The Lowdown
Alright, let me start. We got just one spot to talk about: E-Bay. It’s a reef break, open to the swell, and it likes the swell from the west, but we’re getting a lot of south and south-southwest swell. That’s not ideal, and the first week and a half is mostly a dud.
The forecast kicks off Wednesday, July 22, with a small 3ft southerly swell, but the wind is onshore from the southeast at 12 mph. It’s messy with weak energy reading 286 – not worth the drive. Thursday and Friday are even smaller, down to 1ft, with onshore wind again. Hard pass.
Saturday the 25th and Sunday the 26th stay tiny – around 2ft. On Sunday afternoon, the wind goes glass with a light west-southwest breeze at 0 mph. That’s clean, but the swell is barely 2ft from the south with a 14-second period. Combined energy is only 103 – a glorified lake. You might get a knee-high ride on a longboard, but nothing to write home about.
Then there’s a long dry spell. From Monday the 27th through Friday the 31st, the swell stays puny – 1ft to 3ft – and the wind is mostly cross-onshore or onshore. The energy does climb to 630 on the 30th, but the wind kills it. Poor conditions all around.
There’s a tiny window on Saturday, August 1: the swell comes up to 3ft from the south-southwest, period 16 seconds. By afternoon the wind goes glass with a light southerly at 3 mph, and the energy hits 375. Conditions are “good” – clean, but small – for a quiet late-day session.
Now, here’s where it gets real. Sunday, August 2: the swell pushes to a clean 4ft from the south, period 16 seconds, and in the morning we get a light offshore from the north-northwest at only 6 mph. Combined energy jumps to 1074 – that’s strong. This is excellent for experienced surfers. This is your first true standout: clean lines, solid power, offshores. Mark your calendar.
Monday the 3rd holds at 3ft from the south, period 14 seconds, with light cross-offshore or glassy winds. Energy drops a little, but it’s still clean – a good follow-up day.
Then Tuesday, August 4, is the big one. Swell builds to 6ft from the south, period 18 seconds. That’s long-period groundswell with serious punch – combined energy hits a massive 3322. Morning wind is light cross-offshore from the northeast, so it’s clean. This is for experts only – at over 6ft on a reef, it’ll be heavy. Afternoon goes glassy but still 7ft – a beautiful but challenging day.
Wednesday the 5th and Thursday the 6th keep the run going: 5ft to 5ft from the south, long periods of 16-18 seconds, with light cross-offshore winds. Energy stays high (1098 to 2253). Perfect for strong surfers on a good reef.
Water temp is about normal for the season – nothing weird there.
Overall, the first week is flat and wind-affected, but the second week turns on. The standout days are Sunday, August 2 through Tuesday, August 4. Tuesday is the crown jewel for experts – big, clean, powerful. It’s a long-range call, so keep an eye on the charts, but this one looks worthy.

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.
