The Lowdown
Alright, let’s get real about E-Bay. This is a reef break, exposed to the west swell window, and it’s fairly consistent. The water temp is sitting at about 85°, which is about average for this time of year, so nothing freaky there.
Right now, we’re looking at a pretty grim start. The first recommendation doesn’t come until Thursday morning, the 27th of August, but honestly, that’s a write-off. We’ve got a 3ft SSW swell, with a long 19-second period, but the wind is onshore from the SE at 6 mph and the energy is only moderate (969). The comment says it’s marginal, and I’m with that – it’s a pass.
Thursday afternoon is similar, with 5ft SSW swell, but still onshore wind. Friday the 28th morning is the same story: 5ft SSW swell, but cross-on wind. The whole weekend and into early next week is a bust. From Friday afternoon all the way through Sunday the 7th of September, it’s one “poor surf conditions” call after another. There’s a long dry spell here with no real windows to surf.
You get a little tease on Tuesday the 8th of September morning, with a glassy 1ft SSW swell, but it’s tiny. The energy is weak (72), but at least the wind is calm. It’s only for the brave on a longboard. That glassy, clean surface is a positive, but the swell is just too small to get excited about. Wednesday the 9th is similarly tiny and glassy.
Now, eyes on Thursday the 10th of September afternoon. That’s the standout. We’re looking at 4ft SSW swell, 17-second period, and glassy conditions with ESE wind at only 3 mph. The comment says it expects very good surf. The combined energy is moderate (689), but that clean, glassy face with a long-period groundswell will make E-Bay’s reef lines really stand up. The swell direction (SSW) isn’t the absolute optimum (which is W), but it’s close enough, and with those conditions, it’s your best bet. It’s a bit further out, so treat it as promising but not locked in.
Don’t get too hopeful for Friday the 11th – it’s back to cross-on wind and marginal conditions.
So, to sum it up: we’ve got a rough first week, a long gap of nothing, but if you can hold out for Thursday afternoon the 10th of September, you might just score some clean, long-period lines at E-Bay. That’s the one window worth chasing.

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.
