The Lowdown

Alright, Rusty here. Let's have a look at what E-Bay has coming our way.

This reef setup is exposed to the swell and is fairly consistent, but don't get too excited just yet. We're looking at a bit of a flat spell to kick things off, with nothing worthwhile until later in the first week. The water temp here is sitting at a warm 85°F, which is just about average for this time of year, so nothing weird going on there.

Things finally start to tick on Sunday, the 16th of August. Sunday morning is where you want to be paddling out. We've got a 4ft S groundswell rolling in with a 15-second period – that's proper, long-period energy. The wind is a light NE breeze at 3 mph, coming cross-offshore, which is going to keep things nice and clean. The combined swell energy is sitting at 562, which is moderate. This is the standout session of the whole run, with very good surf on the cards. Sunday afternoon stays clean with glassy conditions on a 3ft S swell, but the morning has the better size and energy.

Monday the 17th through to Saturday the 23rd of August is a rough stretch. The swell bumps up, hitting 7ft on the 19th and 20th, with a very long 18-second period from the SSW. The energy numbers are huge – we're talking 2417 and 2796 for those sessions, strong to very strong. But the wind is mostly onshore or cross-onshore, and the surf quality is described as marginal at best. That 7ft to 7ft range is getting into expert-only territory due to the size, and with the wind chopping it up, it’s a write-off for a good paddle session. Honestly, with that much power and onshore wind, this setup looks more interesting for kite surfing than paddle surfing during that whole week.

After that long, poor stretch, we finally get some relief. On Thursday the 27th of August, we have another true standout. Both the morning and afternoon sessions are looking excellent. We've got a 4ft SSW groundswell with a 16 to 17-second period. The wind goes glassy – absolutely dead, at 3 mph – so you’re looking at perfect, clean conditions. The combined energy is moderate, around 742-767. This is your second best window, and it's worth waiting for.

The last few days drift back into marginal conditions, though Sunday the 30th of August has a little bump in size to 6ft from the SSW, but the wind is onshore again, so it’s more of a grovel than anything special.

So, bottom line: if you can get out Sunday the 16th in the morning, that's the pick. Otherwise, hold out for the glassy conditions on Thursday the 27th. The middle of the window is a bust for clean waves.

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.
