Alright, Rusty here, let's talk about what's coming up for E-Bay.

Overall, we're looking at a bit of a slow burner. The first few days are pretty average, with a lot of marginal conditions and questionable tides holding things back. The real highlight, and the one I'd be circling, is that brief window around the weekend of the 19th and 20th of July when things finally clean up. It's not a massive swell, but the conditions should be spot on.

Let's break it down. The week starts off with some energy in the water on Tuesday the 7th – a nice long-period groundswell from the SSW at 16 seconds pushing through. The morning glass-off is perfect; it’s dead calm with a small 3 ft set rolling in (combined energy of 341). The water's sitting at a warm 86°F, which is about average for this time of year. The afternoon sees a light onshore breeze come up, making it less clean, so get on it early.

Through Wednesday the 8th and Thursday the 9th, the swell builds a bit, hitting around 4 ft to 5 ft from the S, with a solid period of 15 seconds. The energy gets up there (combined energy of 747 and 941). But the wind is never quite right – it's cross or cross-onshore, leaving a bit of a bump on the surface. It's surfable, but you'll be working for it.

Friday the 10th and Saturday the 11th drop off a little. We're looking at 3 ft to 4 ft, period dropping from 16 to 13 seconds, and the wind stays onshore. The energy fades and the quality goes with it. Saturday is a write-off – poor conditions.

There's a bit of a flat spell through Sunday the 12th and into the week of the 13th, with small, weak swells and cross-onshore winds. The energy dips below 200 on the 12th. A few waves, but nothing to get excited about.

Here's where it gets interesting. On Friday the 18th of July, a much bigger pulse of swell hits – pumping up to 6 ft from the S with a 17-second period. The combined energy jumps to 2118, which is proper strong. But the wind is cross-onshore and gusty, so the surface will be choppy. The afternoon drops to 5 ft with lighter wind – still not perfect, but it's there.

Then, the standout window arrives. Sunday the 19th and Monday the 20th of July are the days. The swell settles back to a clean 3 ft to 4 ft from the S, with a 14-second period. But the wind goes glassy, dead calm. Combined energy is a moderate 723 and 515, so there's enough push for a fun, clean wave. This is the one to aim for. E-Bay is a reef break, and with that long-period S swell and an optimum direction from the West, it should line up nicely. Crowds can be possible here occasionally, so don't be surprised if a few others have the same idea.

Tuesday the 21st hangs on with clean, glassy 4 ft surf in the morning before dropping away to almost nothing in the afternoon. After that, the 22nd gets very small again.

So, bottom line: Don't stress about the first week. The real action is waiting for you on the 19th and 20th. That's your call.

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.
