The Lowdown
Alright, this is Rusty, checkin' in with the outlook for Ekas-Outside. We've got a decent run of swell on the way, but it's one of those forecasts where you’ve gotta pick your moments.
Right off the bat, we’re looking at a solid, long-period SW groundswell that’s already rolling in. The water temp is about what you'd expect for this time of year, so no nasty surprises there. This is a fairly exposed reef break, and it likes swell from the SSW, so it's in the ballpark.
The first week is a bit of a mixed bag. Starting Sunday the 13th, we’ve got 6ft to 7ft of SW swell with a very long 18-second period. The energy is pumping—moderate to strong (2707). The issue is the wind. It's a moderate breeze from the SE, which is cross-off. It’s clean, so the waves will have shape, but it’s not glassy perfection. The model keeps flagging some tide issues, so you’re not going to get perfect, peelers every set. This pattern of clean but not epic continues through the week, with the swell slowly dropping and the period shortening a bit. The energy stays moderate to strong (in the 1000-2000 range) but the wind stays on that cross-off, which is okay but not the best.
The standout in this first week is Sunday the 20th of September. The morning brings a nice 7ft SW swell with a 16-second period. The energy is right up there (2023). It’s still cross-off wind, but lighter, making it much better than the previous days. The description says “excellent surf conditions for experienced surfers,” which it will be. With that size and period on a reef, it’s not a beginner’s wave, but for anyone with a bit of nerve, it’s a sweet spot.
We then get a bit of a lull around Monday the 22nd, with the swell dropping to 5ft-5ft. But don't go anywhere.
The absolute best on offer is at the end of the run. Sunday the 27th of September is the session to circle on your calendar. We’ve got a 7ft SW swell with a 15-second period and the energy is strong (2120). But the magic is in the wind: it’s an offshore ESE at just 10 km/h (6 mph). That’s a light breeze and offshore. This is going to be clean, lined-up, and firing. “Excellent surf conditions for experienced surfers” is the word. The morning looks like the pick, but the afternoon is nearly as good. Monday the 28th also looks excellent with that wind staying light, but the 27th is the true stand-out.
Earlier in the second week, on Wednesday the 23rd and Thursday the 24th, the swell is back up a bit (7ft - 8ft) but the wind is a fresh cross-off breeze (20-30 km/h / 12-19 mph). It’ll be chunky and messy, better for a big board or maybe a kite session at a beach break, rather than a clean paddle session at this reef.
In summary, Ekas-Outside is going to be on and off. The most reliable, high-quality windows are Sunday morning the 20th and then especially Sunday the 27th and Monday the 28th of September.
Stay stoked,
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. 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.
