The Lowdown

Right, Rusty here again. Let’s break down what’s coming in proper terms.

The first few days are small and tricky. A few clean windows, but you’ll need to time it right around the afternoon storm risks.

Saturday morning the 18th at E-Bay is worth a look. The swell is only 3ft from the SSW with a long 14-second period. Wind is glassy from the NNW. Combined energy sits at 314, so moderate. It’s not a huge day, but it’s a clean one.

Sunday morning the 19th still offers 3ft of SSW swell, but the wind is picking up from the west, keeping it cross-off. Still surfable and clean enough. The energy drops a tad to 285. By the afternoon, the wind goes cross-shore from the SW, and you can just about call it a day.

From Sunday afternoon right through until next week, there’s a long gap. Most days have onshore winds or very small, weak swell. Days like Tuesday and Wednesday are a write-off.

Now for the real highlights. Lock in Monday the 20th. E-Bay switches on with 5ft of S swell, and a long 17 to 19-second period. The combined energy is strong at 1184. Early morning wind is offshore from the NNW, turning glassy by afternoon. Clean, powerful, and for experienced surfers only. The beginners will find it too much.

Skip ahead to Thursday the 30th. The afternoon goes glassy with 3ft of SSW swell at 20 seconds. Energy is 656 – moderate. Small, but clean and long. A good log day.

Then Friday the 31st is the best day of the whole outlook. E-Bay sees 5ft of SSW swell, again with an 18-second period. Energy is very strong at 1327. Clear skies, glassy wind. This is the one to aim for. Excellent conditions for experienced surfers, with proper power and clean faces.

As we roll into August, Saturday the 1st is still good in the morning with 4ft swell and glassy conditions. Sunday the 2nd has the wind dropping to absolutely calm, with 4ft of groundswell. Glassy perfection.

So, call it now: Monday the 20th and Friday the 31st are your best bets. The 31st especially is a cracker.

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.
