The Lowdown
Alright folks, Rusty here. Let's be straight with you about what's on the table for Octagon House. We've got a full 16-day window, but I'll be damned if there's a single session in there that's worth wetting a board for. Every single entry in this period is flagged as "poor surf conditions."
We're looking at a long, flat run. From September 7th right through to the 22nd, the swell barely flickers. The biggest combined energy we see is a measly 38 (moderate energy) on September 20th, but even that's attached to a weak 3ft SE windswell with a short, crumbly period of 5 seconds. That's not surf, that's a washing machine. The vast majority of the time we're looking at combined energy below 20, which is basically a lake.
The winds are a mixed bag of cross-shore and onshore junk, with the odd glassy patch on a couple of mornings (like the 9th and 15th) but with absolutely no swell to ride. You could have it flat as a tack with a mirror finish, and it's still useless.
With swell heights barely cracking 2ft for most of the run and a beach setup, this is a kite surfer's paradise long before a paddle surfer's. There are no standouts here. Not one. The water temp is about 87°, which is a touch warmer than normal for this time of year, but you won't be in it long enough to notice.
This kind of blank run is just how it goes here sometimes. Don't bother paddling out. Give it a week and check the charts again.
Rusty.

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.
