The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cooking at Ekas-Inside.
The water’s a warm 79°, which is pretty average for the season, so no shocks there. The whole run is dominated by a solid, long-period SSW groundswell and those steady cross-off southeasterly winds. It’s not going to be picture-perfect, but there are a few sessions worth paddling out for.
The first surfable window is Saturday, August 22nd afternoon. The swell is a solid 7ft from the SW, with a very long 16-second period. That’s proper groundswell, and the combined energy is a hefty 2288 (moderate wave energy). The wind is a steady 12 mph from the SE, blowing cross-off, so the surface will be clean. The main hitch is the tide – it’s marginal, so you’ll need to work the banks. With the swell over 5ft, it’s a bit more than a beginner’s wave.
Sunday morning brings similar conditions: 7ft from the SSW at 15 seconds, cross-off SE wind, but that tide issue is still there. The energy is 1971. Sunday afternoon the wind picks up to 16 mph, the swell drops to 6ft, but the energy jumps to 2635. Still, that tide factor holds it back.
The best bet in the first week is Wednesday, August 26th morning. The swell drops to 6ft, but the period is still a nice 14 seconds from the SSW. The wind eases to a light 9 mph from the SE, and the forecast actually says “expect very good surf conditions.” The energy is moderate at 1114, and with that light cross-off breeze, it’ll be glassy and clean. Thursday, August 27th morning is also a good shout – the swell is only 4ft, but the period is 16 seconds from the SW, winds are light at 9 mph, and the energy is 1207. It’s smaller, but it’ll be tidy.
Now, watch out for Friday, August 28th morning. The swell jumps to a massive 10ft from the SSW at 17 seconds. The combined energy is a very strong 4539. The wind is only 9 mph from the SSE, cross-off, so it’ll be clean. But you’d better be an expert – over 8ft is only for the brave. The 17-second period is very long, so at this reef, it’ll be powerful and lined up, but you’ll be waiting for the sets. The afternoon drops to 8ft with 3685 energy.
The swell hangs around into the first week of September. Tuesday, September 1st morning has 7ft from the SW at 17 seconds, with a strong 3023 energy. The wind is a moderate 16 mph from the SE, still cross-off. Wednesday, September 2nd morning offers 8ft from the SW, 17 seconds, and 3067 energy, with lighter wind at 12 mph. Both are for the experienced crew.
After the 4th of September, the energy drops off a cliff, and the swell gets smaller and shorter-period, so it loses its appeal.
The standout sessions are Wednesday, August 26th morning for the clean, user-friendly waves, and Friday, August 28th morning for the big, powerful groundswell if you’ve got the skills. The rest is a bit of a grind.
Rusty.

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.

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.
