The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day window, but don’t get too excited just yet—the first week is a bit of a write-off. It’s a slow start, but things are shaping up for a real gem later on.
The overall pattern is dominated by a long, drawn-out period of messy, onshore wind and stormy conditions. For the first several days, we’re seeing a lot of easterly and southerly winds blowing straight onshore, making a mess of things. The swell is there, but it’s not worth paddling out for. The first real chance of anything decent doesn’t show up until Thursday, September 3rd, and even then it’s just a small window.
E-Bay is the only spot on the menu, and it’s a reef break that is fairly consistent. Water temp is sitting at 86° with a 1° anomaly, so it’s a touch warmer than average for this time of year.
The standout of the entire forecast is the morning of Wednesday, September 9th. This is the one to circle on the calendar. We’ve got a clean 5ft swell from the south, with a period of 16 seconds—that’s proper groundswell energy. The wind is glassy, dead calm, with a slight air. The combined energy is strong at 1126. This is going to be clean, lined-up, and proper for experienced surfers. The reef setup will handle that long period beautifully. The swell direction is SSW, which is close to the optimum west direction, so it’ll wrap in nicely. Expect a few guys out, but it shouldn’t be a zoo.
The afternoon before, Tuesday, September 8th, is also worth a look. The swell bumps up to 5ft from the south at 17 seconds, with very light winds. The combined energy is even higher at 1414, but the conditions are listed as marginal due to tide. Still, it’s a strong option if you can work the tides.
After that, the swell stays around but the winds turn onshore again, so it’ll get bumpy. The weekend of September 12th and 13th drops off into poor territory again.
So, to sum it up: the first week is a dud. Wait it out. The real prize is the morning of Wednesday, September 9th at E-Bay. That’s your best bet for a clean, powerful session. The longer range into the second week is a bit of a gamble, but that one day is a solid promise.
Stay stoked, keep your eyes on the horizon.
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.
