The Lowdown

Alright, Rusty here. Let's take a look at what's on the menu for Octagon House over the next couple of weeks.

Well, I gotta be straight with you – it’s looking pretty bleak for the next little while. We’ve got a real flat spell on our hands. The first surfable day I can see is for Monday morning, August 31st, but honestly, we’re talking about a tiny 0.3 ft SE windswell with a period of just 9 seconds. The combined energy is a measly 4, so it's barely a ripple. The water's a touch warmer than normal at 87°. Conditions are clean with a light cross-offshore breeze, but there's just no power to work with. The rest of that day and all through the first week of September into the second, we’re looking at tiny, weak waves and mostly onshore or cross-onshore winds. You'll be seeing a lot of "poor surf conditions" notes in the log.

We finally see the energy tick up a little around Thursday, September 10th, with the swell pushing to 3 ft from the SSE, but the period is a short 5 seconds and the wind is a moderate cross-onshore, making for choppy conditions. The combined energy hits 41, which is still weak. That pattern of cross-onshore wind and small, weak swell pretty much continues straight through to the end of the forecast on Tuesday, September 15th.

There isn't a single standout session in this entire 16-day window. We're looking at a two-week gap with no real recommendations. The only slight glimmer is Monday morning, September 7th, where we get a brief window of glassy conditions with the wind going WNW at 3 mph. But even then, the swell is still a pathetic 1 ft. Honestly, with this constant small, weak swell and onshore wind, you'd probably have more fun on a kite than a paddle board right now. It’s a tough run, but that’s the way it goes sometimes.

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.
