The Lowdown
Alright, Rusty here with a look at what’s coming our way. Let’s be straight up—this isn’t a classic E-Bay run. We’ve got a window of something rideable, but it’s going to take some patience and a good eye on the conditions. The water temp is sitting at 85°, which is about average for this time of year.
The first few days, honestly, are rough. Monday the 24th into Tuesday the 25th, we’ve got poor to marginal surf with onshore winds and that 3ft to 4ft range of 15-16 second swell from the south. The combined energy sits around 793 to 661—that’s moderate energy, but the wind is just a killer. Not worth paddling out for.
The real flicker of hope comes Wednesday morning, the 26th of August. It’s small, only 3ft, but that swell is pushing from the SSW at 13 seconds, and the wind is glassy. Glassy, mate. That is the standout here. The energy is 334, still moderate, but the clean surface makes those little reef lines at E-Bay look real inviting. It’s the best of a quiet period. But be warned, this break can get a crowd sometimes, so get in early.
Then Thursday the 27th, the swell picks up a bit—5ft from the SSW by the afternoon with a very long 18-19 second period. That’s groundswell territory, and on a reef setup like E-Bay, that’s going to produce some nice, powerful lines. The combined energy jumps to 1226, which is strong wave energy. The catch is the cross-onshore wind from the SE, so it’ll be a bit bumpy, but still the second-best window we’ve got. It’s still in the marginal category, but a quality surfer will find something.
After that, Friday the 28th gets choppier as the wind picks up, and we slide into a long gap. From Saturday the 29th all the way through to Sunday the 6th of September, it’s mostly poor or marginal surf with onshore winds and small, weak swell. There’s a day around the 1st of September where the swell hits 5ft from the SSW again, but with the onshore wind and energy around 1223, it’s just messy. The period between Saturday the 29th and Sunday the 6th is a solid week with no proper recommendations. After that, the 8th of September just fizzles out again.
So, the best on offer? That Wednesday morning 26th with the glassy, clean 3ft SSW lines—it won’t be big, but it’ll be clean. The strong, long-period groundswell on the afternoon of the 27th is a close second if you don’t mind a bit of cross-onshore texture. That’s your window. Everything else is a skunk.
Stay sharp, and check the wind before you go.
Rusty.

Information about the E-Bay Surf forecast
The above surf forecast table for E-Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at E-Bay can be found by selecting the local surf guide option on the grey menu. Our E-Bay 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 (E-Bay) 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 E-Bay 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.
