The Lowdown
Hey folks, Rusty here. We're looking at a strange fortnight ahead, with some proper surf lurking in there, but you'll have to be patient. The start of the run isn't huge, but it's clean. The standout is hiding away about a week out, so don't be sleeping on the forecast.
The first few days, from Friday the 11th through the weekend, are all about small, clean waves. Friday morning is ankle to waist-high, right around 3ft of southwest groundswell. The period is a solid 16 seconds, which means there's some energy in the water, but it’s small. The wind is light easterly, so it's cross-off and the surface is clean. It's surfable, but it's a longboard kind of session. The energy is low. Saturday is pretty similar, 2ft on Saturday afternoon, and it goes glassy with zero wind. You can score a few soft ones. Sunday is even smaller, down to 2ft, and while it's glassy, it's really weak.
Monday the 14th starts small, but the afternoon gets interesting. The period jumps up to 22 seconds and the energy picks up. Swell is still only 2-2ft, but that long period is something else. Then, Tuesday the 15th is where things wake up. Morning sees the swell bump to 3-3ft from the SSW with a 20-second period, and the energy jumps to 531. This is the standout of the whole run. The wind is light easterly, leaving it clean. It's still not big, but it's going to have some proper shape.
Now, the second half of the week gets trickier. Wednesday thru Friday the 18th, the swell pushes up to 3-4ft and the energy is strong – we're looking at numbers up to 729. But the trades are up. 25-30 km/h easterly winds are going to put a real chop on the surface. It’s not going to be the clean surf we had earlier. It’s more of a battle. The energy is there, but the quality drops right off.
We settle back into a more mellow pattern from the 20th to the 22nd. Waves drop back to 2-3ft with moderate energy. It's clean for the most part, especially Tuesday morning with glassy conditions.
The window around the 23rd to the 25th gets interesting again. The 23rd is small but glassy, which is nice. The real promise is for Friday the 25th. The swell is still only 3ft, but the wind swings around to a light northerly, giving us that cross-off again, and the energy is back up to 506. That’s the one to watch for the back half. It's a bit far out, so I wouldn't bet the farm on it, but the setup looks promising.
For the standout, it's gotta be Tracks (Nanakuli) on Tuesday, September 15th. It’s got the best combo of the whole stint: a clean 3ft SSW swell, a long 20-second period, light winds, and solid energy. It won't be huge, but it will be the best quality surf on offer. Keep an eye on Friday the 25th as a promising, but less certain, second option.
Alright, that's the long and short of it. Get on it when you can.
Rusty.

Information about the Tracks (Nanakuli) Surf forecast
