The Lowdown

Gather 'round, crew. Rusty here. I've been staring at the charts for Octagon House, and well, it's a tough one. The whole 16-day window looks like a total flat spell. There's nothing to get excited about, not a single session worth paddling out for. The water's sitting at a warm 86.2°F, which is about a degree and a half warmer than usual for this time of year, so you'd be having a nice swim, but that's about it.

The combined swell energy is tiny, barely making it past 24 (24) on the best of the bad days, and it drops off to almost nothing after that. We're looking at tiny, weak swell from the SSE and S, mostly under 2.0ft, with periods so short, between 4 and 6 seconds, it's just wind chop. The wind is mostly onshore or cross-onshore from the S and SSE, keeping things messy. There's a brief moment on Monday morning, the 17th of August, with glassy conditions and a tiny 1.6ft SE swell, but it's just too small to do anything with. On Tuesday the 18th and Friday the 28th of August, we get a clean cross-offshore breeze, but the swell is practically non-existent at 0.7ft and 1.0ft. It's a long, dry stretch. Honestly, with the consistent onshore flow and tiny waves, this setup looks more interesting for a kite surfer than a paddle surfer.

So, save your energy and your wax. There's nothing on offer here for the next two weeks. Forecasts can change, but right now, it's a total blank.

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.
