Table - best surf conditions forecast for E-Bay over the next 16 days.
Alright, let me break this down for you. E-Bay is looking like a slow starter, but there’s a couple of real gems if you’re patient.
From Sunday the 12th through Saturday the 18th, it’s pretty grim. Onshore wind, small sloppy surf. The swell energy is weak, mostly in the 200 to 400 range, with periods that aren’t doing anything special. Not worth getting wet.
Then Sunday the 19th morning brings a change. Glassy conditions, 2ft of S swell with a 21-second period – that’s long-period groundswell. The combined energy is 504, so there’s some real punch. The glassy surface will make it look like a treat. This long-period energy will work well on this reef, giving you clean lines, though expect longer waits between sets. Afternoon holds 3ft, still glassy, with energy hitting 940. Water temp is about normal for this time of year.
That window shuts fast. Monday the 20th sees 6ft of S swell, but onshore wind and a period dropping to 17 seconds makes it messy. Energy spikes to 1738, but with the wind on it, this reef break will be a mess. Skip it.
Then another quiet spell until the standout. Saturday the 25th morning: 4ft of S swell, 16-second period, combined energy at a massive 2080. The wind is glassy. This is expert territory – the reef will handle that long-period energy and give you powerful, lined-up waves. Crowds are possible, so get in early. Afternoon stays glassy, same size, energy drops to 888, but still solid.
Sunday the 26th is tiny and messy. Monday the 27th morning offers a small, glassy 3ft S swell with a 14-second period and 345 energy – clean but small.
The clear winner is Saturday the 25th morning. Glassy, powerful S swell, perfect for the reef. That’s your session.

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.
