The Lowdown
Alright, Rusty here again. Let's be straight with you – the next week to ten days is going to be a proper battle of a surf. It's all slop and chop, the sort of conditions that test your patience more than your pop-up. The ocean has some energy, but the wind is just going to be ruining it most of the time.
From Wednesday the 16th to Thursday the 24th, it's pretty grim. We've got surf in the 3ft to 5ft range but it's all onshore, a mix of S and SE winds just raking it out. It's weak energy too, mostly reading in the 300-900 range, which means it's all noise and no power. We get a couple of pulses mid-week, like on the 19th and 20th where the energy gets up to 1060 and 1340, but it doesn't matter 'cause the wind is still on it. It's a full stretch of junk.
We see a big jump in size for the weekend of the 26th and 27th. The swell spikes up to 2.0m on Saturday afternoon, and the energy reading is going off the charts at 3102. But again, it's onshore, and we've got some rain, so it's going to be big, raw, and pretty much unsurfable for the average punter. This is big-muscle, heavy-water stuff for experts only. Sunday is similar, with 2.2m on the morning but still choppy and cross-onshore. We're talking all grunt and no glory.
Now, here's the light at the end of the tunnel. The standout, and I mean the only real standout of the whole 16 days, looks like the morning of Wednesday the 30th of September. This is the one to wait for. The swell has backed off to a clean 4ft to 5ft from the S, but the wind is finally offshore and light, out of the NE. That's the recipe for E-Bay (a reef break) to clean up. The period is a workable 13 seconds and the energy is still strong at 1023. This is the only time in the forecast where you'll find a clean face from the start. Mark it in the wax.
Earlier, the morning of Saturday the 26th deserves a mention just for its size and power, with a 20-second period. But with that onshore wind, it’s going to be a nemesis, not a playground.
Water temps are at 29°, which is about right for this time of year, so boardies are the go. But don't get too complacent – conditions have been so poor for so long that it’s easy to forget what a decent wave feels like. The long-range call for that Wednesday is promising, but it's a long way out, so we just gotta keep our fingers crossed. Rusty, signing off.

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.
