The Lowdown
Alright, Rusty here again. Let’s be real – the next couple of weeks are a total bummer. The swell is tiny, the wind is all wrong, and there’s no surf to speak of. The whole 16-day window is a flat spell with no good options.
The only spot we’ve got is Octagon House, a beginner-friendly break that’s fairly consistent and exposed to the southeast. But the swell is just pathetic. We’re looking at knee-high slop, around 1ft to 3ft, all short-period windswell from the SSE and SE. The period is a lousy 4 to 6 seconds, so no power, no shape. The combined energy is weak, between 17 and 60 (moderate at best), and the wind is mostly onshore or cross-onshore, making it choppy and messy. A few mornings, like Thursday the 20th, we get a little cross-offshore breeze and clean conditions, but the swell is still only 2ft of weak slop. Not enough to get wet for.
The water temperature is about average for the time of year, but with no surf, it doesn’t matter.
Honestly, this setup looks more interesting for a kite surfer than a paddle surfer, with the onshore winds and those small, choppy waves. For the rest of us, it’s a solid two-week dust-off. It’s a blank run, but for this area, that’s not unusual. Forecasts can change, but for now, I’d leave the board in the garage and wait for something better.
Rusty.

Information about the Octagon House Surf forecast
The above surf forecast table for Octagon House provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Octagon House can be found by selecting the local surf guide option on the grey menu. Our Octagon House surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
