The Lowdown
G’day, Rusty here, and I’m looking at what’s on offer at E-Bay over the next couple of weeks. I gotta be straight with you – the start is pretty grim. For the first four days, from Monday the 14th through to Thursday the 17th, it’s all onshore wind and sloppy, poor surf conditions. The swell’s around 4ft to 5ft from the SSW, with moderate energy, but the wind’s ruining it. Not worth paddling out.
Friday the 18th is a write-off as well – swell drops to 3ft, still cross-onshore and choppy. So, we’ve got a solid six-day gap of no-go surf here.
Now, things change on Saturday the 19th. That’s your first real standout. Early morning sees a glassy, clean window with a solid 4ft SSW groundswell, and hold on – the period is 18 seconds, long and juicy. The combined energy is strong (1567), and those conditions are excellent for experienced surfers. The water temp is 85°, which is about normal for this time of year. The offshore wind is from the WSW at just 3 mph, so it’ll be silky smooth. Crowds can be an issue here at E-Bay (reef), so get in early. This is the best session in the first week.
After that, it’s back to onshore slop from Saturday afternoon until Monday the 21st afternoon – marginal at best, with 4ft to 5ft swell but poor wind.
Tuesday the 22nd drops right off to 2ft to 3ft, weak and not worth it.
Wednesday the 23rd through Friday the 25th is a run of poor conditions again – onshore winds and small, messy waves.
But then, keep your eye on the last weekend. Sunday the 27th sees a nice SSW swell building to 6ft to 6ft with a very long 20-second period (2610 energy), but the wind is onshore. Still, for experts, it’s got potential. The true standout in the second week, though, is Monday the 28th. Morning is cross-onshore, but by the afternoon it goes glassy with clean 5ft S swell at 16 seconds (1242 energy). That’s another excellent window for experienced surfers. After that, the swell fades through Tuesday the 29th.
Overall, the best windows are the morning of Saturday the 19th and the afternoon of Monday the 28th (over a week away, so check back closer to the date). If you’re a beginner, the 4ft to 5ft is fine, but the long period on the 19th might make it a bit peaky. For experts, those two sessions are where it’s at.
Catch ya out there, 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.
