The Lowdown

Alright, surfers, Rusty here. Let’s have a look at the ocean for the next couple of weeks.

Right off the bat, it’s a bit of a slow start. We’ve got a lot of onshore wind and stormy weather to deal with, so the first real window of opportunity isn't until the weekend. The forecast is built around just one reef break, E-Bay, a fairly consistent advanced spot that loves a west swell. The water temp is sitting about average for this time of year, so nothing shocking there.

Tuesday, September 8th through to Friday, September 11th is a write-off. Onshore winds, thunderstorms, and poor surf conditions. The combined energy is weak to moderate, but the wind is just ruining everything. Don't even bother paddling out.

Saturday, September 12th is where it gets interesting. The morning is still a bit average with a cross-shore breeze and a 3 ft swell from the SSW. But keep your eye on the afternoon. The wind is due to go glassy, the swell is bumping up to 4 ft from the SSW, and the combined energy jumps to a strong 1393. The period is a very long 19 seconds, which is proper groundswell. This is a tricky one for a reef, but that glassy surface and solid energy might just make for some memorable waves. It’s the standout of the whole outlook, but it’s for the experienced crew.

Sunday, September 13th through to Wednesday, September 16th is back to the same old story. Onshore winds, risk of thunderstorms, and poor or marginal conditions. The swell hangs around 4 ft to 5 ft, but the wind is trash. The energy is moderate to strong, but completely unfriendly.

Thursday, September 17th is a real treat. The morning cleans up with a light cross-offshore breeze from the NNE on a 5 ft SSW swell. The afternoon is even better: offshore wind from the NW, 4 ft SSW swell, and clean conditions. The period is a solid 15 seconds. This is your second standout window. It’s not massive, but it’s clean and powerful.

Friday, September 18th keeps the good vibes rolling. Glassy conditions in the morning with a 3 ft SSW swell, and then a moderate offshore breeze in the afternoon with the same size. Clean waves are on the cards.

Saturday, September 19th onwards into the second week, the surf is still there but the quality drops. The swell stays around 3 ft to 5 ft from the SSW, but the wind turns cross-onshore again. The combined energy waves between moderate and strong, but that light cross-onshore breeze will keep things a little bumpy. It’s marginal, but there’s still energy in the water. The long period (21 seconds) on Tuesday, September 22nd, is notable, but likely too straight for this setup.

Overall, the best windows are the glassy Saturday afternoon on the 12th, and the clean offshore days on the 17th and 18th. Don't expect much before that.

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.
