The Lowdown

Alright, let me get my boardshorts on and look at this forecast for E-Bay.

Right off the bat, it’s a bit of a slow start. We’ve got a long period, 21-second groundswell rolling in on Monday the 13th, but it’s blowing onshore from the SSE at 9 mph, and the water temp is a balmy 86°, which is about average for this time of year. The conditions are just plain poor for a paddle session. The combined energy is moderate at 662, but the wind is just ruining it.

The pattern actually stays pretty marginal for a solid week. Tuesday through to the following Monday, we’re looking at waist-high waves at best, with the wind mostly onshore or cross-onshore from the SSE or ESE. It’s a real struggle to find a clean wave. The energy dips and rises, but the wind keeps it messy. For a few days there, it’s more of a kiteboarding setup than a surfable wave.

Now, the real story starts to turn around on Saturday the 18th. Saturday afternoon, the wind drops to a glassy 3 mph from the SSW. The swell is still small, around 3 ft from the SSW, but the glassy conditions are a massive positive. The energy is weak at 245, but it’s clean. This is the first sign of hope.

Then Sunday the 19th morning is a gem. Dead calm, glassy conditions, and still that 3 ft, 13-second SSW swell. It’s small, but it’s perfect for a longboard. The energy is still weak at 264. This is a standout for a relaxed, clean session.

After that, Monday the 20th brings a pulse of energy – the combined energy jumps to 1206 (strong wave energy) with a 5 ft S swell. But the wind is onshore from the SSE at 6 mph, and it’s a bit of a messy one. On Tuesday the 21st, the wind picks up to 9 mph from the ESE, making it choppy. Not the best.

The real winner for the whole forecast window is the final weekend. From Saturday the 25th through to Monday the 28th, we get a run of glassy conditions. The wind is light from the ESE, NE, and even calm at times. The swell is small, around 2 ft to 3 ft from the SSW, but the energy is weak to moderate. The standouts here are Saturday the 25th and Sunday the 26th, with glassy conditions and a clean 3 ft to 3 ft SSW swell. It’s not going to be a big day, but for a fun, clean surf on a reef break, it’s the best on offer. E-Bay is a fairly consistent reef break, but it can get crowded sometimes, so factor that in.

So, to sum it up for you: forget the first week, it’s a write-off. The best bet is the glassy, clean conditions on the weekend of the 25th and 26th. It’s a small swell window, but it’ll be a good one for a longboard or a mini-mal.

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.
