The Lowdown

Alright, Rusty here. Let's get into it. Gotta be honest with you, the local scene is looking pretty grim for most of the next two weeks. We’ve got a long, slow run of messy, onshore stuff before a potential late-game corker shows up. It’s going to test your patience.

Looking at the whole picture, E-Bay is the only real game in town, and for the bulk of the forecast, it’s not much of a game. From September 7th right through until the 21st, we’re dealing with a persistent run of poor to marginal conditions. The wind is mostly from the SE through S, blowing straight onshore, and we’ve got a fair bit of storm activity around. The swell is hanging around the 3 ft to 5 ft range, mostly from the S and SSW, with combined wave energy mostly moderate or low (between 465 and 1757). It’s a long stretch of onshore wind chop and blown-out conditions with storm threats. There are a couple of days—the 11th afternoon and the 13th—where the wind eases to a cross or light cross-onshore, but the surf quality is still listed as marginal, so you’re not missing much. This is a solid ten-day gap where I wouldn’t bother waxing the board.

Now, the standout. Mark your calendars for Tuesday, September 22nd. This is the one. E-Bay wakes up. We’ve got a 7 ft swell pushing in from the S, with a period of 20 seconds. That is a very long period groundswell, and it’s bringing serious energy. The combined wave energy hits 4157, which is very strong. The wind swings around to a light ENE breeze at just 3 mph, coming cross-offshore. That’s a huge positive—it should keep the surface glassy and clean. Now, with a period that long at a reef break, expect those sets to stand up tall and powerful, with long gaps between them. This makes paddling out a bit easier, but once you’re in position, you’ll be looking at some proper, lined-up walls. This is excellent surf, but at 7 ft, it’s in that expert-only zone. If you’ve got the skills, this is a morning session that will be worth the wait. Crowds are listed as sometimes, and given the long wait for good waves, you can expect it to be a bit of a local gathering. Water temperature is about average for this time of year, nothing out of the ordinary to report.

So, the call is: a long, frustrating wait for one very promising but expert-only day. Stay optimistic, forecasts can change, but right now the 22nd is your target.

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.
