The Lowdown

Alright surfers, Rusty here. We're looking at the E-Bay reef for the next couple of weeks.

The long-range picture is a bit of a slow burn. We've got a lot of onshore wind and risk of thunderstorms gumming up the works for the first while, with some cleaner windows opening up further down the line. The best of the action looks like it's going to be in the second week, around the 22nd and 24th of September.

Right now, and for the next several days, it's a tough one. The best we can say is that the swell is there, but the conditions are keeping it messy. Thursday the 10th has some marginal swell coming in at 3 ft from the SSW with a decent 16 to 17-second period, but those onshore winds will make it a challenge.

The first real standout of the period looks to be Saturday the 12th in the afternoon. The wind is set to go super light from the SSE, dropping to just 3 mph, which should groom things up nicely. We're looking at a 4 ft SSW swell with a 19-second period. The energy is building, hitting a moderate 1393. This is one to keep an eye on, as glassy conditions on a reef are a rare treat, so get out there if it cleans up.

Moving into the middle of the second week, Tuesday the 22nd and Wednesday the 23rd of September start to look more interesting, but the wind will be a factor with cross-onshore breezes. The swell on the 22nd has a very long period of 20 seconds, but from the S, which can be a bit straight at times. The energy is moderate, with 1268 to 1399 for the swells that day.

The next real highlight is Thursday the 24th of September. The morning sees the biggest swell of the forecast at 6 ft from the S, with a solid 18-second period. That's solid groundswell energy, clocking in at a strong 2302. With light onshore winds from the SE, it's going to be bumpy, but there's power there. At 6 ft, this is getting into the territory where it's less for the beginners and more for the crew with some experience. This is the pick of the bunch, but treat it as a promising long-range call – keep your fingers crossed the wind gods play ball.

For the Tuesday the 22nd and Wednesday the 23rd windows, the winds are light and cross-onshore, so it's not going to be pristine, but there's enough energy with a long period to make it work, especially if you can find a peak that's a bit more sheltered. On the Thursday the 24th, the swell is from the S and the wind is also from the S, so it's going to be onshore, but with that much power and period, there will be waves to be had if you can handle the bump.

Water temp is sitting around 85°, which is about average for this time of year.

This is Rusty, signing off.

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.
