The Lowdown
For the Imperial Crowd
Alright, let’s be real. The first few days of this stretch are a bust. We’re looking at a gap on the 15th and 16th with nothing worth suiting up for. That Saturday wind is a solid 25 mph from the ENE, making it tough to even get past the shore pound. The waves are small and weak. You’re better off doing something else.
We get a little something on the 17th and 18th. The swell is around 3 to 3 feet, but the period stretches out to 13-14 seconds, giving it some life. The wind eases to 12 mph from the E, holding it clean. It’s not epic, but it’s a start.
The first true highlight is Thursday the 20th. A cleaner SW groundswell with a period of 17-18 seconds rolls in. The wind goes light and offshore, and the morning looks glassy. This is the good stuff. It’s only about 2 feet, but the quality and the clean conditions will make it feel much better. This is when Tracks (Nanakuli) will have some proper shape.
The morning of Saturday the 22nd is another cracker. It’s dead glassy with a light air from the E, and a solid 3 feet of SSW swell with 16-second period. It’ll be clean and lined up. A great window before the wind clocks around in the afternoon.
The next week stays surfable but less exciting. The size stays in the 2 to 3 foot range with moderate cross-off winds. The real standout in the second week is the morning of Tuesday the 25th. The energy jumps to a solid 348, then hits a strong 443 in the afternoon with a 15-second period and offshore wind. That’s the most push we’ve seen in a while, and Tracks will have some real power.
Wednesday the 26th is a big one on paper. The morning energy hits a strong 722. The swell is still only about 3 feet from the SSW, but that energy number tells you there’s some serious grunt behind it. The wind is a cross-off, keeping it clean. It’s a promising sign for the end of the run, but it’s far out, so keep your fingers crossed. Water temp is about normal for this time of year.
So don’t let the slow start fool you. There are a few clean, lined-up sessions on the 20th, 22nd, and especially the 25th and 26th that could be well worth the wait. The long-period groundswell is perfect for this kind of setup, so Tracks is the spot to be.
