The Lowdown
G’day, Rusty here. Let’s be straight up – the next 16 days at Octagon House are a total write-off for any sort of decent paddle. We’re looking at a long, flat, and mostly messy run with nothing that’s worth waxing up for.
From August 24th right through to September 8th, every single morning and afternoon session comes in with a score of zero. The swell is tiny – hardly ever nudging above 2ft, and most days it’s a pathetic 0.3ft to 2ft from the SE or S. Periods are short, mostly 4 to 7 seconds, so no energy at all. The combined swell energy barely gets into double digits, typically sitting between 6 and 44 (weak). Winds are nearly always cross or cross-onshore, with a few clean moments on the mornings of the 27th, 28th August, and September 8th when it turns cross-offshore from the W. But even then, there’s simply no swell to work with.
Water temp is sitting at 87°F, which is a touch warmer than normal for the time of year.
Honestly, for this exposed beginner break (Octagon House), it’s a total bust. If you’re a kite surfer, maybe the cleaner breezes on those few mornings might offer something, but for a paddle surfer? Nothing. These blank runs happen here sometimes, and the forecasts can change, but right now, there’s no surf on the horizon.
Stay tuned, but don’t hold your breath.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Octagon House may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
