Alright, Rusty here, let’s talk about E-Bay over the next couple of weeks.
Right away, there’s surf to be had, no waiting. The pattern is clean mornings with a few afternoons getting a bit lumpy, but the quality is there if you pick your window.
Friday morning July 3rd is a nice gentle start. Clean conditions, light cross-offshore breeze. Swell is from the south at 3ft, with a long 15-second period (404 combined energy). Water temp is a warm 86°, about average for this time of year. The real standout, though, is Saturday afternoon the 4th. That’s the best early on. Swell drops a little to 2ft from the south, but the period stretches out to 18 seconds, giving it real push and shape. The wind goes glassy, the energy jumps to 639, and conditions are very good. Circle that one.
Sunday morning the 5th is also looking excellent with glassy conditions, 3ft south swell and a 15-second period (518 energy). The wind is dead calm, so it’ll be clean and consistent. Monday and Tuesday mornings the 6th and 7th are smaller, around 2ft from the south-southwest with a 16-second period, but the wind is glassy each morning, making for tidy, user-friendly waves. Energy drops to the 300s, so it’s a bit weaker, but still fun on a reef.
Wednesday morning the 8th is a highlight – 4ft south-southwest swell, 15-second period and glassy wind, energy at 809. Very good conditions. But Wednesday afternoon goes onshore. Thursday morning the 9th is glassy again with a similar 4ft south swell (642 energy), worth a paddle.
From the 10th to the 13th, things get weak and messy. Wind turns onshore or cross-onshore most of the time, and the swell drops under 3ft with shorter periods. A few days are borderline poor, energy dropping into the 100s. There’s a bump on the 14th with bigger 16-second period south swell and energy in the 400-600 range, but the wind is onshore or cross-onshore all day, so not a pure clean option.
The back half, from the 15th to the 18th, settles into a nicer rhythm. Mornings and afternoons are glassy or clean cross-offshore. Swells sit around 2ft to 3ft from the south-southwest, with periods mostly 14-16 seconds and energy in the 300-500 range. The best of this late run is Thursday afternoon the 16th – 3ft south-southwest swell with a 16-second period, clean cross-offshore wind, and energy at 557. Very good conditions again. That’s your other standout, along with Saturday afternoon the 4th.
Overall, E-Bay is a solid reef break that's fairly consistent, and with the right winds – which we get plenty of – the waves will be clean and fun. It can get a crowd sometimes, so if you want a quiet peak, paddle out early on the glassy mornings.
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.
