or southeast with a short, weak period of 4 to 6 seconds. The combined swell energy is low, often under 100 (96 or less), so there’s just no grunt in the water. On top of that, the wind is almost always cross-on or cross-shore, blowing at 6 mph to 19 mph, leaving the surface choppy and lumpy. It’s a real struggle.
There is one tiny window that’s more promising but still not a standout. On Sunday, August 2nd in the morning, we get a bit of a shift. The wind goes cross-off from the WSW at 12 mph, which would clean things right up. The swell bumps up to 3 ft from the south at 6 seconds, with the combined energy hitting 56. It’s still small, but that clean face could make for a few fun, crumbly waves if you’re on a longboard. The crowds here are listed as “sometimes,” so you might have a bit of company, but it shouldn’t be a zoo. It’s the best we’ve got, but keep your expectations in check—it’s not a day to call in sick for.
From Monday, August 3rd onward, it’s back to the same story: small swell, shifty winds, and poor conditions. The swell stays under 3 ft until the end of the forecast, with periods rarely getting over 6 seconds. The combined energy stays weak, mostly between 29 and 61. It’s a long, quiet period.
So, to sum it up: no real gems in the 16-day window. The only flicker of hope is that Sunday, the 2nd, might offer a clean but small session. For the rest, it’s a good time to check your gear, watch the forecasts, and wait for a better run. The ocean will turn around—it always does.
Rusty.
