The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at Octagon House over the next couple of weeks.
Right off the bat, I’ve gotta be straight with you: the surf situation is pretty grim for a while. There’s nothing worth paddling out for across the entire 16-day window. The combined wave energy is weak, barely hitting double digits for most of the first week. We’re looking at tiny, wind-affected slop. The water temperature is sitting at 86°, which is about normal for this time of year, so that’s one thing that’s not a headache.
The first ten days or so are a write-off. Winds are mostly cross-onshore, and the swell is under 3 feet with short periods. It’s a lot of choppy, crumbly junk. Even the occasional clean session with light offshore winds doesn’t help because there’s just no swell to work with. You’d be floating out there.
Now, from around Wednesday, July 30th, things look a little more interesting. The combined energy rises into the moderate range (164 – 167) and the swell bumps up to 4 – 4 feet from the SE. Still, the wind is a moderate cross-onshore, so expect bumpy, lumpy conditions. The period is only 7-8 seconds, so it’s windswell, not the clean groundswell we’d want. This is not beginner territory – that 4 foot swell with onshore wind will be a messy, challenging paddle. Honestly, at this point, with the cross-onshore wind and that short-period swell, the setup looks more interesting for kite surfing than paddle surfing.
The very end of the forecast, around July 31st, settles back down to 3 feet and the energy drops. There’s no standout day here, no hidden gem. It’s a long, flat spell for Octagon House. It tends not to stay this poor for long around here, so keep an eye on the forecasts. But for now, leave the boards in the car.
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.

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.
