The Lowdown
Alright folks, Rusty here. Let’s break down what’s on the cards for Ekas-Inside over the next couple of weeks. This is a sheltered reef break, and the water temp is sitting at 79°F, which is about normal for the time of year.
The overall picture shows a solid run of surf, but it’s a bit of a mixed bag with the conditions. There's consistent swell from the southwest, but the trade winds are blowing from the southeast, putting us in a cross-off wind almost the entire time. That keeps the surface clean, but never truly glassy. The energy is moderate, with values jumping around between 800 and 2000 for most of the period.
We kick things off on Monday, September 14th, with swell around 6 ft from the SW. It’s a long-period groundswell at 16 seconds. The energy is moderate (1930), but the wind is a cross-off at 16 mph, which keeps things a little bumpy. It’s clean-ish, but the scores suggest it’s not a standout.
The days roll by with similar conditions: consistent swell between 5 ft and 7 ft, periods holding in the 14-16 second range. The wind stays cross-off from the SE or SSE, mostly at 9-16 mph. The energy stays in the moderate zone. Friday, September 18th morning shows a small uptick in the vibe with a "very good" call – still 6 ft SSW swell, with a gentle breeze.
Now, the first real standout pops up on Sunday, September 20th. The morning sees a solid 7 ft SW swell, long period at 16 seconds. The combined energy jumps to 2067, and we finally have a gentle breeze. This is where things get interesting. It's a good call for experienced surfers as the size is pushing into the bigger range, but it’s clean and powerful.
The pattern continues with a few days of smaller, cleaner waves, then we get another highlight. On Saturday, September 26th, the afternoon session is calling for excellent conditions for experienced surfers. The swell is 7 ft from the SSW, period 15 seconds, and the energy is substantial at 2039. The wind is light, which will make for some proper lines on this reef.
And then, the big one. Sunday, September 27th. This is the true standout of the entire forecast. The afternoon shows a massive 10 ft SSW groundswell with a very long period of 20 seconds. The combined energy is a whopping 7759 in the morning, and 7496 in the afternoon – that’s very strong energy. This is expert-only territory. The wind drops to a light 6 mph cross-off in the afternoon. That is world-class potential, but you need to be on your game. The long period makes it perfect for this reef setup.
That big swell winds down on Monday the 28th, staying over 8 ft, before settling back to the 6 ft to 6 ft range by the end of the month. The closing days are similar to the start: clean, cross-off winds, modest swell.
So, the pick of the bunch? Without a doubt, the afternoon of Sunday, September 27th is the one to circle. The size, the period, the energy, and the light wind are all firing for the experts. The week before that, Saturday the 26th afternoon offers a smaller but still excellent window. There are no gaps in the swell here, just a steady run of surfable waves, with those two sessions standing head and shoulders above the rest.
Stay safe out there.
Rusty.
