The Lowdown
Alright folks, Rusty here. Let's have a look at what's brewing for E-Bay over the next couple of weeks.
Right off the bat, we're looking at a pretty flat start. The first few days are a write-off, with tiny, weak swell and cross-onshore winds creating poor surf conditions. From Tuesday, July 28th through to about Friday, August 1st, there's just nothing to get excited about. The swell is small, the energy is weak, and the wind is all wrong. It's a real bummer, but that's the way it is.
We do start to see a bit of life on Sunday, August 2nd, with a small bump in swell, but it's still pretty marginal. The real change starts to show up on Tuesday, August 4th. That morning, the wind goes glassy, and the swell is starting to get some legs. The waves are still only around 4 ft, but the energy is building (765), and that clean surface is a dream.
Now, the real standout window is from Wednesday, August 5th, through to Saturday, August 8th. This is where things get interesting. We have a solid, long-period groundswell from the South filling in. The wind goes offshore, which is perfect. On Wednesday, August 5th, the morning session is looking clean with offshore winds and a 4 ft S swell, with a very long period of 15 seconds and energy pumping at 942. The afternoon cleans up with a cross-off breeze but the swell period jumps to 19 seconds, sending energy through the roof at 1111.
But the best of the best? That's Thursday, August 6th, and Friday, August 7th. On Thursday morning, we’re looking at head-high plus waves at 5 ft from the S, with a 17-second period and a solid 1289 energy reading. The wind is a moderate offshore, keeping it clean. The afternoon gets even better – 5 ft, a 16-second period, and the wind goes light offshore. That’s your session. Friday, August 7th, is much the same story, with a 4 ft swell in the morning that jumps to 6 ft in the afternoon, with a 19-second period initially and then 18 seconds. The energy readings are massive, hitting 2439 on Friday afternoon. This is excellent, powerful surf, but with that size and power, it's really only for experienced surfers. The crowds are a possibility at E-Bay, so get out there early.
The rest of the outlook from Sunday, August 9th, onwards fades back into smaller, onshore conditions, so that window from August 5th to the 8th is the one to circle on your calendar. It’s a long way out, so don’t bet the farm on it, but it looks like a beauty.
Stay wet, stay hungry.
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.
