The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin'.

Well, I gotta be straight with you – the next 16 days are lookin' pretty grim. We’ve got a long stretch of flat, weak surf ahead. The first recommendation pops up on Sunday the 6th of September, but honestly, it's a dud.

Overall Pattern: The whole period is dominated by tiny, short-period wind swell. The energy is just not there. The combined swell energy is mostly weak, sitting in the single digits or low teens (values like 1, 2, 4, 7, 13 – all puny). There’s a small peak around 13th-14th September but even that only reaches 29. It’s gonna be a tough 16 days.

The Breakdown:

Starting off, Octagon House is your only option, and it's a beginner-friendly spot. But don't get your hopes up. The first few days, from the 6th through the 8th, we’re talking ankle-snappers at best – 0.3ft to 0.7ft swell from the east and southeast. The wind is mostly onshore or cross, making it a mess. We’ve got a risk of thunderstorms in the mix too.

Things tease a tiny bit on the morning of Wednesday the 9th. The swell picks up to a whole 1ft from the south, and the wind goes glassy. That’s the cleanest window we’ll see in the first week, but with only 7 units of energy, it's barely enough to get you wet. Afternoon sees the wind swing onshore again.

Thursday the 10th through Sunday the 13th, the swell bumps up slightly to 1ft - 2ft from the south-southeast, but the wind is a constant cross-onshore or onshore mess. It’s choppy and poor. The energy is still low, hitting 29 on the 13th which is the best of the bunch, but it’s still weak.

From Monday the 14th onwards, it’s a slow slide back down to nothing. We get a tiny glassy window on the morning of Tuesday the 15th with 1ft, but it’s fleeting. The last week is just flat, with 0.3ft to 1ft and onshore winds.

The Standout (and I use that term loosely):

If you are absolutely desperate, the morning of Wednesday the 9th of September is your best bet. The swell is tiny at 1ft from the south, but the glassy, offshore wind (SW) will make it smooth. It’s the only clean session in the whole run. The water temperature is a touch warmer than normal at 87°, which is a nice bonus.

The Bottom Line: This is a long, flat spell. There's nothing here for experienced surfers. For a beginner at Octagon House, you might get a few tiny, clean waves on the 9th morning, but that’s it. The breaks are fairly consistent, but the swell just isn't showing up. Forecasts can change, but right now, it’s a waiting game.

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.
