The Lowdown

Alright, Rusty here, let's get into it. We're looking at a pretty quiet stretch ahead, so don't get too excited just yet.

Right off the bat, we have nothing happening. The first couple of days are a total write-off, with flat conditions. The earliest we see anything worth a paddle is on Friday, September 4th. Even then, it's marginal.

The only spot on the menu is Slip Point (Clallam Bay). It's a point break with an advanced rating, so this isn't for beginners. It's fairly exposed to the swell and works best with the wind out of the southeast.

The water temp? It's about average for this time of year, nothing crazy to report.

Okay, fast-forward to the first real chance. On Friday, September 4th morning, we've got tiny 2ft swell from the west with a 9-second period. The combined energy is weak at just 83. The real highlight here is the wind: it's glassy. That's about the only thing going for it — the surf is ordinary at best. The afternoon goes flat again.

The rest of that first week is a struggle. Saturday morning (September 5th) sees the swell drop even smaller to 2ft, and the energy is weak (56). There's a clean, cross-offshore wind though, which is nice, but the waves are tiny.

Sunday, September 6th morning is interesting for the period geeks. That 1ft swell sneaks in from the WNW with a very long 13-second period. Groundswell energy is still weak at 83, but that long period means the sets will be clean and lined up on the point. The wind is light and cross-offshore, so it'll be clean.

Monday, September 7th? Poor conditions. Same story for most of the week. A lot of cross-onshore junk and next to no size.

We finally see a bump on Saturday, September 12th morning. Swell comes up a touch to 3ft from the WNW, but the period is short at 8 seconds. The energy is still weak (85). The wind is a clean cross-offshore, making it surfable, but nothing to write home about. The afternoon goes glassy but the swell backs off to 2ft.

Tuesday, September 15th afternoon might be the most interesting call of the whole run. The swell is only 2ft from the west, but here's the kicker: the period hits 14 seconds. That's a very long period groundswell. The combined energy jumps to 144 — moderate energy for once. Unfortunately, the wind is a moderate cross-onshore at 12 mph from the WNW, so it'll be choppy. This is the strongest energy signature in the whole outlook, but the onshore wind kills the quality for paddle surfing. For an advanced crew, maybe you can snag a few clean ones between the chop, but it's a tough sell.

Wednesday, September 16th morning sees that 2ft, 12-second period groundswell hanging around with moderate energy (108) and a clean, cross-offshore breeze. It's surfable but ordinary.

All in all, if you're desperate for a paddle, the glassy windows on September 4th morning or the clean cross-offshore on September 12th morning are your best bets, but the waves are tiny. The bigger energy on the 15th is there, but it's blown out. For a spot that's inconsistent and only for experts, it's a frustrating run.

Rusty.
