The Lowdown
Right off the bat, I gotta be straight with you. The next week and a half is looking pretty grim for E-Bay. We’ve got some solid south swell energy rolling in, but it’s being hammered by onshore winds and thundery conditions. The water’s sitting at a warm 85°, which is pretty much average for this time of year, so no surprises there.
The first real glimmer of hope doesn’t come until Monday, the 31st of August. That morning, the wind dies right off, going glassy. The swell is a clean 4ft from the SSW with a long 17-second period, and the combined energy picks up to 679 (moderate). It’s still a bit of a wait, but that morning session is the standout. The afternoon stays glassy with a 4ft SSW swell and 18-second period, energy jumps to 936 (moderate). It’s not huge, but it’ll be clean.
Then Tuesday, the 1st of September, is the real peak. The morning brings a 5ft SSW groundswell with an 18-second period, and the combined energy hits 1393 (strong). The wind is glassy. This is an advanced-level wave, and E-Bay is a reef break, so it’s for experienced surfers only. The afternoon sees the wind shift onshore, but that morning window is the best the whole outlook has to offer. Crowds are possible here, so get in early.
After that, we see a slow fade. Wednesday the 2nd still has a clean 4ft SSW swell with glassy conditions in the morning, but the energy drops to 914 (moderate). Then it’s a long, slow slide into marginal and poor conditions for the rest of the outlook. The swell drops, the energy fades, and the wind stays onshore. By the time we hit the 5th and 6th of September, it’s all small, weak, and messy.
So, to sum it up: the wait is real. The first recommendation isn’t until the 31st of August. The only true standout is the morning of Tuesday, the 1st of September. Get on it, because the rest of the run is a write-off.

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.
