The Lowdown

Alright, surfers, let's get into it. This is Rusty, and I'm looking at a long-range forecast for E-Bay.

First off, the water temp at E-Bay is sitting at 85°, with a tiny anomaly of 0.9°, so it's pretty much bang on average for this time of year.

We've got a few windows of surf across the next 16 days, but don't go planning your week around it. The real action kicks off on Tuesday, August 25th, with a small but promising SSW groundswell coming in at 4 ft, a period of 15 seconds, and a combined wave energy of 683 (moderate). The wind is a light onshore breeze from the SE, so it's a bit of a battle. The conditions are described as marginal, so it's a session for the dedicated.

The standout of the whole period is Wednesday, August 26th. Early morning we’ve got glassy conditions with the wind swinging light ESE, and the swell is 3 ft from the SSW with a 13-second period, giving us a combined energy of 327 (moderate). It's not a big swell, but with that glassy surface, the wave quality should be pure. The afternoon holds the same, with light SW winds. This is your best chance for a clean, fun session.

Things get real interesting on Thursday, August 27th. The swell jumps to 5 ft from the SSW, with a long 18-second period and a combined energy of 1570 (strong). That's serious energy. But the wind is onshore from the SSE, and there are thunderstorms about. It's a bit of a beast, likely too powerful for beginners at that size. This is expert territory.

We then hit a bit of a lull from Friday, August 28th, through the weekend. The swell drops back to 3 ft or less, and the wind is generally messy. The end of the first week and into the second week sees a lot of "marginal" and "poor" conditions, with mostly onshore winds and some stormy weather. There's a gap of several days where it's not really worth paddling out.

Looking farther out, around Tuesday, September 1st, we see a pulse of 5 ft SSW swell (energy 1068 - strong), but the wind is cross-onshore, so it'll be choppy. The later part of the second week, around September 8th and 9th, shows a building swell again, with a solid 5 ft from the SSW and a long 18-second period, but again, the wind is a problem. The forecast confidence for these late dates is lower, so it's a "watch and wait" situation.

For the standout, it's got to be Wednesday, August 26th. The swell is small (3 ft), but the glassy conditions and clean SSW swell direction make it the pick of the bunch. It's a true, clean, and fun morning session. For the big wave hunters, the Thursday the 27th and the swells around September 9th are the ones to watch, but they'll need the wind to cooperate.

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.
