The Lowdown
Gutted, honestly. We’ve got a blank 16-day window ahead for Slip Point (Clallam Bay) and there’s no pretty way to spin it. It’s a rare spot, and it’s staying that way for a while. No proper swell, no real quality, just a whole lotta nothing on the horizon.
The water’s running 53°, which is a massive 6° colder than normal for this time of year. That’s not just a little chilly – that’s a whole different season. You’ll be needing a thick hood and gloves if you even think about paddling out.
Looking through this stretch, there are a few tiny pulses of wave energy, but they’re doing absolutely nothing for us. Saturday the 22nd has our biggest showing – a weak 2ft of west swell with a short 9-second period and energy sitting at just 64. It’s poor, onshore wind, and completely forgettable. Not worth getting out of bed for.
Tuesday the 25th gives us a similar story with a 2ft west swell, even shorter at 7 seconds, and weak energy of 49. Clean-ish in the morning with light offshore, but the swell is just too small and gutless. You might see a few ankle-biters, but that’s about it.
From the 27th onward, we’re just fading into nothing. The energy drops into single digits by the 29th. There are some clean, glassy mornings – the 31st in particular – but there’s nothing to ride. A point break like this needs proper groundswell, and we’re getting zilch.
Yeah, it’s a painful outlook. With some decent morning conditions but no swell, this is looking way more interesting for the kitesurfers than anyone on a surfboard. Forecasts can change, but right now, I’d find something else to do for the next couple weeks.
