The Lowdown
Hey folks, Rusty here. Lookin’ at the next couple of weeks for Octagon House, and honestly, it’s a real bummer. There’s barely a ripple of surf worth paddlin’ out for. The swell is tiny, hangin’ around 1ft to 3ft, with weak energy – the combined energy numbers never even hit 100 (mostly in the teens to sixties). The wind is mostly cross-on or cross, and the swell direction is comin’ from the south, not the southeast that this spot really likes. Water temp is a warm 85°F, which is pretty normal for the season.
Let’s run through it. Sunday July 19 afternoon – some clouds, 1ft from SSW, cross-on wind, poor. Monday morning the 20th – clear, 2ft from SW, cross-off wind, clean but tiny. Still poor. The whole week stays like that – tiny swell, unfavourable wind, weak energy. The only tiny glimmer is on Saturday August 1st in the morning. That morning we’ve got 3ft from SSW, a cross-off breeze, clean conditions – the best of a bad lot, but still very ordinary. The combined energy is just 52, and the swell period is short (5 seconds). So it’s surfable, but only just. After that, it’s back to poor conditions right through to Monday August 3rd.
For a beginner, the small size might be okay, but the wind isn’t clean enough most of the time. For anyone else, there’s just no push. This kind of blank run happens here sometimes – it’s fairly consistent overall, but when it’s flat, it’s flat. Stay tuned, forecasts can change, but right now it’s a long stretch of nothin’.

A general guide to surfing at Octagon House can be found by selecting the local surf guide option on the grey menu.

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.
