The Lowdown
Alright, Rusty here again. Let’s talk Octagon House, but this time in feet and miles per hour.
Honestly, this is a rough one. For the first week and a half, we’re looking at tiny waves—0.3ft to 2ft—with mostly onshore or cross-onshore wind, so the surface is all chopped up and ugly. The combined wave energy is mostly weak, staying below 100 for days. There’s a lot of “poor surf conditions” in the forecast, so don’t get your hopes up.
Water temp is about 87°F, a little warmer than normal for the season, so it’s nice for a dip, but not for surfing.
The only real window to watch is Monday afternoon, September 14th. The swell bumps up to about 4ft from the SSE, with a period of 7 seconds, and the energy finally gets moderate (129). The wind turns light offshore from the NW, and the report says “clean.” That’s your one shot in this whole 16-day outlook. It’s not big and the period is short, so the waves will be a bit weak and crumbly, but it’ll be rideable and clean.
Octagon House is a fairly consistent, beginner-friendly spot, exposed to southeast swell, which is what we get. Just keep in mind that crowds are possible here sometimes, and with nothing else going on, others might have the same idea.
After that brief highlight, it’s back to small swell and onshore or cross-shore wind right through to the end. September 20th and 21st show a little more energy (up to 49), but the waves are only 1ft to 2ft and the wind is onshore—not worth it.
So, one day to pencil in: September 14th, Monday afternoon, clean 4ft SSE swell at Octagon House. The rest? Leave the board in the car. But forecasts can change, so don’t give up entirely.
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.
