The Lowdown
Alright mate, Rusty here. Let’s be straight with you – this next stretch is a quiet one for the Octagon House area. Over the whole 16-day run, from Wednesday the 19th of August right through to Thursday the 3rd of September, there’s not a single standout session. Every single check-in comes back with “poor surf conditions,” and the score is a flat zero the whole way through. The combined swell energy is weak, barely cracking double digits – mostly between 4 and 24 (weak energy). You’re looking at tiny, short-period windswell, mostly from the S or SE, with heights hovering around 1 ft to 2 ft, and periods of just 4 to 8 seconds. That’s mushy, gutless stuff.
The wind is no help either. Most mornings are cross or cross-off, but afternoons turn cross-onshore or onshore, leaving chop in the lineup. A few mornings – like Sunday the 23rd, Tuesday the 25th, and Wednesday the 26th – do have clean conditions with light offshore or cross-off breezes, but the swell is still too small and weak to do anything with. The water temperature anomaly is about average for the time of year, nothing wild.
Bottom line: there’s nothing here worth paddling out for. The whole 16-day window is a blank run. For an area like this, that can happen – it’s not unusual to have a quiet spell, and forecasts can always change, but as it stands, leave the board in the garage.
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.
