The Lowdown

Alright crew, Rusty here, talking about E-Bay.

This is a reef break that’s pretty consistent and open to the swell, but the first week is a real grind. The water is warm at 85°F, which is a bit above average for this time of year, so that’s a nice little perk. But the surf? It’s rough. We’ve got a solid, long-period groundswell from the S, with periods around 16-17 seconds, giving us moderate wave energy. But the wind is on it from the SSE, and it’s just messy. You’re looking at poor conditions for days. The swell is around 3ft, but it’s not clean, and it’s not surfable. This stretch from the 6th through the 10th is a total washout – the wind is onshore every session, and the ratings are rock bottom.

There’s a little hope on the morning of the 12th, but it’s still marginal with a cross-onshore breeze. The swell picks up a bit, and the energy is building, but it’s not until the 14th that we see something. Monday morning the 14th is interesting – the wind goes light and onshore, almost glassy, and we’ve got 4ft of SSW swell with a 16-second period. The energy is moderate, and it’s a marginal call, but it’s the first real sign of life.

Now, here’s the one to watch. Wednesday the 16th. That’s your window. The morning and afternoon are both glassy – wind from the ENE and then WSW, barely a breath of air. The swell is a consistent 4ft to 4ft from the SSW, with a 15-second period, giving moderate energy. The conditions are described as “expect very good surf conditions,” and that’s the truth. For a reef break like E-Bay, glassy, clean conditions with a solid groundswell is as good as it gets. This break is for advanced surfers, so if you’re not up for a reef, stay home, but for those who are, Wednesday the 16th is the one.

The Thursday the 17th afternoon also looks clean with a gentle offshore from the NNW and 4ft of SSW swell, so that’s a solid backup. But Wednesday is the real deal.

After that, the swell jumps to 5ft by the 19th, but the wind turns back onshore, and the quality drops. It gets too big for beginners and will be a choppy mess. The long period groundswell (15-16 seconds) is still there, but with the onshore wind, those waves will be lumpy and hard to handle.

So here’s the word: the first week is a dud. Wait for Wednesday the 16th. That’s your best shot. The 17th is a decent fallback. After that, it’s a toss-up with size and wind.

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.
