The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Ekas-Inside over the next couple of weeks.
Alright, look, it’s gonna be a bit of a mixed bag. The bulk of the run is showing consistent swell, but it’s largely a crossing-off wind situation, which takes the shine off. The water temp is sitting right around 80°, which is bang on average for this time of year, so no need to dig out the 5/4. The standout period, if you can call it that, looks like the very end of the run, around the 11th and 12th of September, where we see some serious size on the table.
Things kick off this Saturday afternoon, the 29th of August, with a 6ft SW swell, but it’s a bit of a messy entry with those cross-off winds. The energy is moderate (1389). Sunday the 30th’s morning session drops a touch to 5ft SW, but the wind is still crossing off. We roll through the week into September with the swell bumping up to 7ft by Tuesday morning, but the wind just won’t give us a clean offshore. It’s all cross-off, all day, every day. The energy starts to climb though, hitting moderate to strong levels (2844).
The real heavy stuff starts to show up around the 8th of September. Tuesday afternoon the 8th sees a 7ft SSW swell with a very long 18 second period, and the energy is ramping up proper (4041). This is a groundswell, and it’s gonna be a big one. The 9th of September, Wednesday, is pushing 8ft SSW with the same long period, and energy is through the roof (4188). That’s expert territory, no doubt, and that long period will be macking at this reef.
The highlight of the whole forecast has to be the 11th and 12th of September. The 11th, Friday morning, is serving up a 8ft SW swell with a 19 second period. That’s a very long period groundswell, and the energy is at its peak for the whole run (4770). Then Friday afternoon jumps to 8ft SW with 18 seconds, another massive energy reading (4879). The wind is still cross-off, which is a real shame. Saturday the 12th keeps that 8ft SW swell going with solid energy. This is the best swell window, but it’s for experienced surfers only. The reef at Ekas handles that long period better than a beach break, so it’ll be holding shape, but the crowd could be a factor here as it’s a known spot.
After that, it starts to taper off a bit. The 13th of September, Sunday, is still a decent 6ft SW, but the energy is dropping back. Overall, the forecast is a bit frustrating with the constant cross-off wind, but the size and period in the second week are undeniable. Keep your eyes on that 11th and 12th if you’re a solid surfer.
Rusty.

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.
