Table - best surf conditions forecast for E-Bay over the next 16 days.
Right then, let’s have a look at what’s on offer for E-Bay. To be real with you, the first week and a bit is a write-off. From Friday the 10th through to Saturday the 19th, it’s all onshore wind from the southeast and the swell is small and weak, never cracking 4 feet. The combined swell energy is mostly in the low to mid hundreds, topping out at 1070 on Tuesday the 14th, but with that constant onshore breeze it’s just messy. We’re looking at a solid 10-day gap of poor to marginal conditions.
Now, things start to get interesting around the 20th. Monday the 20th of July is the standout. The morning brings a clean 6-foot swell out of the south with a good 17-second period. The wind goes glassy, light from the east-southeast, so the surface will be like a mirror. The combined swell energy is a punchy 1810, which is a proper amount of power. This is a solid, expert-only wave at over 5 feet, so leave the foamies at home. E-Bay is an exposed reef setup, and with that long-period groundswell from the south, and the optimum direction being west, it’s going to wrap in nicely. That south swell with such a long period will barrel down the reef. It’s your best bet by a long shot. The water’s sitting at a warm 86°, which is pretty much bang on average for the time of year, so no surprises there.
The afternoon of the 20th is a step down with the same size but the wind swings onshore, so the morning is the window. After that, the swell fades quickly. The 21st drops to 4 feet with cross-onshore wind, and by the 22nd it’s all gone again. There’s a tiny blip on the 23rd with a glassy 2-foot wave, and another on the 25th with a glassy 2-foot south-southwest swell, but those are for a longboard on a flat day, nothing to get excited about.
So to sum it up: if you can only paddle out once, make it dawn on Monday the 20th of July at E-Bay. It’s the only real stand-out session in this whole 16-day window.

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.
