The Lowdown

Alright, grab your coffee and settle in. Look, I’m gonna be straight with you—this next stretch is a proper flat spell. We’re looking at sixteen days with basically nothing rideable. It’s one of those classic late-summer lulls where the ocean just takes a nap. There’s a gap of no worthwhile surf from now all the way through to the end of the month, so don’t hold your breath.

Let’s start with the pick of a very, very thin bunch—and even that’s being generous. The only name on the board is Octagon House. It’s exposed to a SE swell, which is what we’ve got sliding in, but it’s tiny. The best of it shows up on the morning of the 16th at 2ft of SSE swell with a weak period of 6 seconds. The wind is glassy, light ESE at 3 mph, so the surface would be clean as a whistle. The combined energy is barely a whisper at 22—basically a ripple. Water temp is 86° with an anomaly of 2°, so it’s a touch warmer than average for this time of year. That’s about the only bright spot.

After that morning session, the winds pick up from the SE at 12 mph, blowing straight onshore, and the quality goes out the window. It gets messy fast. By the 17th, the swell drops to 2ft with a period of 6 seconds, and the wind is cross-off early but quickly turns onshore. Still no power.

From the 18th onward, it’s just a slow bleed. Swell hangs around 0.7ft to 2ft but the wind is mostly cross or cross-onshore from the south, often 12 to 19 mph. That’s not paddle surf—that’s kite weather, if anything. The combined energy never hits even 40 (39 is the peak on the 22nd afternoon). Periods are short, mostly 4 or 5 seconds, so there’s no push.

By late August and into the first day of September, it’s dead flat: 0.7ft on the 30th, 1ft on the 31st, with periods of 3 to 7 seconds. The wind goes glassy again on the morning of the 30th, but there’s nothing to ride. Honestly, if you’re itching to get wet, bring a prone paddleboard or just go for a swim.

This is a blank run, plain and simple. It happens.

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.

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.
