The Lowdown
Alright folks, Rusty here. Let’s have a look at what's on the cards for the next couple of weeks at Slip Point (Clallam Bay).
Right now, it’s flat and ugly. For the next week and a half, there’s barely a bump. A few tiny 2ft waves from the west might show up on Tuesday the 25th, and again on Saturday the 29th, but the real story is the wait. You’re looking at a massive gap of quiet water, with the next real shot of something happening not arriving until Thursday morning the 3rd of September.
That Thursday the 3rd is the standout. We’ve got a proper pulse of groundswell rolling in: 4ft from the west, with a long 11-second period. The combined energy is a solid moderate to strong 326. That’s the sort of energy that builds proper lines. The morning sees clean conditions with a light cross-offshore breeze from the east, and this spot is a point break, so it’ll soak up that longer-period energy beautifully. The water is sitting at a chilly 54°, which is a massive 5° colder than average for the time of year – you’ll want a good thick wetsuit.
Come late Friday the 4th and into the weekend of the 5th and 6th, the swell backs off, dropping to 2-3ft, but the winds turn clean again with a light offshore from the east. The period drops too, so it won’t have the same grunt, but those mornings will be surfable. There’s another blob of swell showing for Tuesday the 8th, but the wind swings to the west and onshore, which will be a mess for a point break like this – that size and onshore wind might actually look better for kite surfing than paddling.
If you’re set on a dip, that Thursday the 3rd looks like your day. Clean, solid lines, and the biggest swell of the window. Just be aware that this spot can have crowds from time to time. The rest is a waiting game.
Rusty.
