The Lowdown
Alright, Rusty here. Gonna be honest with you, looking at this forecast for Ekas-Inside, it’s a mixed bag of 'pretty good, but not quite firing.' The water is sitting right around 80°, which is dead average for this time of year, so no surprises there.
The main event kicks off on Wednesday the 19th of August. We’ve got a solid 8ft SW groundswell rolling in, with a long period of 18 seconds. That’s proper energy – the combined swell energy is a massive 4135, so there’s plenty of grunt in the water. The wind is a cross-off from the SSE at 12 mph, keeping things clean. This is a reef break, so that long-period groundswell will wrap in nicely, offering some well-shaped waves. It’s a bit meaty for the beginners though at 8ft. This is the standout of the whole run, no question.
The swell hangs in through Thursday and Friday, still in that 7ft to 8ft range with long 15-17 second periods. The wind stays cross-off from the SE or SSE, so the surf stays clean. The energy is still strong, in the 3000-4000 range. It’s not the peak of Wednesday, but it’s still very good, especially for those with some experience.
We then see a slow, steady drop over the weekend and into the next week. The swell drops to 5ft-7ft through Saturday and Sunday the 23rd, and the period shrinks to 14-16 seconds. The wind remains cross-off. The energy drops to the 2000-2600 range. It’s still surfable, but the quality slips a bit, and the forecast ratings drop.
From Monday the 24th through to the 27th, the surf gets smaller and weaker. We’re looking at 5ft to 6ft waves, with the period dropping to 14 seconds. The combined energy drops below 1500, so it’s becoming marginal. The wind is still cross-off, but the window for a good wave is getting narrow.
Then, on Friday the 28th of August, there’s a bit of a pulse. The swell jumps back up to 8ft from the SW with a 16-second period, and the energy spikes to 3143. The wind is a gentle 9 mph cross-off from the SSE, making for some of the cleanest conditions in the whole run. The forecast calls it excellent for experienced surfers, and I’d agree. Keep an eye on that morning session.
The rest of the run into the first week of September is inconsistent. The swell stays between 5ft and 8ft, the period bounces between 13 and 20 seconds, and the energy is moderate. The wind is consistently cross-off. There are some fun waves to be had, but nothing that screams 'drop everything and go' like that Wednesday the 19th or Friday the 28th. The forecasts are a bit uncertain for the second week, so don’t bank on perfection.
So, if you’re looking for the best of it, be on the water on Wednesday the 19th of August. That 8ft SW groundswell with the 18-second period and clean cross-off wind is the gold run. The Friday the 28th morning is your second solid chance. The rest is a bit of a waiting game.
Rusty.

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-Inside 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.
