The Lowdown
G’day, Rusty here. Look, I’m gonna level with you – this 16-day stretch for Octagon House is a tough one. We’ve got a long, quiet run ahead. The good news is, the water temp is sitting right around 86°, which is pretty much spot-on for this time of year, so you won’t be freezing your toes off.
The first real sign of life doesn’t show up until Monday, July 27th. The swell starts to tick up a little, but it’s still a messy story. Wednesday morning, July 29th, is the only time we see a bit of moderate energy, with the combined swell energy hitting 113. That’s coming from the SSE at about 4ft, but the wind is a cross-onshore from the SSW at 15 mph, so it’s gonna be choppy and pretty poor. This is really only one for the die-hards who don’t mind a battle.
Honestly, there’s no standout session here. The whole period is dominated by tiny, weak swell and choppy onshore winds. It’s a beach-break setup, so with the wind and small slop, you’d honestly have a better time on a kite than a surfboard for most of it. If you’ve got to get wet, Wednesday morning, July 29th, with that 4ft SSE swell is your best bet, but keep your expectations on the floor. It’s a lean spell, mate.
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.
