The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for this spot.
We’ve got a solid, persistent run of SW groundswell lining up for the next couple of weeks. The water’s sitting at a warm 79° with a tiny anomaly of -0.5°, so right around average for this time of year. The wind is locked in from the SE, which is cross-off here and keeps things clean, but it’s not that beloved offshore. Still, it’s not onshore rubbish.
The standout session in the first week is going to be the Saturday morning, September 12th. We’ve got a clean 5ft SW swell running at 14 seconds, combined energy of 1896, and a gentle 9 mph SE breeze. That’s a really nice, manageable size with enough period to shape up nicely. It's pushing into the fairly consistent range, and it’s beginner-friendly at this size. There’ll be a few others out – crowds rated as "sometimes" so expect a crew but nothing crazy.
Further along, keep an eye on Sunday, September 20th, especially the afternoon. The swell bumps back up to 7ft from the SW with a 16-second period, combined energy hitting 2146. Still clean with that moderate SE cross-off. The size is getting up there, but it’s not too gnarly for most intermediates.
Then, and this is a long-range promise, the week of the 22nd looks tasty. Tuesday morning, September 22nd sees the swell jumping to 7ft from the SSW, with a 17-second period and energy roaring up to 3476. That’s a powerful, long-period groundswell. Perfect for a reef like this, but it’s going to be a handful; over 8ft on the afternoon session, so that’s expert territory only. The wind stays cross-off, so it’ll be clean, but this is for the big dogs. There’s a real promising window from the 22nd morning through the 24th, with strong energy readings consistently over 2000.
The last couple of days of the window show another pulse. Friday, September 25th is a sleeper: only 5ft, but a huge 21-second period and combined energy of 2994. That’s a very long-period groundswell. It’ll be fat and lined up perfectly on this reef, but the size is manageable. Then the 26th morning cranks up again with 8ft at 18 seconds, energy at 3799 – another strong, expert-level day.
Overall, the best bet for a clean, fun, all-day session is that Saturday morning on the 12th. If you’ve got the experience, the 22nd morning through the 24th is a solid run of chunky, powerful surf. Just remember, that distant stuff on the 25th and 26th is promising but less certain.
Stay stoked.

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. If you surf the same spot (Ekas-Outside) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
