The Lowdown
Alright, surfers, Rusty here. Let’s get into it.
Look, the first week or so is going to be a real grind. We've got a long stretch of marginal to poor conditions, with the wind mostly onshore from the south-east or south-south-east. It’s going to be a waiting game.
The one spot to keep an eye on, our only real hope in this forecast, is E-Bay. This is a reef break that’s fairly consistent, and it works best when the swell is coming from the west.
Through to the end of the week, we are looking at a lot of messy conditions. The swell hangs around 4.3ft to 2.9ft from the SSW, but that onshore wind is just ruining it. Combined swell energy is moderate, reading between 411 and 974. It’s just not worth paddling out for.
Now, there is a real bright spot on Saturday the 19th. Get up early. The morning is looking magic with a glassy wind from the west at only 3 mph. The swell is 2.9ft from the SSW with a very long 18-second period. This is a proper groundswell. Combined energy is moderate at 636. That long period will make for some beautiful, lined-up waves at the reef, but it also means the sets will be few and far between. Paddling out should be a breeze, though. The afternoon gets a bit lumpy with a cross-onshore wind, so make sure you get on it in the morning. Expect some company though – crowds are sometimes an issue here.
Things go back to being ordinary for a solid week after that, with onshore winds and poor conditions. The swell stays small, around 3.3ft to 1.6ft.
Hold on, because there's a second chance. On Wednesday the 23rd in the afternoon, we get another glassy window. The wind will be light from the west-southwest, giving us glassy conditions. The swell is 3.9ft from the south with a 16-second period. The combined swell energy hits a strong 1055. This one is for the experienced surfers only, as the forecast says excellent conditions but for those who know what they’re doing.
Looking further out, around Sunday the 27th and Monday the 28th, the swell is set to pick up significantly. We're looking at 4.3ft to 6.6ft from the south, with a very long period of 20 to 21 seconds. The combined energy is going to be massive, hitting 1832 to 2868. But, the wind is onshore or cross-onshore, so the quality will be questionable. If you’re an expert and don't mind a bit of chop, there could be some powerful, thumping waves. The 6.6ft swell is only for experts.
So, the standouts are clear: Saturday morning the 19th for the glassy, clean conditions, and Wednesday afternoon the 23rd for the solid, powerful swell with a glassy surface. The late-month swell is a big "maybe" due to the wind.

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.
