The Lowdown

Alright crew, Rusty here. Let’s be straight with you – the forecast for the next two weeks at Octagon House is a real struggle. We’re looking at a long, flat spell with hardly any energy to speak of.

The first few days, from Saturday the 29th of August right through to the morning of Friday the 4th of September, are a total write-off. Swell is tiny, at best 1ft, with short periods and no power. The wind is mostly onshore or cross-on, and the surf is just flat and messy. The water temp is sitting at 87°, which is a touch warmer than normal for this time of year, but that’s not going to make the waves any better.

The only faint glimmer of something arrives on the morning of Saturday the 5th of September. We get a tiny bump to 3ft from the ESE, but the real kicker is the wind: it’s glassy, dead calm. The combined energy is still weak at just 20, so it’s barely a ripple. You’ll be on a longboard or a foamie, maybe having a laugh, but don’t expect anything proper.

Through the second week, the swell stays anemic, mostly 1ft to 3ft, with the wind almost always ruining it. The combined energy does climb into the moderate range on the 9th of September, hitting 269, but that’s with a 5ft cross-on slop coming from the SSE. The wind is blowing 16 mph, so it’s going to be lumpy, choppy, and a complete mess. That’s not surf for a paddle board; that’s kite-surfing territory if you’re into that.

Honestly, there’s nothing here worth paddling out for. This is a blank run, and for this area, it’s pretty normal to have these long flat spells. Stick with it, though – it won’t stay poor forever.

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.
