Updates in hr min s Forecast update imminent
Alright, surfers, Rusty here. Let's look at what we’ve got on the menu. We’ve only got one spot that’s even in the conversation for the next couple weeks, so all the focus is on E-Bay. It’s a reef setup, fairly consistent, and it seems to like a west swell direction. The water’s sitting at 86°F, which is about normal for this time of year, nothing crazy there.
The first real sniff of something good comes on Sunday morning, July 5th. We’re looking at a clean 3ft S swell sliding in, and the wind is dead glass. It’s going to be silky smooth out there. The energy is solid too, with a combined level of 518. That’s a moderate amount of grunt for that size, and with a 15 second period, you’re getting proper groundswell lines that will wrap around that reef nicely.
Then Sunday afternoon is the standout of the whole outlook. The swell bumps up a touch to 5ft from the S, still with that long 15-second pulse. The combined energy jumps all the way up to 1027, well into strong territory. That’s a lot of push for a 5ft wave. Wind stays glassy. This is excellent surf for experienced surfers – there’s some serious power in the water that afternoon. Just keep in mind it’s a bit big for the beginners.
After that high point, things get messy. From Monday through the rest of the week, the wind shifts onshore and we get a mix of cross and onshore winds with only knee to waist-high swell hanging around. It’s marginal at best, with energy dropping back into the low hundreds. Not worth paddling out for unless you’re really desperate.
There’s a bit of a lull, but then Thursday, July 16th shows some promise again. Both morning and afternoon have that glassy surface again, with a 3ft S swell and a very long 17-second period. The energy reading is back up to 374. It’s not big, but with that period, the wave shape will be clean and lined up on the reef. Just be aware that with a period that long at a beach break, it might break a bit too straight, but for a reef like E-Bay, it should be a treat.
After that, we get a few more days of glassy or near-glassy mornings with small 3ft to 3ft SSW swells, but the energy is fading into the weekend. By Sunday, July 19th, we’re out of puff with weak 2ft waves and poor wind.
The best bet: Get on E-Bay for Sunday, July 5th. The morning is clean, but the afternoon is where it’s at for the real power. The Thursday, July 16th window is a solid backup if you miss it, offering glassy conditions and long-period waves.
Stay stoked,
Rusty

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.
