The Lowdown
Alright, let’s get into it. We’re looking at E-Bay, and the start is pretty dead. The 29th and 30th of July? Tiny, weak swell and bumpy water. Not worth paddling out.
Now, come the first week of August, it gets better. The morning of Tuesday, August 4th, we’ve got a 4ft south swell with a 16-second period – that’s real groundswell. Water temp is about 85°, which is normal for the season. What makes this one good is the glassy wind. Clean, smooth conditions. Wave energy is moderate at 880 (combined energy). It’s not huge, but for the advanced surfer, it’ll be fun and clean. The reef isn’t getting its perfect west swell, but the quality of the wind will make up for it. Might be a few other folks out – crowds are possible.
The real highlight, though, is Wednesday, August 5th and Thursday, August 6th. On Wednesday afternoon we see the swell at 3ft but the period jumps to 20 seconds – that’s a very long period groundswell. Strong energy at 1234 (combined energy). Offshore northwest winds keep the faces clean. Thursday the 6th of August delivers 5ft south swell with 16-17 second periods and clean offshore north winds. Energy is pumping at 1302 to 1170 (combined energy). This is excellent surf for experienced surfers – the reef will hold that long period swell, giving you good shape and long walls. Not the ideal direction, but the quality is top-notch.
After that, things fall apart. August 8th and 9th get smaller and choppy with cross-onshore winds. By August 11th, it’s almost flat – 0.3ft to 1ft of weak, short-period junk. A few days of nothing. August 12th and 13th show some size again (4ft to 6ft) but the wind is onshore and the conditions are poor. Too much chop.
So, don’t bother before August 4th. Your best days are August 5th and 6th. Clean, solid swell for the experienced surfer. That’s the call.

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.
