The Lowdown
Gutted, folks. I’ve run the numbers for the Octagon region, and it’s a grim stretch ahead. The whole 16-day window is a total write-off for paddling. We’re looking at a solid two weeks-plus of nothing but small, weak, and messy surf. There’s no getting around it: the swell just isn’t there. From Wednesday the 19th right through to Thursday the 3rd of September, every single forecast window comes up empty. We’re talking about a real drought.
The only break on the radar, Octagon House (Octagon), is a beginner-friendly, fairly consistent spot that needs a southeast swell. But it’s simply not getting anything. The water is a very warm 87°, which is a touch warmer than normal for this time of year, but that’s about the only highlight.
To give you an idea of how poor it is, the combined wave energy only ever gets into double digits – values like 17, 35, or 46 – which is weak energy, and the surf height never even gets close to 3 feet. The period is mostly short, around 4 to 5 seconds, which is just wind-slop, not real swell. There is a brief pulse of longer-period energy around the 30th and 31st of August, but it’s puny at 0.3 ft, so it doesn’t matter.
The winds don’t help either. Most days are a cross or cross-on shore, with 12 to 18 mph breezes chopping up what little texture there is. There are a few mornings, like Saturday the 22nd, Sunday the 23rd, and Thursday the 27th, that are clean with light cross-off winds, but with only 2 ft to 3 ft of weak, short-period swell, it’s still a guaranteed flat, frustrating session. Thursday the 3rd of September is glassy, but the swell is a pathetic 2 ft of short-period chop. Not worth getting wet.
If this was a beach or reef setup with a bit more push, you could argue it might be interesting for a kite surfer, but it’s not. Honest truth? It’s a blank run. It happens in this area, and it tends to hang around. We just have to sit tight and wait for the ocean to switch back on. Forecasts can change, but this window looks dead.
