Alright, Rusty here again. Let’s break this down the other way.
Honestly, straight off the bat, it’s looking pretty flat and quiet. There’s no real surf to speak of for the first little while. We’ve got a long dry spell at the start here, with nothing really worth getting wet for from Tuesday the 7th all the way through to Sunday the 12th. It’s mostly tiny little bumps – 0.3ft to 3ft of swell coming from the south and southeast, but the period is super short at 4 to 6 seconds, and almost every session has some kind of cross or onshore breeze chopping it up. The combined swell energy is just weak, sitting between 7 and 58 (weak), so there’s just no power in the water. For a beginner-friendly spot like Octagon House, it’s just not doing anything.
Now, if we jump ahead a bit, Monday morning the 13th of July starts to look a little more interesting. We’ve got 3ft of swell from the SSE with a 6-second period, but the real kicker is the wind. It’s a light cross-offshore breeze from the WSW at 6 mph, which is clean. The swell energy creeps up to 62 (still weak), but it’s the first time the conditions actually line up for a surf. The wave comment says “surfable waves but very ordinary conditions” with a score of 1, so don’t get too excited. It’s tiny and weak, but at least it’s clean. That’s about the only highlight on the whole forecast.
After that, we go straight back into the same story. From Monday afternoon the 13th all the way through to Wednesday the 22nd of July, it’s the same old run of small, weak S and SSE swells, with periods never getting above 7 seconds. The wind is mostly cross-on or onshore, often moderate to fresh, and the energy readings sit between 13 and 57 (weak). There’s nothing that breaks the pattern. It’s just a long stretch of poor surf conditions.
So, the bottom line here is that Octagon House is looking at a long, flat, and mostly blown-out run. The only flicker of something worth checking is that Monday morning, the 13th of July, with the clean wind, but it’s not going to get the heart racing. Sometimes it’s like this around here – you just have to wait for the next change. Forecasts can always shift, but right now, it’s a waiting game.
Rusty.

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.
