The Lowdown
Alright, let’s get this surf outlook rolling. This is your local surf reporter Rusty, and I’ve been staring at the charts for Ekas-Outside.
Alright, let’s start with the big picture. We’ve got a solid 16-day window of persistent south-west groundswell hitting this exposed reef at Ekas-Outside. It’s a classic setup: the optimum swell is from the SSW, and that’s exactly what we’re seeing for the entire run, so the reefs are going to be lit up. The water temp is sitting at 80°F, which is spot on average for this time of year. Nothing weird there.
For the first standout session, you have to look at Saturday morning, August 29. That morning is showing a 6 ft swell from the SW with a very long period of 15 seconds. That’s proper groundswell energy, and the combined wave energy is a hefty 1687 (strong to very strong). The wind is steady from the SE at 9 mph, which is a clean cross-offshore breeze. That means the surface will be clean and lined up. This is where the experienced surfers are going to have a field day. It’s a little meaty for beginners at this size, but for the crew that knows what they’re doing on a reef, it’s on.
We then roll through a few days that are still surfable but not as pristine. Sunday and Monday are still pumping, but the energy feels a touch less focused. Still plenty of waves, but the wind picks up a few notches through the afternoons. The best of the early week action is really the mornings, before the wind gets stiffer.
Looking further ahead, the whole first week of September is a solid run of clean, cross-off wind and waist-to-chest high swell. A lot of it is marked as “marginal” by the models, but don’t let that fool you – for a reef that handles this direction, it’s far from a write-off. The consistency is fairly consistent, so you won’t be sitting there for ages waiting.
Now, if you’re looking for the second true standout, keep your eyes on Tuesday afternoon, September 8. That afternoon pumps out a combined wave energy of 3844 (strong to very strong), with a 5 ft swell from the SSW and a very long period of 19 seconds. That is an incredibly long period for this stretch. That kind of energy, combined with a gentle 9 mph SE cross-off, is going to produce some absolute lines. The caveat for this one is that a 19-second period groundswell can make beach breaks a bit wonky, but on a reef like Ekas-Outside, it’s a dream. The waves will be thick, fast, and consistent.
The second weekend is also looking promising. Saturday morning, September 12 and Sunday morning, September 13 are both showing 7 ft SW swell with a 16-second period and gentle cross-off winds. On Sunday, the forecasts are calling that “excellent surf conditions for experienced surfers”. That’s the pick of the back half of the window. It’s a bit of a beast at that size, so leave the soft tops at home.
Overall, this is a classic, run of consistent SW groundswell for Ekas-Outside. The early window (August 29) is the cleanest, and the September 8 window is the most powerful. It’s going to be good out there.

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.
