Alright, this is Rusty. Let’s have a look at what’s cookin’ for E-Bay over the next couple weeks.
First things first – we’ve got a bit of a quiet start. The first real shout for a paddle comes on Wednesday morning, July 8th. We’re looking at a solid 4ft groundswell out of the south, with a very long 15-second period. The water’s sitting at 86°, which is about average for this time of year. That deep, long-period energy is bringing plenty of push with a combined energy reading of 773 (moderate wave energy). And get this – the wind is glassy, right out of the NE at just 3 mph. That’s a recipe for clean, lined-up sets on the reef. The crowd can be a factor here sometimes, so get in early. This is the standout of the early period.
The next few days get a bit messy. Thursday and Friday see the wind turning onshore and cross-onshore, and the surf quality drops right off. It stays pretty marginal through the weekend and into the start of the following week. There’s still swell around, but the wind just isn’t playing ball, leaving things choppy and uninviting. We’ve got a real dry spell here for several days with no good options.
Now, if you can hold out, there’s some real promise showing up further out. On the morning of Sunday, July 19th, things start to look interesting again. The swell is back to 4ft from the south, with a super long 18-second period, and the combined energy jumps to 1302 (strong wave energy). The wind goes glassy again – just 3 mph from the SE. That’s going to be clean and pushy, though with that long period, it might be a little too straight for a beach break, but on a reef like this, it should be firing. This is your second standout.
The crown jewel might be the morning of Tuesday, July 21st. We’re looking at 6ft of south swell with a 17-second period and a combined energy reading way up at 1815 (very strong wave energy). The wind is glassy again from the ESE at 3 mph. That’s a serious groundswell. It’s pushing over 5ft, so it’s probably a bit much for the beginners, but for advanced surfers, this is looking excellent. Keep an eye on this one as we get closer.
The end of the period on July 23rd also has some clean, glassy mornings with 4ft south swell and solid 13-second period, so it’s finishing on a high note.
So to wrap it up: the early action on Wednesday morning July 8th is your best bet in the first week. Then a long quiet stretch. If you’re patient, Sunday July 19th morning looks good, and Tuesday July 21st morning is the big, powerful standout – promising but a little far off, so stay tuned.
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.
