The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Octagon House over the next couple of weeks.
Right off the bat, I gotta be straight with you – there's nothing on the cards here. We are looking at a solid 16-day stretch with absolutely no surf worth paddling out for. Every single session is rated as poor surf conditions, and it doesn't let up. From Wednesday morning the 22nd of July all the way through to Thursday afternoon the 6th of August, you're not going to find a wave worth your time. That's a long, blank run.
The issue is a combination of factors. For the first week or so, the swell is tiny – mostly around 1ft to 3ft – and it's coming from SSW or SSE. The period is short too, mostly 4 to 6 seconds, so there's no grunt behind it. The combined wave energy is weak, staying well under 100 for the entire 16-day window. We see it nudge up to just 109 on Thursday afternoon the 23rd, but that's still in the weak range and it comes with a poor wind. In fact, the wind is pretty much always working against us – cross-on, cross-shore, or just plain onshore. There's one morning, Thursday the 23rd, where the wind is cross-off from the NNE at 9 mph and the wave comment says "clean", but the swell is only 2ft with a 5-second period from the SSW. It's just not enough to build any kind of rideable wave. Later on, around the 1st and 2nd of August, the swell bumps up to about 3ft, but the period stays short and the wind is either cross or cross-on from the S or SW, so it'll be choppy and messy.
For the beginner crew, the swell never gets above 5ft, so size isn't the problem – it's the complete lack of any organised swell and the poor conditions. Honestly, with the setup here at Octagon House being an exposed beach break, and with these persistent cross-onshore winds and small, weak swell, this looks more interesting for a kite surfer than someone with a paddle board.
The water temperature is sitting at 86°, with an anomaly of 2°, so that's pretty much average for the time of year. But you'll be sitting on a flat ocean waiting for something that isn't coming. It's a tough outlook, but this is just one of those stretches. Forecasts can change, but right now, there's nothing to recommend.
Rusty.

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.
