The Lowdown
G’day, Rusty here. We’ve got a bit of a mixed bag coming up at E-Bay over the next sixteen days, but if you’re patient, there are some real gems to be had. The water’s sitting at a warm 86°, which is about 1° above the norm for this time of year, so nothing too unusual, just your typical tropical bathwater.
The first real surf worth getting excited about kicks off on Wednesday, 15 July in the morning. The swell is a clean 4 ft from the south, with a long period of 15 seconds – that’s proper groundswell energy. The wind is dead glassy from the ESE, so it’s going to be silky smooth out there. The combined energy is moderate (968), so there’s enough push to make for some fun waves. This is a reef break, so that long period will wrap in nicely. Crowds are possible here, so don’t expect to have it to yourself. The afternoon holds similar, with a 4 ft south swell and glassy conditions, though the energy drops a bit to 681. This is the standout window of the first week.
Thursday, 16 July sees the swell back off to 3 ft, still from the south with a 15-second period, but the wind swings cross-on, so it’ll be a bit bumpy. Not the best, but still rideable if you’re keen.
Friday, 17 July is a write-off. The swell drops to 3 ft, wind is onshore, and the energy is weak (376). Leave the board in the car.
Saturday, 18 July offers a little hope. The morning is 3 ft from the SSW with a 14-second period and glassy winds. The energy is low (314), but it’ll be clean for a small wave session. The afternoon has a risk of thunderstorms, but still glassy, so you might get a window.
Sunday, 19 July has a morning offshore breeze from the NW at 15 km/h, with a 3 ft SSW swell (13 seconds). The energy is weak (229), but that offshore wind will make it look better than it is. The afternoon gets gusty with a cross-offshore wind, so not ideal.
Now, here’s the big one. Monday, 20 July brings a solid 5 ft south swell with a 17-second period. The combined energy is strong (1165), so there’s plenty of power. However, the wind is cross-on from the ESE, so it’ll be a bit choppy. This is a reef break, so that long period groundswell will produce some nice lines, but the wind is a letdown. If you’re an expert, it’s worth a look, but for the average punter, the conditions are marginal.
The rest of the week from Tuesday, 21 July through Thursday, 23 July is mostly poor, with dropping swell and onshore winds. The energy stays weak (under 500), and the swell drops to 1 ft by Thursday morning. Not worth paddling out.
We hit a dry spell from Friday, 24 July morning (1 ft, 20-second period, but weak energy at 172), though the afternoon of that day offers a little hope: a 2 ft south swell with a very long 18-second period and glassy winds. The energy is still low (268), but it’ll be clean. Then Saturday, 25 July morning is a real standout: 3 ft from the south, 16 seconds, glassy winds from the east, and the energy is moderate (550). This is your best bet of the second week. The morning is labelled as “very good,” and I’d agree – glassy, clean, and that long period will give some nice shaped waves at the reef. Crowds are likely.
Sunday, 26 July is similar, with 3 ft south swell and glassy conditions, but energy is lower (264). Still a fun morning session.
Monday, 27 July is a dud – onshore winds and a tiny 1 ft swell.
But then Tuesday, 28 July and Wednesday, 29 July come back strong. On Tuesday, 3 ft from the SSW with an 18-second period, glassy winds, and moderate energy (543). The afternoon is even better, with the same swell and glassy conditions. Wednesday sees 4 ft from the SSW, 16 seconds, and dead calm winds. The energy is moderate (610). These are the real standouts late in the period – clean, long period groundswell, perfect for a reef break. If you can wait, this is the best the forecast has to offer.
Overall, the best windows are Wednesday 15 July, Monday 20 July (for experts), Saturday 25 July, and Tuesday/Wednesday 28-29 July. The rest is mostly small or choppy. Get out there when it’s glassy.
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.
