The Lowdown

Alright, crew, Rusty here. Let’s look at the stretch ahead for E-Bay. It’s a bit of a mixed bag, so let’s break it down.

We start off pretty flat. Friday morning there's barely a pulse with 1 ft of weak, long-period swell and the energy reading is a paltry 91 – that’s weak. The water is sitting at 85°, which is about normal for this time of year, but the surf just isn't there. Friday afternoon is a bit more organised with a moderate energy of 141, but it's still small and bumpy.

The first real glimmer of hope comes on Saturday morning. It's still small at around 3 ft, but look at that – glassy conditions with not a breath of wind. The swell is from the S with a period of 18 seconds. That's a proper groundswell, but at this size, it’s more about the clean lines than any power. The energy jumps to a moderate 408. It’s not going to be world-class, but it's a start. Saturday afternoon is workable, but a light cross-on breeze kicks up a little texture.

Sunday is where things start to get interesting. The morning shows 4 ft of S swell with a 15-second period, and it’s glassy again. The combined energy is 950 – that's moderate but building. This is the first real window to get some fun ones. The wind is off, and the swell is there. It’s not huge, but the quality looks right. Sunday afternoon backs off a touch but stays glassy.

Then we hit a bit of a slump. Monday and Tuesday are blown out with onshore winds and poor conditions. Tuesday afternoon has more energy in the water – 1831, which is moderate – but it's messy. We have to wait for Wednesday for the size to come up, but it's still onshore and lumpy. Wednesday morning is 7 ft from the SSW, but the cross/onshore wind is going to make it a battle. This is getting into the size that might be a bit much for the beginners, but the conditions are poor.

The main push comes through the middle of next week. From Wednesday afternoon into Thursday, the swell peaks. Wednesday afternoon has 7 ft of S swell with an energy of 3004 – that's strong. Thursday morning holds 7 ft with energy at 2139. But all of this is accompanied by stiff onshore winds. It's going to be big, grindy, and tough to surf. This is more for the experienced heads who don't mind the battle. For anyone else, it might look more like a kite-surfing day than a paddle-surfing day, with that wind and size.

After that, the swell backs down but never fully cleans up. The rest of the week and into the next is a story of onshore winds and junky conditions. There are a few windows, like the 27th morning, where the wind drops to glassy (energy at 679), but the swell is down to 4 ft. It could be worth a dawn patrol if you're keen.

The standout, though, is clearly the early part of the period – Sunday, August 16th is your best bet. The morning glass and 4 ft of S swell at 15 seconds will give you clean, lined-up waves at this reef break. It's not huge, but it'll be the most fun you'll have, especially with the lighter crowds likely. The other one to keep an eye on is the 27th of August, but that's a long way out, so treat that as promising, not certain.

Until next time, 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.
