The Lowdown
Alright folks, Rusty here. Let’s be straight with you. I’ve looked at what’s coming our way for the next couple of weeks, and honestly, it’s a tough one. We’re looking at a long, flat stretch.
The whole 16-day window is a write-off for any decent surf. From the 4th of September right through to the 19th of September, the only break we’ve got any data for is Octagon House. It’s a beginner-friendly spot, exposed to the swell, but it just isn’t going to do a thing. The combined swell energy barely gets into double figures, peaking at a measly 35 (moderate energy) on the 17th of September afternoon, but even then the swell is a tiny 2ft from the SSE with a short, weak period of 4 seconds. That’s not surf, that’s a ripple.
The first few days are flat. Friday the 4th has a pathetic 2ft south swell and a cross-onshore wind. Saturday the 5th morning is glassy but the swell is only 1ft. We get a few glassy mornings on the 7th, 8th, and 10th, but the swell never gets above 1ft. It’s just not enough to push a wave.
The closest thing to a pulse comes on the 17th and 18th of September. The combined energy climbs to 35 and then 32, but the swell is still only 2ft and 3ft from the SSE with a period of 4 to 5 seconds. Plus, the wind is a moderate to fresh cross-shore, making it lumpy and messy. Even for a beginner spot, this is unrideable. The water temperature is 87°, which is a touch warmer than normal for this time of year, but that’s the only highlight.
This is one of those blank runs. When a spot is this consistently flat, it’s just the area’s nature. Don’t hold your breath. Forecasts can change, but right now, the best advice is to find another hobby for a few weeks.
Stay tuned, and I’ll let you know if anything changes.
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.

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.
