The Lowdown

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

Alright, straight up – I’m not gonna sugar-coat it. There’s a proper flat spell on the cards. The first few days are a write-off for any kind of paddle surfing. You’re looking at a solid week of nothing worth talking about, from Monday the 17th of August right through to the end of the month. The swell is tiny, the period is short, and the wind is mostly cross or onshore, just chopping everything up. It’s a real bummer. The only thing that’s got a bit of life is the *combined energy of all swells directed here*, which barely hits double digits most days – typical weak energy (15-26). Water temp is about average for the time of year, so no surprises there.

The one bright spot in this whole outlook is a few days around the end of the month. Monday the 31st of August morning, we finally see a little pulse. The swell bumps up to a tiny 3 ft from the ESE, with a period of 5 seconds. The *combined energy of all swells directed here* is still weak at 34. But the wind is light from the SW, so it’s a light cross-shore with just small ripples. It’s not going to be a classic, but it’s the best we’ve seen in a while.

Then Tuesday the 1st of September morning, the swell is 3 ft from the ESE, period of 6 seconds, and the *combined energy of all swells directed here* is 43. Winds are light from the SSE, so a light cross-onshore with small wind ripples. It’s still poor surf conditions according to the data, but it’s the only thing that’s not completely flat.

The spot is Octagon House. It’s a beginner-friendly, fairly consistent break that’s exposed to the SE swell. Crowds are possible here sometimes. The optimum swell direction is from the SE, and the swell we’re getting is from the ESE, so it’s a bit off-angle but still workable. It’s a beach break, but with these tiny waves, it’s just about getting wet.

Look, honestly, there’s no standout session here. The only real takeaway is that the blank run is pretty normal for this area. But don’t lose hope, forecasts can change. For now, the board stays in the car.

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.
