The Lowdown
Alright folks, Rusty here with a look at what’s coming up.
Honestly, the next week or so is pretty quiet. We’ve got a bit of swell from the south, but the wind and conditions are just not playing ball. Monday the 20th sees a 5ft south groundswell with a long 17 second period, but we’ve got a light cross-onshore breeze messing with the surface. The combined energy is strong, sitting at 1177, so there’s juice there if you’re desperate, but it’s messy and the tide’s questionable, so not a standout. Monday afternoon is much the same story.
Tuesday the 21st through to Monday the 27th is a real struggle. The south swell stays small, mostly under 3ft, and onshore winds or cross-onshore chop ruin everything. The combined energy drops way down too – into the hundreds and even below 100 by the end of the week. Not worth paddling out, honestly.
Now, here’s the good news. Things turn around noticeably at the end of the month. Thursday the 30th of July, the wind goes glassy. We get a 2ft south groundswell, long period at 19 seconds, and a combined energy of 361, described as “expect good surf conditions,” with a score of 2. It’s small, but clean. Then Friday the 31st, the swell picks up a touch to 3ft from the SSW, period at 17 seconds, glassy as anything, and the combined energy jumps to 508. Very good surf conditions coming through. That stretch from Friday the 31st through to Monday the 3rd of August looks like the best on offer. Swell sizes hover around 3ft to 4ft from the SSW and S, periods still decent, winds staying offshore or glassy, and combined energy is solid in the 400-700 range, which is moderate to strong. The standout session would be Sunday morning the 2nd of August: 4ft SSW swell at 14 seconds, glassy, and the break gets the optimum west swell direction. That’s a nice clean reef setup, but you might have some company – crowds are marked as sometimes possible. This is an advanced reef break, and with the swell under 5ft, it’s fine for most experienced surfers, but beginners might find it tricky. With a period over 15 seconds in some of these, the wave shape should be good at a reef, and the long intervals will help with paddling out.
The first week of August holds similar promise. Monday the 3rd has a 3ft south swell at 12 seconds, offshore wind from the northwest, clean, combined energy in the 430s. A good solid option. Tuesday the 4th is also okay with 4ft south swell at 13 seconds and a light cross-offshore breeze.
So to sum it up: ignore the first week and a bit, it’s a write-off. The real window fires up from the morning of Thursday the 30th of July and runs through to Tuesday the 4th of August. Glassy conditions, clean lines, and building swell. A proper late July run that has me stoked.
Stay safe, check the tides, and I’ll see you in the water.

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.
