The Lowdown

Alright folks, Rusty here. Let's get straight into it.

The next couple of weeks are a bit of a mixed bag for E-Bay. We've got consistent swell running, but a lot of stormy weather and wind to wrestle with. It's not all bad though, there's a little window of clean conditions that looks like the pick of the bunch, if you're patient.

We start off on Thursday the 10th and Friday the 11th with a solid SSW groundswell, offering 3ft to 4ft sets. The problem is the wind is blowing straight onshore at 12 to 16 mph, and there’s the risk of thunderstorms. The water's warm, sitting at 85°, which is pretty normal for this time of year. But honestly, the first few days are a write-off—rough and messy. The combined energy is actually moderate to strong, hitting 782 on Thursday afternoon, but it's all wind-chop and poor form. Not worth paddling out.

Saturday the 12th shows a bit of promise but still falls short. The swell bumps up a touch, with 4ft in the afternoon off the SSW, and the period is a very long 19 seconds. This kind of groundswell loves a reef like E-Bay, and the energy jumps to 1525 (strong). But the wind is still onshore or light, and we’ve got that "marginal" label. The conditions just aren't there. This pattern of onshore wind, storm risk, and marginal surf holds through to Tuesday the 16th, with heights staying around 4ft to 5ft.

Now, here’s where things get interesting. After a long run of poor conditions, Wednesday the 23rd morning is the real standout. The wind goes glassy—dead calm, 0 mph from the SSW. The swell is a clean 4ft from the south, with a 16-second period. The energy is solid at 904 (moderate-strong). For the first time in this forecast, we get "very good surf conditions" and a 3/10 score. If you can wait that long, that Wednesday morning is your golden ticket. It’ll be clean, lined-up, and not too big for most surfers. The window is tight though, as the afternoon brings cross-onshore wind right back.

Beyond that, the final few days on the 24th and 25th settle back into onshore breezes and smaller, shorter-period swell. The energy drops back to moderate. Nothing special there.

So, the clear winner here is the morning of Wednesday, 23 September. Don't get too excited about the weeks before. It’s a long wait, but that glassy window looks like the one to aim for.

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.
