The Lowdown
Alright, grab a coffee and settle in, it's Rusty here with a look at what's on the cards for the next couple of weeks. We've got a classic late-season run of southern groundswell on the way into E-Bay.
We kick off Friday, August 7th, with some serious energy. A solid 6 ft S swell, with a period of 18 seconds, is pumping. The combined energy is a hefty 2268, which tells you there's plenty of power in the water. Early on a northerly breeze keeps it clean, but it's a bit cross-off. By the afternoon, the wind swings to the NNW and goes offshore, really cleaning up the lines. This is quality, but it's a reef break, so it's strictly for experienced surfers. The water temperature feels about average for this time of year for the first spot.
The real standout window opens on Saturday, August 8th. The swell holds around 6 ft to 6 ft from the south, with a period of 16 seconds. The morning is clean with a slight cross-off breeze, but the real magic happens in the afternoon. The wind drops to a glassy 3 mph out of the ENE, and the waves are described as "glassy." That's as good as it gets. The energy is still strong at 1424, and the offshore wind direction matches the optimum for the break. This is the pick of the first week, hands down.
Sunday, August 9th, the wind turns onshore from the SE and SSE, putting a bit of chop on the surface. The swell is still there at 6 ft, but the quality drops. The following week, from Monday the 10th through to Wednesday the 12th, the wind stays onshore, and the surf gets lumpy and messy. The swell remains solid, peaking at 7 ft on Tuesday the 11th with a massive energy reading of 3580, but with the wind on it, it's a battle. That size is only for experts anyway, and the conditions make it a tough paddle.
We hit a real lull from Thursday, August 13th, through to Friday, August 14th. The energy drops right off into the double digits, and the swell is barely a ripple. Just a quiet spell.
Then we see a pulse of life return on Saturday, August 15th. The morning brings a clean 6 ft swell from the south with glassy conditions, but it fades quickly. The afternoon is a dud, so it's a short window.
The next real event to get excited about is a week away, on Tuesday, August 18th. The morning delivers a glassy 5 ft S swell (1654 energy) and a perfect 17-second period. This is clean and promising, but it's in the long-range, so keep an eye on it.
The absolute standout of the whole forecast window is Wednesday, August 19th. We're looking at a 8 ft south swell, with a period of 18 seconds, and glassy conditions all day. The combined energy is over 3500. This is a serious, powerful, clean groundswell. It's a big one for the experts, but for those with the skills, it's going to be firing. This is the one to circle on your calendar.
After that, the wind gets messy again from Thursday, August 20th, through to Saturday, August 22nd, with moderate onshore breezes and a dropping swell in the 6 ft to 7 ft range. The run fizzles out into a bit of a lumpy end to the outlook.
So, the big call: Saturday, August 8th, for the perfect glassy conditions, and Wednesday, August 19th, for the raw power. 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.
