The Lowdown

Alright folks, let’s cut to the chase. The next two weeks are looking like a total flat spell. We’ve got a big gap at the start with absolutely nothing worth getting wet for.

For days on end, we're looking at weak, tiny surf. Swell heights are mostly under 0.7m, coming from the south and southeast with a short, weak period of 4-5 seconds. The wave energy is pathetic, mostly in the single digits and low teens (like 7, 8, 9, 13, 16). The wind is mostly cross-on or straight onshore, which is just going to make everything messy. There's also a few mornings with a chance of thunderstorms. It's a complete shutout.

This pattern is just going to stick around through the first week of September. The swell stays small and weak, the energy rarely gets past 20, and the wind stays onshore. This is one of those times where the ocean just goes to sleep. It happens, but it won't last forever, so keep checking the charts.

If you're really jonesing for a paddle, there is one small window of hope at the very end. On the 11th of September, we see a slight bump. The swell gets to 0.9m from the SSE with a period of 5 seconds. The energy is still weak (41), but the wind finally turns cross-off from the NNE in the morning, which would give us some clean conditions. That's the only option in the whole 16-day window. It's still small, but it's something.

Octagon House is the only break that's going to see anything. It’s a fairly consistent spot, so this small pulse might show. The swell direction is from the SSE, which is a bit south of its optimum SE direction, but beggars can't be choosers. Crowds are possible, as this might be the only place with a wave. For a beginner, it'll be fine, but anyone looking for real waves will be disappointed. There's nothing big enough here to worry about, so no expert-only territory.

That's about it. Nothing to get too excited about, just a small, clean window at the very end of the forecast.

Rusty out.

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.
