The Lowdown
Alright crew, Rusty here, switching to good old imperial units. Let’s break down what’s coming for E-Bay. This is a reef break, fairly consistent, so you’ll have chances. Water temp is about 86°, which is a touch warmer than usual for this time of year.
The first few days, from Saturday the 25th through Monday the 27th, are a total dud. Swell is tiny, barely 2ft to 2ft, coming from the S and SSW with a decent period of 13 to 16 seconds, but it’s all onshore wind. The combined energy is weak (89 to 164), and the reports say poor surf conditions. Nothing doing.
Tuesday the 28th morning is still small with a cross-onshore wind, but Tuesday afternoon the wind drops to glassy. Swell is still only 2ft from the S at 15 seconds, energy a weak 128. It’s surfable but very ordinary.
Wednesday the 29th afternoon is where you start to see life. Glassy conditions, swell bumps to 2ft from the SSW, and the energy climbs to 293. The forecast says expect good surf conditions. It’s small but clean.
Thursday the 30th and Friday the 31st see the swell size moving up to 3ft–3ft, with a long period from the SSW (16–19 seconds). The energy is moderate (449 to 615). The winds are light and mostly cross-on or onshore, so it’s marginal with questionable tide conditions.
Saturday the 1st of August morning brings the first real bump: 4ft from the S, period 18 seconds, and the energy jumps to 1020 (moderate wave energy). The wind is light cross-onshore, but it’s still listed as marginal. This is the best of the first week, but the wind holds it back.
The real standout is Sunday the 2nd of August in the morning. Glassy conditions, 3ft of SSW swell at 16 seconds, and a moderate energy of 525. The forecast says expect very good surf conditions. It’s a clean, small-wave day with a long period, so it’ll be peeling nicely on the reef. Crowds are sometimes possible, so expect a few others.
Monday the 3rd of August morning is glassy again with 3ft of S swell at 15 seconds, energy of 452, and good surf conditions. A solid follow-up.
Now, the good stuff. Tuesday the 4th of August turns on the offshore wind. The morning brings a light offshore from the NNW with 3ft of S swell at 13 seconds. The afternoon sees a gentle offshore from the NW, same 3ft, period 12 seconds. Both are clean and labeled as good conditions.
Wednesday the 5th of August is even better. Light offshore in the morning with 3ft of SSW swell at 17 seconds, energy of 902, and very good surf conditions. The afternoon goes glassy with the same 3ft and 17-second period, energy 736. Very good again.
The absolute best on offer is Thursday the 6th of August. The swell pushes up to 5ft in the morning and 5ft in the afternoon, both from the S at 17–18 seconds. The energy is strong, hitting 1408 and 1444. The wind is a gentle offshore from the NNW. The forecast says excellent surf conditions for experienced surfers. This is a true standout. The swell direction is S, right in the sweet spot. At 5ft to 5ft, it’s expert territory, so only the skilled crew should paddle out.
Friday the 7th of August stays solid at 5ft–5ft from the S, but the wind swings to a moderate cross-off from the WNW, and the energy drops. Still marginal.
Saturday the 8th of August morning is glassy again with 4ft of S swell, period 14 seconds, and energy of 1308. Excellent surf conditions for experienced surfers. Another great session.
Sunday the 9th of August brings a bigger swell, 6ft–6ft from the S at 16 seconds, but the wind turns cross-onshore. The energy is strong (1474–1685), but the wind is a dealbreaker for clean conditions.
So, to sum it up: the first five days are a wash, then we get a few clean small days leading into the real gold from Tuesday the 4th through Saturday the 8th of August. The standout is Thursday the 6th of August with that strong, offshore, 5ft–5ft S swell. If you can only pick one session, that’s it.
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.
