Alright, Rusty here. Let's talk about what we're looking at for Octagon House.
This is a tough stretch, I won't lie to you. We're looking at a two-week-plus run where the surf just never really gets its act together. The swell energy is weak across the board, and the winds are mostly working against us, especially for a spot that's exposed to the southeast.
Water temp is sitting at a balmy 86°F, a touch warmer than usual for this time of year, so at least you won't be cold while you're staring at flat lines.
For the first week, from Thursday the 9th of July all the way through to Wednesday the 15th of July, it's grim. Swell heights are struggling below 3ft, with periods of 4 to 7 seconds – that's short-period, weak wind swell with no punch. The combined energy is in the double digits for most sessions, only getting up to a weak 59 on the Saturday morning. And the wind? Mostly cross-onshore, chopping it up. We see a couple of "on" wind afternoons, but with nothing behind the swell, it's a waste. There is no standout session here; it's all poor surf conditions.
Moving into the second week, from Thursday the 16th of July, things don't improve much. We get a tiny bump on Friday the 17th afternoon, with a height of 4ft from the SSE and swell energy hitting 128 (moderate). But that's it – just a bump. The period is still only 7 seconds, so it's small, weak, and short-period. The rest of that week and into the week after sees nothing but knee-high slop. By the time we get to the 23rd and 24th of July, we're back to 1ft and 2ft waves with energy in the teens.
Honestly, there's no best day here. Nothing is even close to a standout. For a spot that's "fairly consistent," this is a proper flat spell. If you're really desperate, the afternoon of Friday the 17th of July might give you a few close-out crumbly 4ft waves, but with onshore winds, it won't be pretty. Save your energy. This area is just in a deep funk.
Rusty.

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.
