The Lowdown
G’day, Rusty here. We’ve got a solid run of swell ahead at Ekas-Outside, but it’s not without its quirks. The pattern locks in from Sunday, 30 August, and keeps rolling through to mid-September. There’s no gap at the start – we’re straight into it. The water’s sitting at 80° with an anomaly of 0.0, so that’s pretty much spot on for this time of year – nothing out of the ordinary there.
Sunday the 30th starts us off with a clean 5 ft SSW swell, period at 13 seconds, and a light ESE cross-off breeze. Combined energy’s at 968 (moderate). It’s a beginner-friendly size, and the winds are kind – that’s a nice way to ease into the week. The swell holds steady through Monday morning at 4 ft but the period jumps to 18 seconds, which is a proper groundswell – lots of energy in the water (1440), but that long period can make it a bit straight at a reef like this, so watch for it. Wind’s still cross-off from the SE.
By Tuesday, 1 September, the swell picks up to 7 ft with the same long period, and the energy’s climbing into the four-digit range (2849). It’s starting to get a bit more punchy, but still manageable. Winds stay cross-off, though the speed’s up to 19 mph by the afternoon – that’s a fresh breeze. Wednesday’s similar, with 7 ft swell and moderate energy (2580), but the wind swings to SSE at 22 mph by the arvo, which is getting a bit hectic.
The first standout really shapes up around Thursday, 10 September. Morning brings a 7 ft SSW swell, 16 seconds, and a gentle 9 mph SE breeze – that’s cross-off and glassy. The combined energy’s at 2087 (strong), and the conditions are clean enough for experienced surfers. It’s not huge, but the quality’s there. The optimum swell direction is SSW, and that’s exactly what we’ve got, so the reef should be lining up nicely.
Then we get a proper flex on Friday, 11 September. Morning swell hits 7 ft from the SW, period 19 seconds – that’s a very long-period groundswell. Energy’s pumping at 4801 (very strong). Winds are cross-off from the SE, 16 mph. By the afternoon, it’s 10 ft with 18 seconds and energy at 5093 – that’s pushing into expert territory. This is the biggest, most powerful swell of the window, but it’s also a bit raw. The reef should handle it, but it’s not for the faint-hearted.
Saturday, 12 September, stays big at 8 ft SW, 17 seconds, with cross-off winds and energy at 4018. Still a heavy session for the experienced crew. The run continues into the second week – Sunday, 13 September, has 7 ft, and Monday, 14 September, sees another 10 ft pulse with 17 seconds and energy at 4589. That Monday morning’s a ripper, but again, it’s big and demanding.
Through the whole period, the wind is persistently cross-off from the SE or SSE, which keeps the surface clean despite the size. The only slight hiccup is Wednesday, 9 September, where the wind goes cross-shore with a bit of chop. That’s the one to maybe skip. Crowds at Ekas-Outside are listed as “sometimes,” so expect a few others out, but it’s not a zoo.
The real standout is Thursday, 10 September morning – that’s your best balance of clean conditions, solid 7 ft swell, and that beautiful 16-second groundswell lining up with the optimum SSW direction. The crowd factor’s manageable, and it’s a reef, so the long period works in your favour. If you’re after raw power, Friday, 11 September and Monday, 14 September are the heavy hitters, but they’re only for the skilled.
Rusty.

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.
