The Lowdown
Alright, this is Rusty. Let’s have a proper look at the charts for the next couple of weeks.
We’ve got a solid run of surf coming in for E-Bay, but it’s not for everyone. The first few days are the real deal, with clean, powerful groundswell and light offshore winds that will have the place looking mint. After that, the wind turns onshore and things get messier, though there’s a late window of cleaner conditions that might be worth waiting for.
The water temperature is sitting right around average for the time of year, so nothing strange there.
The standout period kicks off Thursday 6th August with a solid 1.6m (5ft) swell from the south, a very long 17-second period, and a moderate N to NNW breeze keeping it offshore. The combined energy is a beastly 1500 – strong wave energy. It’s a reef break, so with that long period, expect clean, lined-up sets at E-Bay. This is advanced territory, 1.6m (5ft) is getting up there, but it’s not too big for experienced surfers. Crowds are sometimes an issue here, so be ready to share.
Friday 7th August is the real highlight. The swell bumps up to 1.8m-1.9m (6ft-6ft) from the south, period still a long 17-18 seconds, and the wind drops to a gentle offshore breeze. The combined energy is even bigger, hitting 2182 and 2282. This is the best you’ll see in the whole outlook – clean, powerful, and consistent. If you can only get out one day, make it Friday.
Saturday 8th August still has good energy, 1.7m-1.8m (6ft-6ft) south swell with a 16-second period, but the wind swings to a light cross-offshore. Still clean enough for a good session, but not as glassy as Friday. The energy is still strong at 1442-1691.
Then from Sunday 9th August through to about Wednesday 13th August, the wind turns onshore from the southeast, and the wave quality drops. The swell sticks around, sometimes even getting bigger, hitting 2.3m (8ft) on the 11th (combined energy 3830 – very strong), but with onshore wind it’s going to be choppy and hard to enjoy. For a beach-and-reef setup like this, with that much wind and swell, it might actually be more interesting for kite surfing than paddle surfing.
Thursday 13th August afternoon sees the swell drop right off, and the next few days are small and poor. The energy drops to 183 and then lower, with barely any rideable waves. There’s a gap of poor surf from the 13th through the 17th.
Wednesday 19th August is a late bright spot. The swell comes back up to 1.7m (6ft) from the SSW, with a 17-18 second period, and the wind goes glassy in the afternoon. The combined energy is 1732 – strong. That afternoon glass-off session on Wednesday 19th is the second best call of the whole outlook. It’s clean, it’s got power, and it’s for experienced surfers.
After that, the 20th and 21st have more onshore wind and the quality drops off again, with a 2.0m (7ft) south swell on the 21st but blown out.
So, to wrap it up: the best surf is Friday 7th August – clean, powerful, and consistent. The second best is the glassy afternoon of Wednesday 19th August. Outside of those, the first week has some good windows, but the second week is mostly a write-off until that late glassy swell.
Stay safe out there.

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.
