The Lowdown
Alright crew, let's cut through it. This is a 16-day span for E-Bay, and it's a slow burner. You're looking at a solid week before anything is worth a second look. The first few days are a total bust – onshore winds and dodgy conditions, so don't bother.
The one to circle is the afternoon of Tuesday, September 8th. It goes glassy, just dead flat calm. You've got a 4ft SSW groundswell rolling in with a long 18-second interval. The energy is solid (979), so there's some real punch. That long period swell is going to hold up perfectly on the reef here. It's the best on offer. Keep in mind crowds are sometimes an issue, so expect some company for those clean lines.
There's a couple of other flashes later on. Sunday, September 13th is all glass in the morning and afternoon with a 3-4ft SSW swell (17-second period), and the energy is strong (952 and 886). Clean and long. Then, looking further out, Wednesday, September 16th shows glassy conditions again in the morning and afternoon with a 4-4ft SSW swell (15-second period) and solid energy (785 and 749). It's a nice way to wrap things up, but it's a long way off, so don't bank on it.
The rest of the fortnight is mostly cross-onshore chop and marginal surf. Water temp is a balmy 85°F, right about average for this time of year. T-shirts and boardshorts, mate.

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.
