The Lowdown
Alright, mate. Rusty here again, but this time in feet and inches for you.
Let’s be straight: the next 16 days at Slip Point (Clallam Bay) are looking dead flat. From Thursday the 20th of August all the way through to Friday the 4th of September, there’s barely a ripple. The combined energy numbers are all in the weak range, with the highest being just 78 on the Saturday morning of the 22nd, and that’s still considered poor surf. Most days show zero energy.
The only bit of life comes on Saturday the 22nd of August, with a tiny 2ft swell from the west at 9 seconds. That’s a short-period windswell with weak energy (78), and the wind is onshore from the WNW. The morning has a light breeze onshore, the afternoon gets a cross-on breeze from the west – light cross-onshore with small wind ripples. Not worth paddling out for.
Tuesday the 25th of August has a 2ft west swell at 7 seconds (37 energy) with light onshore wind. Again, poor surf. The rest of the days are all zeros, with some glassy mornings but no swell to speak of.
This is a classic flat spell for this point break. It’s exposed to the WNW, and that’s the direction we need, but the swell just isn’t coming. Nothing here is a standout. If you’re a regular, you know this happens. We’ll have to wait and see if the next forecast brings some life.
Rusty.
