The Lowdown
Alright, let's get into this one. The next stretch is a bit of a mixed bag, but there are some proper windows if you play it smart. The first few days are your best bet, with clean conditions and a solid push of groundswell. It gets a bit messy mid-week, but there might be a worthwhile return right at the end. Keep an eye on that.
We’re starting off on Wednesday the 5th here at E-Bay. It’s a reef break, exposed to the west, and it’s picking up a SSW swell at 3.6ft with a long 15-second period. That’s proper groundswell energy, and the combined energy is at 1079, which is a solid, moderate push. The wind is light and offshore from the NNW, so it’s going to be clean, rippable lines. The water’s sitting at 85.1°F, which is pretty much bang on average for this time of year. There might be a rumble of a storm around, but don’t let that put you off. This is a good one for experienced surfers—the reef can be a bit unforgiving, but the waves will have some proper shape to them. Crowds are sometimes a thing here, so you might have to share it.
Thursday the 6th, the swell bumps up a touch to 5.2ft, still from the south, with a period of 17 seconds in the morning, easing slightly to 16 in the arvo. The energy is dialling up too, hitting 1491 and 1508. The wind is still offshore, swinging from N to NNW, so it remains clean and glassy. This is another solid day for the experienced crew. The long period means the sets will have some punch, but the reef will sort them out into nice lines.
Friday the 7th is the pick of the first run. The swell builds to 5.9ft in the morning and 6.2ft in the afternoon, straight out of the south with a period of 18 seconds. The energy is kicking hard now, with readings of 2201 and 2280 – that’s strong, powerful surf. The wind is light and offshore, from the N, making it an absolute gem. This is the standout of the early week. It’s a proper groundswell, but at this size and with that period, it’s going to be a handful. It’s for advanced surfers only – 6.2ft is getting up there in size. The consistency is fairly good, so you’ll be busy.
Saturday the 8th is still well worth it. The swell holds at 5.9ft in the morning and 5.6ft in the afternoon, still from the south with a 16-second period. The kicker is the wind – it goes glassy in the afternoon with a light easterly breeze. That’s about as good as it gets for conditions. The energy is still strong at 1688 and 1441. Another day for the more experienced surfer, but the clean conditions will make it a joy.
Right, now we hit a bit of a lull. Sunday the 9th, the wind swings around to the southeast, becoming cross-onshore, and things start to get a bit choppy. The swell drops slightly to 5.6ft and then 5.2ft, but that cross-on breeze will chop up the surface. It’s not a write-off, but it’s not the clean, groomed conditions we’ve had.
Monday the 10th, the wind goes fully onshore from the SSE, and the swell period jumps to 20 seconds, but the quality is questionable. The energy is still strong, hitting 2380 and 2767, but with the onshore wind, it’s going to be messy. Not one to get too excited about.
Tuesday the 11th sees the biggest swell of the period, with 7.5ft in the morning and 6.9ft in the afternoon, from the south with an 18-second period. That’s a lot of water moving, and the energy is cranking at

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.
