The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for the next couple of weeks.
The forecast opens with a bit of a flat, messy spell. We’ve got some swell on the cards but the wind and weather just aren’t playing ball for a while. It’s not until the 12th of September that we start to see a real change in the conditions, and that’s where the standout window begins.
The water temp is sitting at 85°F, which is about normal for this time of year.
E-Bay (reef) is our only real option on offer, but it’s a good one. The first week is a write-off, with onshore or cross-onshore winds and risk of thunderstorms every day, leaving the surf small and generally poor. The combined energy is weak to moderate, never really getting going.
Then, things start to look promising from Saturday the 12th. The morning is glassy with some clouds and only a slight breeze from the east, waves around 3ft from the SSW with a period of 14 seconds – clean, but small. The afternoon though, that’s the one to circle. Glassy conditions again, a 3ft SSW swell, but check this out: the period jumps to 19 seconds. That’s a very long period groundswell, and for a reef break like this, it’s going to produce some proper, lined-up waves. The combined energy is moderate (781), and it’s going to be clean as a whistle.
The run continues with small but clean conditions through the week, but the big standout is Monday the 14th of September. The afternoon brings a glassy sea, a solid 5ft S swell at 17 seconds. That’s excellent surf for experienced surfers. The combined wave energy is strong at 1374, and with that long period and glassy wind, E-Bay is going to be absolutely pumping. Just know that with consistent quality, crowds are sometimes a factor here.
The following days offer cleaner, smaller options with a couple more glassy windows on the 15th and 17th, but nothing that tops that Monday afternoon. Long range is looking promising, but keep your fingers crossed it holds.

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.
