The Lowdown
G’day, Rusty here. We’ve got a solid run of surf on the cards at Ekas-Outside – a reef setup that’s fairly exposed to the swell and pretty consistent through the whole 16-day window. The water’s sitting at 80°, which is about average for this time of year, so nothing unusual there.
The pattern kicks off with a nice pulse of long-period groundswell. On Wednesday 2nd September morning, we’re looking at a 7ft SW swell with a period of 17 seconds – that’s a proper groundswell with heaps of energy (combined energy of 2469). The wind’s a steady 25 km/h from the SE, blowing cross-offshore, so it’s clean. That long period means the waves will be well-shaped and punchy, but at a beach break it might bend a bit too straight – on this reef, it should line up nicely. It’s a beginner-friendly break, but with 7ft on offer, it’s more for the intermediate crowd. The afternoon picks up a similar 7ft swell, still clean.
The swell settles a touch through Thursday and Friday, staying around the 5ft to 5ft mark with 14-16 second periods, and the wind holds cross-off. Not massive, but clean. Come Saturday 5th September, the swell starts building again – 6ft SSW on the morning, jumping to 6ft with a 16-second period in the afternoon (combined energy 1766). Still clean.
Sunday 6th September has the best early-morning call: 7ft SSW, 14 seconds, and the wind drops to 20 km/h cross-off. That’s a standout session – clean lines, moderate energy (2201), and the reef handling it well. The afternoon stays clean with 5ft.
Tuesday 8th September is the big one. The afternoon jumps to a 10ft SSW swell with an 18-second period. That’s a huge groundswell, strong energy (4821), and it’s heading straight for the optimum SSW direction. The wind swings to a cross-shore 20 km/h from the S, which will put a bit of a cross-chop on the surface. This is expert territory – over 8ft and powerful. If you’re not solid, sit this one out.
The rest of the first week and into the second week stays consistent: 7ft to 8ft SSW swells, 14-19 second periods, and cross-off winds. By Sunday 13th September morning, we see another 10ft SSW pulse with an 18-second period (combined energy 5654) – that’s very strong energy. Wind is 25 km/h cross-off, so it’s clean again. Another standout for the big-wave crew. The afternoon holds 10ft with a 17-second period, though the wind picks up to 30 km/h fresh breeze, still cross-off.
Through the second week, the swell stays in the 6ft to 8ft range, with the wind never getting nasty. The standout there is Wednesday 16th September morning – 8ft SSW, 16 seconds, 25 km/h cross-off, clean (energy 3590). Thursday 17th holds 8ft SSW with 20 km/h cross-off, also clean.
Overall, the best on offer is Tuesday 8th September afternoon (10ft, 18 seconds, cross-shore wind) for experts, and Sunday 13th September morning (10ft, 18 seconds, clean) for the same crew. For the intermediate surfer, Sunday 6th September morning and Wednesday 9th September morning (8ft, 16 seconds, clean) are top picks. The break is fairly consistent but doesn’t have a crowd tag in the guidance – it says crowds are “sometimes,” so you might find a few others out, but nothing crazy.
Watch the tide: the forecasts all note “marginal surf forecast or questionable tide conditions,” so check your local tide chart. This reef can get shallow at low, and the big swells will be pushing hard.

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.
