The Lowdown

Alright folks, Rusty here. Let’s get into it.

Right off the bat, I’ll be straight with you – the next couple of weeks don’t serve up a classic, but there’s a glimmer of hope if you’re patient. We’re looking at a long stretch of onshore winds and average conditions, but a few windows pop up for something decent.

The first real chance comes on Saturday the 15th, in the morning. E-Bay is a reef setup, and it’s fairly consistent, which is a bonus. The winds will be light offshore from the northwest – that’s a major positive, meaning the surface should be clean. Swell is coming from the south at 3 ft, with a solid 18-second period. That’s a proper groundswell. The energy is moderate (396), and while it’s not huge, the long period means it’ll have shape. For a reef, that’s a good thing. This is likely the best on offer, but it’s pretty small, so not a standout day for power.

That Saturday afternoon, the wind swings cross-on, and the swell bumps up to 5 ft, but with a shorter 14-second period. It’ll be more walled up with some wind ripples. Not the same quality.

The next interesting window is Tuesday the 18th. The morning sees a south-southwest swell at 5 ft with a 16-second period. The energy is strong (1301). However, the wind is onshore from the southeast at 9 mph. It’s going to be a bit messy. The afternoon gets worse, with the wind picking up to 12 mph onshore and the swell dropping to 4 ft, but the period is back up to 19 seconds, giving it a lot of energy (1815). Still, onshore wind and a reef can get bumpy. This is a “maybe” session if you’re desperate.

Into the second week, things get more hit-and-miss. Wednesday the 19th and Thursday the 20th have solid swell – 6 ft to 7 ft, with strong energy (2130 to 2465). But the wind is consistently onshore from the southeast. That’s a lot of power, but it’ll be lumpy. For a reef, that’s not the best combo. The swell is coming from the south-southwest, which is the optimum direction for E-Bay, so the break will handle it, but the onshore wind will chop it up. This is more for the die-hard crew.

The 21st and 22nd see the swell holding at 7 ft, but the wind stays onshore, and the period drops to 14-16 seconds. The energy is still high (2008-2164), but it’s going to be a messy, blown-out mess. Honestly, with that much wind and swell, this setup looks more interesting for kite surfing than paddle surfing.

From the 23rd into the 27th, the swell backs off and the onshore winds persist. It’s a gradual fade to small, choppy, and poor. The 24th of August has a brief moment with a 4 ft south swell and an 18-second period, giving it moderate energy (1435), but the wind is onshore from the southeast. It’s a tease.

The water temperature is about average for the time of year, so no surprises there.

Bottom line: The standout is Saturday morning, August 15th at E-Bay. It’s small, clean, and the offshore wind makes it the only truly glassy session. Everything else is a battle with the wind. The reef will hold its shape, but you’ll be wrestling with chop most days.

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.
