The Lowdown

Alright, let’s break down what’s happening at Octagon House. I’m not gonna sugarcoat it – it’s a lean run.

Looking at the whole 16-day picture, we’ve got a lot of flatness to start. From now until about the 14th of September, the swell is tiny, rarely getting above 2 ft, and the wave energy is weak, with numbers mostly in the single digits or low double digits. The wind is often blowing onshore or cross-onshore from the south to southeast, making things choppy. You get a few glassy mornings, like Saturday and Sunday, but with waves only 0.3 ft to 0.6 ft, it’s barely enough for a paddle. It’s poor conditions across the board.

Things try to pick up a bit around the 14th and 15th of September. On Monday the 14th, the swell builds to about 4 ft from the SSE by the afternoon, and the combined energy finally hits a moderate range (around 93 to 107). The period is still short though, at 6 to 7 seconds, so the waves won’t have much push or shape. The wind stays onshore or cross-onshore from the east, so it’ll be a bit messy.

The best window, if you can call it that, is the morning of Tuesday the 15th of September. You’re looking at about 4 ft from the SSE with 107 of wave energy. The wind is a light easterly breeze, which keeps it ridable. For a beginner spot like Octagon House, this is the most likely time to get a few crumbly ones. It’s not a classic day by any stretch, but it’s the pick of a very quiet period.

After that, the swell fades back down under 3 ft through the rest of the second week, with the wind staying onshore. There’s one glassy morning on Sunday the 20th of September, but with only 2 ft of weak, short-period swell (17 energy), it’s another day for a log and low expectations.

Bottom line: there are no standout days here. If you’re really keen, aim for the morning of Tuesday the 15th of September. Otherwise, you’re better off waiting for the next system.

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.
