The Lowdown
Alright, Rusty here. Let's talk about what we’ve got coming up at E-Bay. It's a bit of a slow burn, but there is some real magic on the horizon if you're patient.
We're looking at a real mixed bag to start. The opening is pretty grim, to be honest. Friday the 28th kicks off with a small 4ft SSW swell, but the wind is on it and the energy is weak, so it’s barely on the radar. The whole weekend of the 29th and 30th is a write-off with poor surf and risk of thunderstorms, so don't even bother.
The first few days of September are still feeling the hangover from that. Monday the 31st and Tuesday the 1st see the swell bump up a touch to 5ft, but it’s still a "marginal" call with onshore breezes and moderate energy. Wednesday the 2nd through Friday the 4th morning are flat and windy. There's a tiny window on Friday afternoon the 4th when the wind goes glassy and the 3ft swell from the SSW shows some life, but it’s only a flicker.
Now, here’s where it gets interesting. The real standout is shaping up for the second week. Everything comes together beautifully. From the 9th of September right through to the 12th, the winds finally swing offshore or go glassy. This is a rare treat and will make the waves clean. The swell direction stays solidly SSW with periods climbing up to 16-18 seconds. That’s proper groundswell, meaning long lines and lots of energy. The combined wave energy is going to be impressive, hitting a huge reading on Saturday the 12th – that's a lot of power behind waves that will be pushing 5ft.
That Saturday the 12th afternoon is your absolute standout. Clean, glassy conditions with a solid 5ft SSW groundswell and ridiculous energy. That's expert territory at that size and power for a reef break, but man, it will be worth the wait if you’ve got the skills. The entire run from the 9th to the 12th is looking promising, with the 9th and 10th also offering clean, offshore conditions with 3ft to 4ft of that long-period SSW swell. That's more user-friendly but still excellent quality.
A quick note on the water: when you paddle out at E-Bay, the water temp is sitting at a balmy 85°, which is about what you'd expect for this time of year. No wild anomalies to worry about.
So, skip the first week and a half. Clear your diary for that Thursday the 10th through to the 12th. The best of the best is that Saturday the 12th afternoon.
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.
