The Lowdown
Alright folks, let’s break down the next couple of weeks here at E-Bay. This is a reef setup, and we’re looking at a pretty slow start before things really fire up.
The early part of the outlook is a bit of a drag, honestly. We’ve got a few days of onshore and cross-onshore winds messing with the swell, and the water is sitting at a warm 85°F which is about average for this time of year. The combined energy is weak to moderate, but the conditions are just not making it worth paddling out. You’ll be battling wind and a bit of chop, so it’s a solid pass.
Heading into the first week of August, Tuesday the 4th is where we start to see a real shift. We get a clean 4ft S swell with a period of 16 seconds, and the wind goes glassy in the morning, then offshore in the afternoon. The energy is building nicely, and the surf is looking very good. This is a solid window for a session.
Then, from Wednesday the 5th through Friday the 7th, it gets proper good. The swell hangs around 5ft to 6ft from the S, with offshore winds. The energy jumps up to strong levels. It’s still manageable for advanced surfers, but the quality is excellent. Thursday the 6th and Friday the 7th are standouts, with glassy conditions and clean lines. The wait for this is worth it.
After a brief drop in quality on the 8th and 9th, the real fireworks come in the second week. On Thursday the 13th of August, we’re looking at a 6ft to 8ft S swell with a very long 22-second period. The energy is incredibly strong. This is big, powerful groundswell. For a reef break like E-Bay, that long period will draw up some serious, lined-up waves, but it’s strictly for experienced surfers only. The wind is light offshore, so it will be clean and hollow.
The standout of the entire outlook is Friday the 14th of August. We’ve got an 8ft S swell with a 17-second period, and a solid offshore wind from the NNW. The energy is massive. This is the kind of day that reef breaks were made for: big, powerful sets with clean faces. This is expert territory, no doubt. The crowd factor is listed as ‘sometimes’ so you might have some company, but the quality will be world-class.
So, to put it simply: the first few days are a washout. Don’t bother. The first real taste of good surf comes on Tuesday the 4th. The best on offer—and I mean the absolute best—is that massive swell arriving on Thursday the 13th and Friday the 14th of August. Get your board ready for that.

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.
