Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.

First up, we’re looking at a pretty flat spell. That water temp is sitting at 86°F right now, a touch warmer than normal for the time of year, so it’s nice for a paddle, but the surf? Honestly, there’s hardly a ripple for the first week and a half. The first ten days or so are a write-off – tiny, weak swells, choppy cross-shore winds, and conditions consistently poor. There’s no rideable surf to speak of from the 7th through to the 17th, so you can leave the board at home.

The first real glimmer shows up on the morning of Saturday the 18th. Octagon House picks up a 3ft swell from the SE, period 10 seconds – that’s a bit more push behind it, combined energy of 135 (moderate), and the wind is light and cross-offshore. Conditions will be clean. The afternoon goes south with stronger cross-onshore wind and choppy water, but that morning window is your best shot for a long while. It’s a beginner-friendly break, fairly consistent, but the crowds will show up sometimes, so expect company.

After that, it’s back to mediocrity. Sunday morning the 19th has a clean window with light cross-offshore wind and a 3ft SE swell, but the period drops to 8 seconds and energy is only 100 – it’s surfable but nothing special. Then we silence again until the 21st and 22nd, when the swell finally bumps up to about 5ft from the SSE, period 7 to 8 seconds, energy hitting 249-247 (moderate to strong). But the winds are messy – cross-shore and cross-onshore – making it choppy and lumpy. That size is fine for stronger paddlers, but beginners might find it a handful, especially with the short-period chop.

Honestly, the standout here is the morning of Saturday the 18th at Octagon House. It’s not a world-beater, but it’s clean, there’s some energy, and it’s the only real window of quality in a long, flat run. The rest of the period is forgettable.

Rusty, signing off.

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.
