The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for E-Bay over the next couple of weeks.
To be honest, the first week or so is a bit of a write-off. We’re looking at a real slow start with tiny, weak swell and poor conditions. From Thursday the 23rd of July right through to the end of the month, the waves are just not there. We’re talking about ankle-snappers at best, with a lot of onshore or cross-onshore wind messing things up. The combined swell energy is weak, sitting in the double digits (66 to 183) for most of that stretch. It’s a real bummer, but that’s the way it goes sometimes.
Now, things start to look much more interesting as we move into the first week of August. There’s a real shift in the pattern.
The Standout: Tuesday, August 4th
This is the one to circle on the calendar. The morning of Tuesday the 4th is looking like the pick of the entire forecast. E-Bay is a reef break, so it handles that long-period groundswell well. We’ve got a solid 5ft of swell pumping in from the S, with a period of 16 seconds. That’s proper groundswell, folks. The combined energy is strong, clocking in at 1303. But the best part? The wind is glassy. Absolutely dead calm. That means the wave faces will be like a mirror. This is prime for experienced surfers, as it’s a solid 5ft with plenty of punch. The offshore wind is listed as NNW, which is the optimum direction for this spot, so it’s going to be draining perfectly. Expect a bit of a crowd, as it’s a spot that can get busy, but for those few hours, it’ll be worth it.
The Build-Up: Saturday, August 1st & Sunday, August 2nd
Before that standout day, we’ve got a great run of building swell. Saturday the 1st of August is glassy with a clean 3ft from the SSW, and by Sunday the 2nd, we’re up to 3ft from the S but with a very long 19-second period, giving it some serious grunt. The energy is strong (826 and 885). The wind is light and glassy, so these mornings will be clean and fun, though the sets will be a bit more spaced out with that long period.
The Solid Run: Monday, August 3rd to Thursday, August 6th
Monday the 3rd holds in with a 4ft swell and glassy conditions, and by Tuesday the 4th we hit that peak. Wednesday the 5th and Thursday the 6th are still packing a punch. Wednesday is a bit smaller at 3ft but with a clean offshore breeze from the N, and Thursday bumps back up to 5ft with a clean cross-offshore wind. Both of these days are solid, but the real magic is on that Tuesday.
So, to sum it up: suffer through the first week, it’s a bust. The real action starts on the 1st of August and runs through the 6th, with Tuesday the 4th being the absolute standout. Get out there if you can.
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.
