The Lowdown

Alright folks, Rusty here. Let's be straight with you – the outlook for the next couple of weeks is a tough one. We're looking at a real dry spell, a proper flat spell for Octagon House. There's a run of days with nothing worth paddling out for, and honestly, it's a bit of a bummer. The forecast shows a big gap with no real surf on offer from the start right through to the end of the period.

The first real chance of anything comes on the morning of the 26th of August. We get a little bump of swell, about 2ft from the SSE, and the wind goes glassy. It's a moment of complete calm on the water, and that's always a beautiful thing. But the period is a short 4 seconds, wave energy is a weak 18, and it's still classed as poor surf. You'd be out there on a longboard, maybe, just enjoying the stillness. It's barely a ripple.

The only other morning that looks clean is the 27th of August. Again, glassy winds, this time from the SW, and a tiny bit of swell at 2ft from the SSE. The period is still short, 4 seconds, and the energy is knocked down to 12. It's another one for the absolute beginner, or for a very patient soul on a foamie looking for a gentle push. The water temperature is sitting at 86°, which is a touch warmer than normal for this time of year, so at least you won't be cold while you're sitting there in the glassy calm.

Other than those two mornings, from the 15th of August all the way through to the 30th, it's a write-off. The wind is mostly onshore or cross-onshore, the swell is tiny, and the conditions are consistently described as poor. There's just not enough energy in the water. The best way to look at this is that it's a blank run for the area, and it won't stay this way forever. Forecasts can change, so don't lose hope, but for now, leave the boards in the shed.

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.
