The Lowdown
G’day, Rusty here with the imperial outlook. It’s been a flat start but there’s a big pulse comin’ through the long-range that’s got me keen. First week is near dead, but things turn right at the start of August.
Right now, E-Bay (a reef setup) is offering next to nothing. Friday the 24th to Sunday the 27th of July is flat or tiny—0.7ft to 2ft, mostly from the south, with onshore wind and weak energy (49 to 164). Water temp is 86°, which is 2° warmer than normal—kinda notable, but you won’t feel it if you’re dry. Conditions poor, no point paddling out.
Monday the 28th and Tuesday the 29th of July: a slight bump to 2ft–2ft, still south, but we get a few glassy windows. Energy climbs a little (121–158), still weak. Scores a 1 out of 10, surfable if you’re desperate but really ordinary.
From Wednesday the 30th of July through Saturday the 1st of August: swell picks to 3ft–4ft, south-southwest, period lengthening to 17–19 seconds. That’s proper groundswell. Energy jumps to 410–924, but wind is light cross-onshore, conditions still marginal. Not clean, but you can see the system waking up.
Sunday the 2nd of August morning: glass-off with 3ft of SSW groundswell at 16 seconds, energy 758, and “expect very good surf conditions.” That’s the first real standout window. Small but clean.
Monday the 3rd of August morning is the pick of that week. Swell to 5ft SSW, 17 seconds, energy 1156, glassy. “Excellent surf conditions for experienced surfers”—a 4/10 day, and for this spot that’s gold. Swell direction from SSW matches E-Bay’s love for west swell. Clean lines, good power. Crowds can be a factor, but Monday morning might be quiet.
Tuesday the 4th and Wednesday the 5th of August hold at 4–4ft, with clean cross-offshore and light offshore winds from the north and northwest. “Expect very good surf conditions,” scores 3/10. Fun if you can get out.
Thursday the 6th of August morning: 5ft S swell, 18 seconds, energy 1705, clean cross-offshore. “Excellent surf conditions for experienced surfers,” score 4/10. Afternoon bumps to 6ft S, 17 seconds, energy 2656. Getting bigger and better.
Absolute standout is Friday the 7th of August. Morning: 10ft S swell, 20-second period, offshore wind from the north, energy 6543—massive. “Exceptional surf conditions for expert surfers,” score 7/10. Afternoon holds at 10ft S, 19 seconds, cross-offshore wind, energy 5906, score 6/10. This is a long-period groundswell—shaped up, powerful, perfect for a reef. Only for experts; at 10ft it’s too big for beginners. Crowds will be there, but if you’ve got the skills, this is the morning to aim for.
Saturday the 8th of August backs off to 8ft S, 17–18 seconds, energy still strong at 4398, but wind turns cross-onshore from the southeast, conditions drop to marginal.
In short: first week is a bust. Second week, from Sunday the 2nd through Friday the 7th of August, you’ve got a run of building, clean surf. Highlight is Friday the 7th of August morning—10ft, offshore, exceptional. Circle that one. 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.
