The Lowdown
Alright, Rusty here. Let’s talk about what’s brewing for Slip Point (Clallam Bay).
Look, I gotta be straight with you – the next week and a half is looking pretty grim. We’ve got a long dry spell ahead. From Saturday the 15th right through to Saturday the 22nd, there’s basically nothing doing. The swell is flat, and even when the wind goes glassy on Tuesday morning the 18th or Thursday morning the 20th, there’s just no wave energy to work with. It’s a real bummer for a spot that’s fairly exposed to the swell. You’ll see some light offshores and clean conditions on Wednesday the 19th and Saturday the 22nd, but still no swell to speak of.
Finally, on Sunday the 23rd, we see a tiny pulse of life. A small 2ft west swell with a short 8-second period rolls in, but the combined energy is weak (66). It’s a cross-offshore breeze from the east in the morning, so the surface will be clean, but honestly, this is barely rideable. It’s not going to be worth paddling out for most.
The next glimmer comes on Wednesday the 26th. Another 2ft west swell, period up to 9 seconds, but energy is still weak (79). Conditions are unknown in the morning with a light breeze, but it’s not enough to get excited about.
The very end of the outlook shows a ray of hope. On Sunday the 30th, we’ve got light glassy conditions and a clean surface in the morning with a 2ft west swell, period 7 seconds, and energy at 44. It’s still tiny and weak, but at least the wind is calm.
The standout? Honestly, there isn’t one in this 16-day window. If I had to pick the best chance for a splash, it’d be Sunday the 30th for the glassy conditions, but don’t expect any real power. For the advanced surfers who call this place home, it’s a waiting game. Flatter periods like this are normal here, so don’t lose hope – forecasts change, and it never stays poor for long.
Rusty.
