The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for the next couple of weeks.
Right off the bat, I gotta say, we’re in a bit of a flat spell to start. There’s no real surf on offer until Tuesday the 11th, so you're looking at a few days of staring at a lake. The only game in town is E-Bay, a reef setup that needs a solid west swell to really hum, and we're not getting that just yet.
The first real pulse shows up on Tuesday morning, August 11th. We've got a powerful 7ft S swell pushing in, with a very long 18-second period. The energy is pumping hard at 3599, so you'll feel the weight of it. But here's the kicker – it's blowing a moderate onshore breeze from the SSE at 12 mph. That’s gonna mess up the surface something fierce. For a reef break that likes clean conditions, this is a tough sell. The water temp is a warm 86°F, which is about 1°F above normal, so pretty average for this time of year. Honestly, this setup looks more interesting for the kite surfers than paddle surfing, given the strong onshore wind and solid swell.
That south swell hangs around through Wednesday the 12th, still a decent 6ft with 16-second period, but that onshore wind doesn't let up. It's a consistent pattern of "marginal" conditions. We see the swell drop right off Thursday afternoon, down to 1ft by Friday, with a risk of thunderstorms. Not much to write home about.
Now, the one true standout in this whole outlook arrives on Sunday morning, August 16th. The conditions finally align. We've got a 4ft S swell with a 15-second period – not huge, but with good shape. The wind goes glassy, dead calm at 3 mph from the NNE. The report says "expect very good surf conditions," and for a reef break, glassy is as good as it gets. This is the morning to be out there. The rip will be easy to read with that long period, just be aware it might break a bit straight on the reef.
After that brief moment of glory, it’s back to a long run of onshore wind and messy, marginal surf. The swell bumps up again around 5ft to 6ft from the SSW and then S from the 18th to the 22nd, but it’s always accompanied by a moderate sea breeze. There’s a slight improvement on Thursday the 20th afternoon, with a 6ft S swell at 18 seconds, and the energy jumps to 2831, but the wind is still onshore. The following week through to the 26th just looks like more of the same: average swell, average wind, nothing to get the heart racing.
So to sum it up: the best on offer is Sunday morning, August 16th at E-Bay. Get out there early, enjoy the glass, and forget about the rest of the fortnight. The crowds might be around at E-Bay, so expect some company on that peak.
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.
