The Lowdown
Righto, Rusty here. Let’s have a look at what’s cookin’ for E-Bay over the next couple of weeks.
Alright, we’ve got a pretty slow start, but hang tight. The first real surf worth paddling out for kicks off on Sunday, the 2nd of August. The water temp is sitting at a warm 85°, which is about average for this time of year, so no surprises there.
Sunday morning (2nd August) is a bit touch-and-go with some cross-onshore breeze making it a little shaky, but the swell is a clean 3 ft from the south with a super long period of 19 seconds. That’s proper groundswell energy, and with a combined energy of 812 (moderate), it’s got some push. The real gem is Sunday afternoon, though. The wind swings to the west and goes glassy – dead flat calm – and the swell bumps up to 4 ft from the south, period 18 seconds, energy 821. That’s an absolute treat for a reef break like E-Bay. The water will be like a mirror, and those long-period lines will wrap in nicely. This is the standout of the early run.
Moving into Monday (3rd August) and Tuesday (4th August), the swell holds around 4 ft to 4 ft from the south, with periods still in the 14-16 second range. The wind is offshore or glassy for most of those sessions, especially Tuesday morning and afternoon with a glassy NNE and ESE breeze. The combined energy climbs into the 800s, so the waves have some grunt. This is clean, consistent surfing for anyone who can handle a reef.
Wednesday (5th August) is still good, but the wind picks up a bit – a cross-offshore breeze from the north, 15-20 km/h (9-12 mph), keeping the face clean. The swell dips slightly to 4-4 ft, but the energy is still high at 817 (Wednesday morning) and even jumps to a strong 1051 (Wednesday afternoon). That’s moderate wave energy but with a nice push.
Now, Thursday (6th August) things get a bit more serious. The swell jumps to 5 ft from the south, period 17 seconds, and the combined energy hits 1478 and 1564 – that’s strong wave energy. But the wind is howling from the north at 30-40 km/h (19-25 mph), making it a strong offshore. That means clean faces but a real battle to get out. This is for experienced paddlers only.
The real highlight of the whole forecast comes in on Friday, the 7th of August. The swell hits 6 ft – 7 ft from the south, with a perfect 18-second period, and the combined energy is massive at 2794 and 2781. That’s very strong wave energy. The wind is a moderate offshore from the NW, 20 km/h (12 mph), keeping it clean. This is expert territory – the waves are big, powerful, and long-period. Not for the faint of heart, but if you’ve got the skill, this is the best session of the window. Saturday (8th August) and Sunday (9th August) hold similar size with 6 ft to 6 ft, still offshore and glassy, with energy in the 1500-1800 range. Still excellent for experienced surfers.
Then, from Monday (10th August) onwards, the wheels fall off a bit. The wind shifts onshore from the SE, and the swell gets messy. Monday and Tuesday (10th-11th August) have some size – 4 ft to 7 ft – but with onshore winds, it’s choppy and poor. The energy is still high (1264 to 3099), but the quality is gone. By Wednesday (12th August) it drops to a tiny 1 ft, and the rest of the week through to Sunday (16th August) is a mix of small, weak swells (1 ft to 5 ft) with onshore winds and poor conditions. The energy is low to moderate at best, and the wind is onshore the whole time. Not worth a paddle.
Bottom line: The window is Sunday the 2nd through to Sunday the 9th of August. The absolute standout is Friday the 7th – big, clean, powerful south swell at E-Bay. Sunday afternoon (2nd) and the Monday/Tuesday sessions are also top-notch for cleaner, smaller waves. After that, it’s a write-off for a good week. If you don’t get on it in the first week, you’re waiting a long time.
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.
