Alright, Rusty here. Let’s break it down.
We start off strong Tuesday morning, July 7, at E-Bay – a reef break, exposed to the swell. Water temp is about 86°, just a touch above normal for this time of year. It’s glassy, with a 3ft SSW groundswell and a long 16-second period. The wave energy is moderate (341), and with no wind, those waves will be clean and peeling. This is the best session of the whole forecast – a real gem. The swell direction hits the optimum (W), and for an advanced wave, you can’t ask for more. Crowds are possible, so get out early.
The rest of the first week goes downhill. Tuesday afternoon gets a light onshore S breeze at 3 mph, and from Wednesday through the weekend, it’s cross-onshore or onshore, with most conditions marginal. Swell runs 4ft to 5ft from the S and SSW, periods dropping to 14-15 seconds, but the wind chop ruins it. Friday morning is outright poor. Saturday offers a brief break, but still nothing to write home about.
Sunday morning, July 12, turns glassy again – a 3ft S swell (12 sec) with light airs, decent energy (238), and good conditions. Small but clean.
The second week is mostly cross-onshore light breezes, with swell between 3ft and 4ft from the S and SSW, periods from 12 to 18 seconds. Not much happening. But Wednesday morning, July 15, is glassy again: a 3ft SSW swell (16 sec), moderate energy (538), and the call is *very good*. That’s another standout, but it’s over a week away, so keep an eye on it.
From July 16 to 19, it’s onshore wind and risk of t-storms, with swell staying 3ft to 4ft – mostly marginal.
Monday afternoon, July 20, goes glassy with a 3ft S swell (13 sec) and moderate energy (338) – a clean option.
And finally, Tuesday morning, July 21, is the last real standout: glassy, a 4ft S swell (12 sec), strong energy (582), and *very good* conditions forecast. That’s two weeks out, but if it comes together, it’ll be the best of the late run.
So, your best bets are this Tuesday morning (July 7) and Wednesday July 15, with Tuesday July 21 as a hopeful closer. The rest is mostly average, but there are enough glassy windows to keep you interested if you’re selective.
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.
