The Lowdown
G’day, this is Rusty. The next couple of weeks are looking pretty quiet for the most part, with just one real standout session that’s worth chasing. We’re starting off small and a bit thin, but there’s a pulse of solid groundswell coming through late next week that’ll get the heart pumping.
Right now, from Thursday 16th July through to Saturday 18th, we’ve got a clean little SSW swell running about 3ft, but the energy is weak (314 to 492). The wind’s light and variable, but the surf is just marginal. If you’re keen, Saturday morning is the best of this early stretch—glassy wind, 3ft SSW swell with a 14-second period (314). It’s small, but it’s clean. Water temp’s about average for this time of year.
Sunday 19th is a write-off—wind picks up cross-shore, the swell drops, and it’s messy. Things stay quiet through Monday 20th morning, but that’s where our big highlight sits. On Monday 20th July, the morning session at E-Bay (reef) is a beauty—5ft of S swell with a 17-second period, glassy offshore wind, and the combined energy hits 1179. That’s moderate to strong energy, and with that long period, the waves will be clean, punchy, and well-shaped. This is for experienced surfers—it’s not beginner territory. The break is fairly consistent, but crowds can happen, so get out early. The glassy wind is a major bonus.
Monday afternoon stays glassy with similar size, but the energy drops a little. Still very good.
From Tuesday 21st through Thursday 23rd, the wind turns cross-onshore, the swell fades, and the scores drop. By Friday 24th, it’s tiny and blown out—nothing to write home about.
There’s a gap of a few days of poor surf, but then a promising window opens late in the week. On Tuesday 28th July, the afternoon at E-Bay shows glassy conditions with a 3ft S swell and a 16-second period, combined energy of 533. It’s moderate energy, very clean, and the surf should be fun and well-shaped. That’s the next best option after Monday 20th.
Wednesday 29th July morning is also glassy, with 3ft S swell and a 15-second period (448)—clean and rideable.
Then on Friday 31st July, there’s a bigger pulse of SSW groundswell pushing 4ft with a very long 21-second period, and combined energy of 1410. That’s strong energy. The wind is light cross-onshore, so it’s not perfect, but it’s promising. Keep an eye on it—it’s a long-range call, so less certain, but if it holds, the reef will handle that long period beautifully.
Overall, the standout is Monday 20th July morning—glassy, solid 5ft S groundswell, long 17-second period, and strong energy. That’s the one to circle. Tuesday 28th afternoon is the next best, with glassy conditions and a clean 3ft S swell. The rest of the period is small or blown out, so pick your moments.
This is Rusty, signing off.

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.
