The Lowdown
Alright folks, Rusty here. Let’s break this one down. We’ve got a solid run of swell coming for Ekas-Outside, but the wind is gonna keep you honest, so you gotta pick your windows.
Right from Thursday the 13th, we’re into it. There’s a solid 8ft of SSW groundswell in the water, and this is a long-period swell at 17 seconds – that’s proper deep-water energy pushing in. Water temp is sitting right at 80°F, which is dead average for this time of year. The wind is a steady cross-off breeze from the SE. Not glassy, but it’s clean, and that’s a big win for this reef. The combined swell energy is pumping at 3123 (moderate to strong energy), so there’s plenty of push. Just know that with this size (over 5ft and pushing 8ft), it’s not a beginner’s wave anymore.
Friday the 14th, the swell eases a touch to 7ft in the morning, still from the SSW and still a very long 16-second period. Wind stays cross-off and the surf stays clean – solid option again. Energy is still moderate-strong (2669). Saturday the 15th gives us another 7ft to 8ft day with that same long-period groundswell, and the wind actually backs off to a gentle 9 mph cross-off in the morning – about as tidy as this stretch gets.
Now for the standout: Wednesday the 19th and Thursday the 20th are your money days. Wednesday morning we see the swell bump to 8ft from the SW with an 18-second period – that’s very long-period groundswell with insane energy (3648). Wind is a light 9 mph cross-off, and by the afternoon the swell hits 8ft with the same 18-second period and the energy hits 4127 (strong). Thursday morning then pushes it to a solid 10ft from the SW. That’s expert-only territory – over 8ft, only the crew with some experience should be out. Energy is massive (4003). Wind stays cross-off, so it’ll be clean and lined up.
A word on that long period: at Ekas-Outside, a reef break, this is a good thing. Long-period SSW and SW swells wrap in nice and hold their shape – they won’t break too straight like at a beach break. The sets will be bigger and more spaced out, giving you time to paddle back out.
From Sunday the 16th through Tuesday the 18th, the swell drops to 5ft to 6ft but stays rideable and clean with the cross-off wind. Not pumping, but fun.
The second week gets a bit windier. Friday the 21st sees the wind pick up to 22 mph in the afternoon – still 7ft of swell, but choppy. Saturday the 22nd has a similar issue with 19 mph winds. The bright spot later on might be Monday the 24th – the swell is a smaller 6ft, but the wind drops to a light 9 mph cross-off in the morning, making for a much cleaner, user-friendly day. By Wednesday the 26th, we see another bump to 7ft with a 17-second period in the afternoon, but the wind hits 19 mph again, so it’s a trade-off.
To sum it up: Wednesday the 19th and Thursday the 20th are your best bets for the biggest, most powerful groundswell with good winds. If you want a slightly smaller but still solid window with lighter winds, Saturday the 15th morning is a standout.
Stay safe out there.

Information about the Ekas-Outside Surf forecast
The above surf forecast table for Ekas-Outside provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ekas-Outside can be found by selecting the local surf guide option on the grey menu. Our Ekas-Outside 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-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.
