The Lowdown
Alright folks, Rusty here with a look at what E-Bay has on offer for the next couple of weeks. We've got a bit of a mixed bag coming our way, so let's get into it.
The water temp is sittin' around 85°, which is pretty standard for this time of year – nothing weird going on there.
The next few days, starting from Saturday the 12th, are a bit of a write-off, to be honest. The swell's there, but the conditions are just messy. The wind is onshore or cross-onshore, and the descriptors are all 'marginal' or 'poor.' Some light morning ripples on the 12th with a 3ft swell from the SSW, but the period is a short 20 seconds, and the energy is moderate at 861. Not worth paddling out for. This poor run of onshore junk looks set to stretch right through until at least the end of the week.
You'll be wanting to wait for the 22nd of September, mate. That's the standout window in this forecast. The Tuesday morning is looking choice – glassy conditions with a lovely 3ft swell from the S. The period jumps to 20 seconds, which is some proper long-period groundswell, and the energy is strong at 1492. This is the kind of clean session you wait for. Just keep in mind that long period swell like this can break a bit straight at some beach breaks, but at E-Bay, a reef setup, it should form up nicely. There is a chance of a storm, but if it stays glassy, it'll be magic. It's an advanced-level break, so be ready for it. Also, the crowds can get in there sometimes, so get there early.
Following that, Wednesday the 23rd is still looking tidy. The morning is glassy again with swell from the S at 5ft and a 16-second period, strong energy at 964. The afternoon is forecast to be glassy with a 4ft S swell, though the energy drops a bit. Both sessions are looking real good for experienced surfers.
Into the last week, things get a bit more uncertain. The 25th of September has a building swell from the S, hitting 6ft by the afternoon with a 19-second period and massive energy at 3330. That's a lot of water moving, but the wind is a cross-shore, so it'll be a bit wonky. The 26th has a similar story, with solid 7ft S swell but onshore winds. For the experienced lads, the size and power are there, but the wind is going to mess with the shape.
For the rest of the period, it's a lot of onshore wind and 'marginal' or 'poor' labels. Not much to write home about after the 23rd, but that Tuesday the 22nd is the real gem to aim for.
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.
