The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for E-Bay, and honestly, we’ve got a bit of a mixed bag coming up. The first few days are the real deal, but after that, it’s a long stretch of pretty ordinary, onshore slop until the very end of the window. Let’s get into it.
The standout window kicks off on Wednesday, 26 August, with some glassy, clean conditions. The morning session is the pick of the whole period: the wind is glassy, the water is a warm 85°F which is about average for this time of year, and we’ve got a clean 3ft south swell rolling in with a solid 13-second period. The combined energy is moderate at 393, but it’s that morning stillness that makes it special. Afternoon sees a tiny drop to 3ft from the SSW, still glassy, but with a risk of thunderstorms. This is your best chance for a fun, uncrowded wave, though it’s a reef break so watch the shallow bits.
After that, the wind shifts onshore from Thursday, 27 August, and it’s a long grind. The swell actually builds nicely—hitting 5ft on Friday morning (28 August) with a very long 16-second period from the SSW, and the combined energy gets strong at 1049—but the onshore wind just ruins it. The surf is marginal at best, and by Friday afternoon with a 12 mph onshore breeze, it’s a mess. This pattern of onshore wind and choppy, poor surf continues right through to Monday, 7 September. There are a few moments where the energy stays high—like Monday, 31 August, with 4ft at 18 seconds and 915 energy—but it’s all blown out. This setup is honestly more interesting for kite surfing than paddle surfing if you’re into that.
The light at the end of the tunnel comes on Wednesday, 9 September. The morning is glassy again, with a clean 4ft SSW swell at a very long 17 seconds and strong combined energy of 745. The forecast calls for very good surf conditions, and I’m getting excited about it. Just keep in mind it’s a long way out, so don’t book your flights yet, but mark it in your calendar. There’s also a glassy, tiny 3ft bump on the morning of Monday, 7 September, but it’s barely surfable.
So, to sum it up: your two real standouts are Wednesday morning, 26 August, and the morning of Wednesday, 9 September. The first one is the sure bet, the second is the promising long-range hope. The rest of the 16 days is mostly a write-off with onshore winds and poor quality. But hey, it’s a reef break, and when it’s on, it’s on.
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.
