The Lowdown
G’day, Rusty here. The outlook for E-Bay is a bit of a mixed bag over the next couple of weeks. There’s surf on offer straight away, but the conditions are tricky initially. The water temp is about average for this time of year.
We start this Sunday morning, August 9th, with a solid 5ft S swell, but the wind is howling onshore from the SE at 12 mph, so it’s going to be rough with poor surf. Combined energy is strong at 1378. That afternoon drops a touch to 5ft, still onshore, still marginal.
Monday morning, August 10th, the swell holds around 5ft from the S with a 14-second period, but the SE wind stays onshore, so it’s still messy. Total energy is 1770. The afternoon sees a long-period 20-second groundswell at 5ft, but the wind goes cross-onshore from the S, leaving the surface choppy.
Tuesday morning, August 11th, brings the biggest swell of the week – 7ft from the S, with strong energy (3580) – but it’s cross-onshore. That’s big and bumpy, likely too big and messy for all but experienced surfers. Afternoon drops to 7ft, still onshore, still disappointing.
The rest of that first week into the second sees a drop in size and persistent wind issues. By Thursday, August 13th, we’re down to 3ft, and Friday turns glassy but tiny, with only 0.7ft to 1.0ft of swell. That’s a dead period.
Saturday morning, August 15th, things finally line up. The swell is small at 3ft from the S, but it’s glassy, with light wind and combined energy at 621. The forecast says “expect very good surf conditions”. It’s small, but the cleanest we’ve seen.
Now, if you can hold out, the real standout arrives Thursday afternoon, August 20th. The swell hits 6ft from the S, with a 16-second period, and it’s glassy – zero wind. Energy is strong at 1696. That’s excellent surf for experienced surfers. E-Bay is a shallow reef that breaks best on a W swell direction, so this S/SW direction isn’t its absolute optimum, but the clean conditions and solid size make it easily the best session on offer. Crowds are possible here, so get in early.
After that, the swell fades a bit through the last few days of the outlook, with size hovering around 4ft to 5ft, and wind mostly onshore or cross-onshore, so nothing else stands out.
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.
