The Lowdown
G'day, Rusty here. Let's look at what's on the cards. We've got a stretch of surf coming, but it’s gonna take a while to really fire. The main player is Ekas-Outside, a reef setup that’s fairly consistent. There’s a lot of southwest swell in the water, but the wind is mostly cross-off or cross. It’s gonna be a slow burn.
First up, Thursday the 3rd of September through to Friday the 4th we have some small, clean surf. Swell is around 5 ft to 5 ft from the SW, with a long 14 to 16 second period. But the wave energy is moderate at best (1277 down to 843), and the forecast calls it marginal. The moderate breeze from the SE keeps it clean, but the quality just isn't there yet.
Then from Saturday the 5th, things start to pick up. Swell bumps to 6 ft – 6 ft from the SSW, still with that lovely 16-second period on Saturday afternoon. The combined energy jumps up to 1766, which is decent. Still, the SSE wind is cross-off at 25 km/h, keeping it clean, but it’s still described as marginal. Not a standout, but the trend is heading in the right direction.
Sunday the 6th through to Tuesday the 8th of September sees the swell stick around 7 ft to 7 ft from the SSW, with periods around 13-14 seconds. The combined energy climbs into the 2200-3300 range – that’s strong wave energy now. But on Tuesday afternoon and into Wednesday the 9th, the wind shifts to straight cross from the S, which puts a bit of a chop on the surface. The swell size pushes 8 ft. That’s getting solid, but with the cross-chop it’s not the cleanest. Still, for an experienced surfer, it's worth a look.
Thursday the 10th and Friday the 11th of September see the wind drop back to a clean cross-off, with swell around 5 ft to 7 ft and periods of 15-17 seconds. The energy is strong (1737-2303). The water temp is about average for the time of year. This is where it starts to get good.
Now, for the standout. I’m looking at Monday the 14th of September. We’ve got a solid 8 ft swell from the SW, with a 16-second period, and a clean cross-off breeze. Combined energy is a beastly 2902. This is the best on offer. The reef at Ekas-Outside will handle that long-period groundswell beautifully. The 16-second period means long, clean lines, and you'll have time to paddle out between sets. That’s a session worth marking in your calendar. It is a beginner-friendly reef, but at 8 ft, beginners might find it a bit much – this one's for the crew with a bit of confidence. Crowds are just sometimes, so you might get some company.
Tuesday the 15th and Wednesday the 16th hold similar size, around 7 ft to 7 ft from the SW, but the wind freshens to 30 km/h from the SE, still cross-off, so it stays clean. The energy is strong (2052-2322). A solid run.
By Thursday the 17th of September, the swell eases to 6 ft-6 ft, and the wind becomes a gentle breeze. Still clean.
Then look at Friday the 18th of September. Swell is 5 ft from the SSW, period 14 seconds, and a gentle breeze from the SE makes it glassy. The combined energy is 1437 – moderate, but the forecast actually calls this one "excellent surf conditions for experienced surfers." It’s the cleanest, most user-friendly swell of the whole run. That’s your other standout. If you want smaller, cleaner, and more manageable, this is the day.
The first few days are a write-off in terms of quality. There’s a gap from Thursday the 3rd to Friday the 4th of September with no real recommendation, then it slowly builds. No big gaps after that.
Stay stoked.
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.
