The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the menu for the next couple of weeks.
Honestly, it’s a tough stretch ahead for Slip Point (Clallam Bay). We’re looking at a long, dry spell with very little to get excited about. There’s a big gap at the start: from Tuesday morning all the way through to Saturday afternoon, there’s absolutely nothing rideable. That’s five days of flat or junk conditions. The water temp is sitting at a very chilly 52°F, which is a massive 7°F colder than normal for this time of year – that's seriously unusual, so you’ll want a thick wetsuit and booties if you’re even thinking about it.
We finally see a little pulse of energy on Sunday, August 23rd. There’s a weak 2ft swell coming from the west, with a short period of 8 seconds. The energy is tiny (36). The wind is a cross-offshore from the east in the morning, which will keep the surface clean. It’s not going to be anything special – really just ankle to knee-high dribblers – but it’s the only window.
After that, it’s back to a whole lot of nothing. Monday and Tuesday are flat again. There’s a tiny bump on Tuesday afternoon, August 25th, with a 2ft west swell but a period of 10 seconds. The combined energy is still weak (98). The onshore wind from the NW is going to mess it up.
There are a few wobbly pulses in the last few days of August and into September, with heights around 2ft to 2ft, but any time there’s rideable swell, the wind is mostly onshore or cross-onshore, ruining any chance of quality. The very end of the month, August 29th to 31st, shows some glassy conditions, but the swell is still tiny and weak.
The standout here, if you can call it that, is the Sunday morning (August 23rd). That 2ft west swell with a clean cross-offshore breeze is your only real shot at a couple of clean little runners on the point. It won’t be memorable, but it’s the best on offer. The rest of the period is a write-off for a proper surf.
Conditions are that poor for so long that this kind of blank run is pretty normal for the area. Don't hold your breath.
Rusty.
