The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Slip Point (Clallam Bay) over the next couple of weeks.
Honestly, I’ve got to be straight with you – this is about as quiet as it gets. We’re looking at a long stretch of flat to tiny, sloppy surf with only a few flickers of something rideable. The water temperature is sitting at 53°F – that’s 6°F colder than usual for this time of year, so it’s much colder than normal. You’ll want a thick wetsuit.
The first real chance of anything comes on Saturday, August 22nd. The morning shows a small 2ft swell from the west with a period of 9 seconds and weak energy (78). The wind is straight onshore from the WNW, so it’s not going to be pretty. That afternoon, the swell drops to 2ft from the west with a shorter 8-second period, and the wind swings cross-onshore from the west. Look, it’s poor surf, but it’s the only wave in town that day.
Sunday the 23rd is a write-off – tiny, onshore junk. Monday the 24th morning has clean conditions with a light east cross-off breeze, but there’s no swell to speak of. Tuesday the 25th morning gives us a tiny 2ft west swell with a 7-second period and weak energy (24), but the wind is onshore from the northwest. Not great.
There’s a gap of absolutely nothing worth mentioning until Saturday, August 29th. That Saturday morning offers a 2ft west swell with a 6-second period and weak energy (28), but the wind is a light cross-off from the east, so it’ll be clean. It’s small, but if you’re desperate for a paddle, that’s your best bet in the whole window.
Sunday, August 30th morning has a tiny 1.0ft swell from the WNW with a 9-second period and weak energy (15), and the wind is glassy from the WNW. It’s clean but tiny. Monday, August 31st morning is glassy again but flat. After that, it’s back to nothing but onshore wind and flat water right through to September 4th.
If you’re a kiter, those afternoons with 12-15 mph onshore winds might look more interesting than surf. For the rest of us, this is a tough stretch. The break is inconsistent at the best of times, and right now it’s a blank run. Conditions can change, but for now, don’t hold your breath.
Rusty.
