The Lowdown
Well, folks, it’s Rusty here, and I gotta be straight with you—this stretch is pretty grim. We’re looking at a long, drawn-out period of flat, weak surf with hardly anything to get excited about. The water temp is about average for this time of year, so at least you won’t be freezing while you stare at the ocean.
Let’s break it down. Starting now, Monday the 31st of August, through to the 11th of September, it’s a whole lot of nothing. Swell heights are tiny, barely 0.3 ft to 1 ft, with periods under 5 seconds—basically wind chop. The wind is all over the place, mostly cross-shore or onshore, and the wave energy is pitiful, with readings like 4 to 16 (weak energy). You’d be better off taking up kite surfing if you’re desperate for a fix, because the surf is just not happening.
There’s a glimmer on Saturday the 12th of September morning. Octagon House (Octagon) sees a glassy morning with a small 5 ft swell from the SSE, period 6 seconds, and the combined energy climbs to 181 (moderate). The wind is light, glassy, so it’s clean—but it’s still pretty ordinary. This is the best we’ve got, and it’s barely a 1 out of 10 for surfable waves. It’s a beginner-friendly size, but with that short period, don’t expect much push.
Then Sunday the 13th of September morning offers another glassy moment, with 5 ft from the SE, period 6 seconds, and energy at 127 (moderate). Again, it’s clean but hardly a standout. The rest of the 16 days? More poor conditions, with onshore winds and tiny waves. The last day, Tuesday the 15th of September morning, brings a clean, offshore wind from the NW, but the swell is only 1 ft from the SSE—just a ripple.
Honestly, there’s no real standout here. The best bet is early Saturday the 12th, but even then, it’s a weak offering. Crowds are possible at Octagon House, but who’s gonna bother? This is a blank run, and for this area, it’s not that unusual. Forecasts can change, but for now, I’d save your energy.
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. If you surf the same spot (Octagon House) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
