The Lowdown
Alright, Rusty here again, talking in feet and miles per hour for the imperial crew.
So, Ekas-Outside is looking at a solid run of swell, with water temps running about average for this time of year. The swell direction is SSW, which is the sweet spot for this reef. The combined energy is strong to very strong, often over 3000 and even pushing past 4000, so there’s plenty of power.
From Thursday the 13th through the end of August, it’s a bit of a tease. Swell is mostly 5ft to 8ft, with a very long period groundswell – 14 to 18 seconds – that’s real energy. The wind is a moderate to fresh cross-off out of the SE and SSE, keeping the waves reasonably clean but never turning glassy. The wave comment flags marginal surf or questionable tide conditions for nearly every session, so the quality is holding back.
The real standout is the morning of Monday the 24th of August. Swell eases to about 5ft from the SSW, period stretches to 19 seconds – that’s a long-period groundswell – and the wind drops to a gentle breeze from the ESE at just 9 mph. That’s the lightest wind of the whole stretch. The wave comment calls it “excellent surf conditions for experienced surfers.” The combined energy is still 2689, so there’s plenty of push. For a reef, that long period and lighter wind could produce beautifully shaped, clean waves with easy paddling between sets. That’s the session to aim for.
On other days, the swell stays solid, mostly 5ft to 8ft, but hitting 10ft on the morning of Thursday the 20th of August. That’s expert territory, especially with 16-second period and wind picking up to 19 mph in the afternoon. For beginners, anything over 5ft is getting spicy, and a lot of this run is over that. Better sit it out.
Crowds are a real factor at Ekas-Outside – it’s popular when it’s working, and with this much consistent swell, expect company.
No gaps in the surf – it’s on every day. But most of it is held back by that cross-off wind and questionable tides. The 24th is the one that could really shine.
Rusty.

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-Outside 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.
