The Lowdown
Alright, Rusty here with the same story in feet and knots.
Straight up, the outlook for Octagon House is a total washout for the next 16 days. This spot is exposed to the SE, and the swell is coming from the wrong angles – SSW and S. The water is sitting around 85.8°, which is pretty normal for this time of year.
The whole thing starts on Tuesday, 21 July, with a flat 1ft swell from the SSW, a weak 4-second period, and combined energy of just 9 – that’s barely a ripple. The wind is light and cross-shore, but the surf is awful.
From Wednesday the 22nd through Friday the 31st of July, it’s a long, dry spell. The swell barely gets above 2.5ft, with periods stuck at 5 to 6 seconds. The combined energy stays weak, mostly in the teens to low 50s. The winds are mostly cross or cross-on, keeping the surface choppy. There’s a clean moment on Thursday morning the 23rd with a cross-offshore breeze, but the swell is still only 3ft – not enough to get the heart pumping.
August rolls in, and nothing changes. Saturday the 1st has a clean offshore morning with 2.3ft swell, but it’s weak. The rest of the week is the same old story – small, weak, and messy. The biggest wave we see is a 3.3ft on Monday the 3rd, but it’s cross-onshore and choppy.
There’s not a single day worth paddling out for. The swell is too small, the period is too short, and the winds are rarely clean. This is a real blank run. For a break that’s usually fairly consistent, it’s a tough stretch. Maybe you could get a longboard slide on a clean morning, but that’s a long shot. Forecasts can change, but right now, it’s a waiting game.

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.
