The Lowdown
Alright, Rusty here. Let’s talk about what’s on the table for Slip Point (Clallam Bay).
Look, I'll be straight with you: the next couple of weeks are pretty bleak around here. We’re looking at a long, quiet spell with more flat days than I’d care to count. There's a solid stretch from now until August 23rd where there’s just nothing doing – just poor surf conditions day after day. You won't find a wave worth paddling for until Sunday the 23rd, and even then, it’s not going to set the world on fire.
Now, the water temperature is sitting at 53° – that’s a whopping 5° colder than normal for this time of year. So if you do go in, it’s going to feel proper chilly. That’s very unusual.
On the morning of Sunday the 23rd, we finally see a little pulse of life. A small, weak swell rolls in from the west about 2ft, with a period of 9 seconds, so it’s short-period wind swell, not much grunt behind it. The combined swell energy is just 76, which is weak. The east wind will be blowing cross-off at 6 mph, keeping things clean, but it’s hardly a stand-out. For a more experienced surfer, it might be worth a look for a slow, mellow session.
After that, it’s back to square one. The 24th and 25th are onshore and choppy. Then we get a couple of glassy mornings on the 26th, 27th, and 28th, but there’s almost no swell to work with – just tiny 2ft to 2ft waves with short, wobbly periods of 6 to 7 seconds. The energy figures are in the 20s, barely registering. You could get a clean little knee-high wave on a glassy morning, but it’s not really surf.
The only other flicker comes on the 28th afternoon and the 29th morning, with a little 2ft and 2ft west swell, but conditions are either choppy or just average. Nothing here pulls me out of bed.
Honestly, the best call of the whole 16 days is that Sunday morning, the 23rd. It’s clean, it’s surfable, and it’s the only window with a wave and half-decent wind. Don't hold your breath for the rest.
Rusty.
