The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Octagon House – and mate, I gotta be straight with you: there’s nothing on the menu for the next 16 days. Not a single session worth paddling out for. The whole run from August 31 right through to September 15 is a flat, frustrating stretch. We’ve got swell heights barely scraping 2 ft at best, and most of the time we’re looking at 0.3 ft to 1 ft dribble. The wave energy is weak as, with combined energy values sitting between 4 and 38 – that’s bottom-of-the-barrel stuff. No standouts, no highlights, just a whole lot of nothing.
The water’s a touch warmer than normal at 87° – not a surprise for this time of year, but it’s not gonna help the waves any. The wind’s all over the shop too: some mornings we get a bit of offshore or cross-off breeze, like on Tuesday September 1 with a light NW at 6 mph, or Sunday September 7 with a W cross-off at 6 mph, but the swell is so tiny it’s irrelevant. Even the glassy calm on Sunday September 6 – with zero wind – can’t do a thing for those 1 ft, 5-second slop. The swell direction is mostly SE or SSE, coming from the wrong side for any real energy, and periods are short (4 to 7 seconds) so there’s no push behind it.
If you’re a beginner, you’re not missing out – the biggest swell we see is 2 ft on September 12 and 13, but that’s still tiny and the period’s only 5 seconds, so it’s gutless. The wind picks up on a few afternoons, like a 16 mph S cross-on on September 11, making it choppy and messy. Honestly, this setup looks more like a kite-surfing breeze than anything for a paddle board. With a few breaks rated fairly consistent in the area, it’s a quiet spell – but this kind of blank run happens, and forecasts can always shift. Not much to get excited about, folks.
