The Lowdown
G’day, Rusty here. Let’s talk about what we’ve got for Ekas-Inside.
The outlook is a bit of a mixed bag. The wind’s always coming from that SE to SSE direction, hanging in the cross-off zone, so the waves are never going to be glassy. The good news is there’s plenty of swell, but it’s constantly fighting that breeze, making most sessions feel a bit marginal. The water temp is about 80°, which is dead normal for this time of year.
If you’re looking for the one true standout, circle Monday, August 17th on your calendar. That morning, the swell is a clean 5ft from the SSW with a solid 14-second period. The wind is only a gentle 9 mph from the SE, and the combined energy sits at 1106, which is moderate but very workable. The notes say “expect very good surf conditions,” so that’s your session. It’s a fairly consistent reef, so it’ll be running, and crowds are only “sometimes” a problem. The swell is right in the optimum direction (SSW), and that reef will handle those long-period lines nicely for a beginner-friendly wave.
After that morning, it’s a long stretch of “almost but not quite.” From the 17th afternoon right through to the 28th, the wind just won’t lay down. The biggest push comes on Thursday, August 20th—a solid 10ft SSW groundswell with a 16-second period, and the energy is pumping at 4117. But with a 12 mph cross-off wind, it’s going to be messy. At that size, it’s strictly for experts, and the long period means it’ll be powerful.
There’s one more potential window on Friday, August 28th. The morning shows a 8ft SSW swell from the SW with a 17-second period, a gentle 9 mph breeze, and moderate energy of 3216. It’s a good looking combo, but it’s ten days out, so treat it as a promising possibility rather than a sure thing.
So, the call is simple: Monday the 17th morning is your best shot. After that, keep an eye on the 28th, but don’t book your time off just yet.
Rusty.

Information about the Ekas-Inside Surf forecast

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.
