The Lowdown

Alright folks, Rusty here. Let’s have a honest look at what’s on the table for the next couple of weeks. It’s a tricky stretch, so I’ll keep it real with you.

Right off the bat, it’s going to be a waiting game. The first decent chance we see is for Wednesday the 19th of August, but to be frank, it’s not looking like a classic. The swell is there, coming in at a solid 7ft from the SSW, and there’s a ton of energy in the water, but the wind is messing with us – a light cross-onshore from the south is putting a bit of texture on the face. It’s a similar story through the rest of the week and into the next. There’s consistent swell, but the wind just won’t get out of the way, staying cross-on or onshore, and the guidance keeps calling it marginal. The water is a warm 85°, which is pretty average for this time of year, so at least you won’t need a steamer.

The only real standout in this whole 16-day window is for E-Bay. This is an advanced reef break, and when it’s on, it’s a proper wave. The best window looks like the very end of the run, around Monday the 31st of August into Tuesday the 1st of September. We've got a solid 5ft to 6ft of SSW groundswell rolling in, with a very long period of 19 seconds. The energy numbers jump way up, which tells you there's some serious grunt behind these sets. The wind is predicted to be light and from the south-southeast, which puts it offshore for this break. That is the major positive. Expect long, waiting sets with heaps of push, but that long period can make it a bit straight at a beachie – here at this reef, it should groom up nicely. Keep in mind, this is a spot for experienced surfers only; over 5ft with that power, it’s no place for beginners, and the crowds can be a factor here. We’re a week and a half out, so the detail might shift, but this is the one window that has the best chance of being truly good. Before that, from the 19th to the 30th, it’s a stretch of average-to-poor conditions. The swell drops right off after the 30th, getting down to 1ft to 3ft by the 3rd of September with dropping energy, and the wind stays a problem. A few of those days with the onshore wind and that beach-break setup could actually be more interesting for the kite crew than for us on paddles. All in all, hang tight for that last week of August and keep an eye on the 31st.

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.
