The Lowdown
Alright, gather round. Rusty here, looking at the only game in town for the next two weeks.
We've got a long stretch of consistent, solid swell on the way, but it's not all clean sailing. The setup is all about Ekas-Inside, a sheltered reef break that's going to be handling a lot of energy. The water temp is sitting at 79°F, which is pretty much normal for this time of year, so no surprises there.
The first week is a bit of a mixed bag. We're looking at a solid run of 7ft to 8ft SSW groundswell with a very long period of 16 to 17 seconds from Friday the 21st through Sunday the 23rd. That's a lot of water moving – the combined energy is pushing 3445 (moderate to strong) on Friday afternoon. The issue is the wind. It's a consistent cross-off from the SE and SSE at 15 to 16 mph. While it's offshore, it's a bit of a breeze, keeping the surface textured. It's clean, but not glassy. With that size and period, it's too much for beginners, and the long period will make the sets a bit lazy at a reef break, but there'll be some good ones. The crowd situation is "sometimes", so you might have a few others out.
The middle of the week, Monday the 24th through Wednesday the 27th, sees the swell ease a touch, dropping to 5ft to 6ft, but the wind stays similar. The energy backs off a bit, with values around 1000 to 1700. It's still clean, but it's a bit of a grind with that constant moderate breeze.
Now, the real standout. The best bet is the morning of Tuesday, the 1st of September. The swell holds at a solid 6ft from the SW, with a 17-second period, and the wind drops right away to a gentle 9 mph cross-off from the SE. The combined energy jumps to 2578. That's the window. The conditions are described as "excellent surf conditions for experienced surfers". That's the one. It's a couple of weeks out, so keep an eye on it, but it's the pick of the bunch.
Then on Wednesday the 2nd, we get another pulse of 8ft SW swell, with the wind again easing to 9 mph in the afternoon. That afternoon session is also flagged as excellent for experienced surfers and has a big energy reading of 3163. That's a close second.
After that, the swell slowly fades into the first week of September, with smaller waves and a return to the breezier conditions.
So, if you're looking for the absolute best, mark your calendar for the morning of September 1st. The 2nd of September afternoon is also a cracker. The rest of the period is mostly about solid, clean but choppy waves for the experienced crew.
Rusty, signing off.

Information about the Ekas-Inside Surf forecast
The above surf forecast table for Ekas-Inside provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ekas-Inside can be found by selecting the local surf guide option on the grey menu. Our Ekas-Inside 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 (Ekas-Inside) 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 Ekas-Inside 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.
