Table - best surf conditions forecast for Octagon House over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – this next 16-day window for the Octagon House area is a tough one. We’re looking at a long stretch of small, weak, and messy surf. The good news is, there’s barely any swell to speak of, so at least you won’t be tortured by what you’re missing. The bad news is, there’s barely any swell to speak of.
The first real chance to get wet doesn’t roll around until Thursday, July 16th. The swell is a tiny 3 ft from the SSE, but the period is a short 6 seconds, so it’s weak and gutless. The energy readings are in the low 50s and 60s – just a whisper of energy (59). The wind is a problem almost every day, mostly cross-onshore, chopping it up. Even on the glassy mornings, like Sunday, July 19th, the swell is only 1 ft. It’s barely going to break.
The best looking day in the whole run is actually the morning of Friday, July 25th. The swell picks up to 2 ft from the SE, still a short 5 second period, but the energy reading (30) is a little better. The wind is cross-on, but it’s clean enough that you might find a waist-high plus ripple if you’re patient. It’s a beginner-friendly height, but it’s not going to be good. Don’t expect a gem.
The truth is, this is a pretty blank run. The water temp is about average for the time of year, which is fine, but it doesn’t make up for the lack of waves. Honestly, with the winds and the small, weak swell, the setup looks more interesting for kite surfing than paddle surfing through most of this. Keep an eye on the charts, but don’t hold your breath.
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.
