Alright folks, Rusty here. Let's take a good long look at what’s coming up for E-Bay over the next couple of weeks. It’s not exactly firing on all cylinders right now, so we’ve got a bit of a slow start, but things do shape up nicely later on.

Right out of the gate, Monday the 13th through the first part of next week is pretty grim. We’ve got onshore winds, thunderstorms hanging around, and the wave energy is just weak to moderate – we’re looking at combined energy values in the low-to-mid hundreds (like 371 to 986). The swell is there, but the quality is poor to marginal at best. The water temp is about average for the time of year, nothing wild there. Honestly, the first few days are a write-off for a decent paddle.

Tuesday the 16th and Wednesday the 17th are much the same – light onshore breezes and poor surf quality. Don’t get your hopes up.

Now, here’s where it gets interesting. Sunday the 19th is your first real window. The wind swings offshore from the NNW in the morning, then light cross-off from the west in the arvo with only a slight air. The swell cleans right up – the data even says "clean". It’s small, around 2 ft to 3 ft from the SSW, with a solid 13-second period. For a reef like E-Bay, that’s long-period groundswell, which will wrap in nicely and hold its shape. The combined energy is still on the lower side (256 to 342), but with those winds, it’ll be glassy and fun for the advanced crew. Crowds are "sometimes" an issue here, so you might have the place to yourself if you’re lucky.

The next standout to circle is Monday the 20th. The swell bumps up to 5 ft from the south with a 16-17 second period – proper groundswell energy. The combined energy jumps into the strong range (1134). The wind is cross-on, though, from the ESE/SE at 6 mph, so it won’t be perfect, but the power is there. This is more of an expert wave given the size and the cross-shore bump, but if you’re skilled, it’ll be worth a look.

After that, we get a bit of a lull from Tuesday the 21st through Thursday the 23rd. The swell drops, the wind stays cross-on or onshore, and conditions turn marginal again. Not much to write home about.

But hold on – Friday the 24th starts a solid run of clean, glassy mornings. The wind goes glassy calm from the SSE on Friday arvo, and then Saturday the 25th and Sunday the 26th are both showing "glassy" conditions with barely a breath of wind (3 mph from the ESE or SSW). The swell is small, around 2 ft to 3 ft, and period drops to 14-18 seconds depending on the day, but the energy is moderate (up to 449). For a reef break, long-period swell with glassy conditions is a dream. This is the best stretch on offer – not huge, but incredibly clean. Even better, Monday the 27th morning shows "very good surf conditions" with 2 ft of 19-second SSW groundswell and glassy wind. That combined energy hits 520, which is moderate but with that period and wind, it’ll be silky smooth.

Finally, Tuesday the 28th wraps it up with 3 ft of S swell at 16 seconds and absolutely dead calm – zero wind. Another "very good" call from the data. That’s a quality, clean session to finish the outlook.

Overall, the first week is a bit of a bust, but the second half – from Sunday the 19th and especially Friday the 24th through Tuesday the 28th – holds some proper clean, lined-up reef waves. It’s not big, but it’s beautiful. Get on 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.
