The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our little corner of the lineup.
Right off the bat, we’ve got a solid run of swell heading our way. Don’t let the score fool you though – the conditions are a bit tricky. The wind is a persistent cross-off shore from the SSE and SE, which isn’t perfect but it’s keeping the surface clean. The real story here is the sheer amount of energy in the water. The combined swell energy is massive, hitting values like 1721 and climbing well into the thousands, even up to 4423 later on. That’s a lot of push, almost all of it from the SSW and SW, which is right in the sweet spot for Ekas-Inside.
The water temp is sitting at 80°F with no anomaly, so it’s bang on average for this time of year – no surprises there.
Now, the first few days from Monday the 31st of August through to Thursday the 3rd of September are a bit of a mixed bag. The swell is running 5 ft to 7 ft, but the period is a very long 18 seconds dropping to 16 seconds. That’s proper groundswell, which means deep, powerful lines. For a reef setup like Ekas-Inside, that’s actually a good thing – it should focus the energy nicely. The problem is the wind is a moderate 15 to 19 mph cross-off, which is a bit of a hassle. Still, it’s clean.
Friday the 4th and Saturday the 5th of September look like the weakest part of the run, with swell dropping to 5 ft and the period shortening to 14 seconds. The energy dips to 738 and 849, which is a noticeable drop. The surf is still there, but it loses its punch.
Here’s where it gets interesting. The second week kicks off with a proper spike. Sunday the 6th of September afternoon sees a jump to 6 ft SSW swell with a 17-second period and the combined energy roaring back up to 3097. The wind is still cross-off, but it’s manageable. Then Monday the 7th, Tuesday the 8th, and Wednesday the 9th of September really look like the window to aim for. The swell holds steady at 7 ft to 8 ft, and on the 8th of September afternoon, the direction shifts to a pure cross from the S, with the energy hitting 4423. That’s a lot of water moving.
The standout for me has to be Wednesday the 9th of September. The morning session shows an 8 ft SSW swell, a 16-second period, and the wind drops to a gentle 9 mph cross-off. That’s about as clean as you’re going to get for an 8 ft wave. The combined energy is 3195, which is plenty. This is the pick of the fortnight for experienced surfers. For beginners, that 8 ft height is getting into the “too big” zone, so know your limits.
The rest of the week into the 15th of September keeps the swell pumping, with 7 ft to 8 ft consistently, but the wind picks back up to a moderate to fresh breeze. It’s still surfable, but the magic of that Wednesday morning will be hard to beat. Also, keep in mind that Ekas-Inside is a fairly consistent reef break, so it handles this kind of swell well. Crowds are listed as “sometimes,” so keep an eye out if you want a peak to yourself.
Alright, that’s the long and short of it. Get out there for that Wednesday morning session if you can.
Rusty.
