The Lowdown
Alright, here’s the deal. The next couple of weeks are all about one spot, and that spot is Ekas-Outside. It’s a reef break, pretty consistent, and it’s holding all the swell. The water’s around 80°, which is pretty much average for this time of year, so nothing crazy.
We’ve got surf starting from Thursday the 20th and it’s not gonna let up. The first few days, through the weekend and into next week, are all about that solid 7ft to 8ft SW swell. It’s got some punch to it with periods in that 15-16 second range, real groundswell. The wind is cross-off from the SE, keeping things clean, though it’s a moderate breeze at times. The energy’s there, but it feels like it’s just under that top tier, with combined energy readings in the 2000s to 3900s. It's surfable, for sure, but not gonna blow your mind.
The swell dips a bit midweek, dropping to around 6ft, but it’s still there. Then we get a bit of a pulse on the 27th with a longer period, and the energy climbs again. But hold on, because the real standout is coming.
The morning of Friday the 28th is where things start to get properly exciting. That 8ft SW swell at 16 seconds, with a gentle cross-off breeze—that’s a recipe for some proper clean waves. The energy jumps to 3331, and it’s shaping up to be the best conditions for experienced surfers in this whole run. This is the one to aim for.
But if you can wait, the real jewel is on Tuesday the 1st of September. That’s a week and a half out, so treat it as a promising forecast, but it’s got everything. A 10ft SW groundswell with an 18-second period. The energy reads 5654, which is strong, and with that light SE wind, it’s gonna be firing. This is a bigger, more powerful day; over 8ft, so this is for experts only, no messing around. That’s the best on offer, no question.
The couple of days after that settle back down to a solid 7-7ft, still decent. The second week is more of the same, with the swell easing gradually. From the 3rd and 4th of September, we’re looking at 5ft to 6ft surf, dropping off into the tail end of the window. Energy readings are in the 1000s, so it’s weaker, but there’s still something to ride.
So, in short, there’s surf on tap all through. The standout is that big pulse on the 1st of September. The 28th of August is the pick before that. Keep your eye on those days.

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.
