The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this stretch is flat. There’s no sugar-coating it. The entire 16-day window from July 14th to July 29th is a total dud for Octagon House (exposed, SE). We’ve got a long, brutal gap with zero surf worth paddling out for.
The first recommendation doesn’t even show up. It’s just a long stretch of “poor surf conditions” from the get-go. Even the stronger winds later on don’t bring any real swell. The combined energy of all swells directed here barely crawls into the weak range, peaking at a paltry 120 (moderate) on the 29th, but it’s accompanied by chunky cross-onshore winds and a messy 4ft SE swell.
Water temp is sitting at 86°, which is a touch warmer than normal for this time of year, but that’s the only highlight. The swell is tiny, short period, and mostly from the SSE or SSW—nowhere near the optimum SE direction. It’s a beginner spot, but with waves that small and the wind howling onshore, it’s more of a lake than a break.
The only glimmer of something clean is a few glassy moments on the morning of the 21st and the 22nd, but with swell heights of 1ft, it’s not even a ripple. For the rest, it’s just cross-on chop and tiny windswell. If you’re a kite surfer, the stronger afternoons of the 27th and 28th with 12-16 mph cross-onshore winds and that 4ft choppy mess might look interesting, but for a paddle surfer? Forget it.
It’s a blank run, but for this area, that’s not unusual. Forecasts can change, but right now, leave the board at home.
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.
