The Lowdown
Alright, let’s get into it. The long-range charts are showing a bit of a frustrating stretch for the next couple of weeks, but there are a couple of windows where things line up. We’re looking at a lot of onshore and cross-onshore wind, which is going to mess with the surface at E-Bay more often than not. The swell energy is there at times, but the wind and the tide are going to be the deciding factors.
The first few days are a write-off, honestly. The wind is going to be blowing on it, making things bumpy and messy. The swell is coming from the south with energy reading 1870, but it’s not going to be any good to ride. The water temp is around average for this time of year, so a thin suit is fine.
We get a bit of a pulse on Tuesday the 11th where the swell bumps up to 7ft 2in, and the energy is strong at 3581. The period is a solid 18 seconds, so there’s some push behind it. But the wind is still on it, so it’s going to be lumpy. It’s not going to be a classic, but it’ll be the best of a bad bunch early on. It’s a step up from the previous days, but still not worth rushing out for.
Then we hit a flat spell. Thursday the 13th and Friday the 14th are poor, with the swell dropping out and the energy reading just 176 and 57. There’s nothing doing. The wind is light, but there’s no waves.
The first real standout comes on Saturday the 15th. The morning is looking glassy with a light ESE breeze, and there’s a clean 2ft of south swell with an 18-second period. The energy reads 342. It’s small, but it’s clean and lined up. This is a long-period groundswell, so it’s going to be running down the reef at E-Bay nicely. It’s not big, but it’s the best wave you’ll see for a while. The crowds are listed as ‘sometimes’, so you might have it to yourself if you’re lucky.
After that, it’s a real mixed bag again. The swell tries to pick up mid-week, but it’s mostly onshore wind and the surface gets chopped up. The energy gets up to 2040 on Wednesday the 19th with a 5ft 9in SW swell, but the wind is ruining it.
The real standout of the whole period is Thursday the 20th. The afternoon session is looking glassy with a light SE breeze, and we’ve got a clean 5ft 3in of SSW swell with a 16-second period. The energy reads 1988, and the forecast is calling it “excellent surf conditions for experienced surfers.” This is a proper reef wave, and with that period, it’s going to have some real power and shape. This is the one to circle on the calendar. It’s still a fair way out, so don’t book the time off just yet, but it’s looking promising.
The final days of the window fade out with the wind going onshore again and the swell dropping off. The 23rd looks poor with a 4ft 6in swell but a moderate onshore breeze, so it’s not going to be any good.
So, bottom line: the middle of the window is a bit dead, but that Thursday the 20th afternoon is the standout. The Saturday morning the 15th is a good option if you just want clean small waves. The rest is a lot of wind and chop. Keep an eye on the forecasts, but for now, that’s the story.

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.
