The Lowdown

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

Right off the bat, I gotta be straight with you – it’s a tough stretch. The guidance is pointing to Octagon House as the only spot on the radar, and honestly, for the next 16 days, the surf is looking pretty flat. We’re looking at a long, dry run with barely a ripple worth mentioning.

The first record shows Tuesday, August 11, with a tiny 2 ft SSE swell, but the wind is a cross-on 9 mph from the SSE, and it’s just choppy and poor. The water is a warm 87°, running about a touch warmer than normal for the time of year, which is nice for a dip, but not for surfing. The combined energy is a weak 22. That’s nothing.

We roll through Wednesday the 12th and Thursday the 13th, and it’s more of the same: 2 ft to 3 ft of short-period, weak SSE windswell, with cross-on breezes keeping it messy. The energy never gets above 61. Friday the 14th and Saturday the 15th are still poor, with the swell peaking at 3 ft but the wind is onshore, making it a washout.

Now, Sunday the 16th has a moment – glassy conditions in the morning with zero wind. That’s a tease. But the swell is only 2 ft with a period of 6 seconds, and the energy is a weak 23. It’s flat, it’s clean, but it’s not surfable. From there, it just fades. Monday the 17th through to the end of the period, we’re talking 1 ft or less, with periods of 4 to 6 seconds. The energy drops to single digits by the 21st. By the 22nd of August, we’re down to less than 0.5 ft, and it stays that way until the 26th.

There’s no standout. No one day to circle on the calendar. The whole 16-day window is a bust. This is a blank run, and for this area, it’s pretty normal when the swell just doesn’t show. Don’t bother paddling out – you’d be better off stretching on the sand.

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.
