The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the Strait.
Honestly, looking at the next 16 days, it's a tough stretch for us at Slip Point (Clallam Bay). The water is sitting at 55° which is a solid 4° colder than usual for this time of year, so you're gonna want a good hood and booties.
We've got a real dry spell to start. From July 30th right through the first week of August, it's flat. Days of cloudy skies, rain showers, and onshore winds from the WNW are giving us zero surf. A few mornings show clean conditions with light cross-offshore winds from the east, but there's simply no swell to ride. It's a long wait.
Finally, on the morning of Wednesday, August 5th, we get a pulse. The wind swings light and cross-offshore from the east, which is clean. The swell is a 4ft W groundswell with a 9-second period, giving us a moderate energy level (269). This is the standout of the entire forecast. It's not huge, but it's a proper surfable wave with clean conditions. Afternoon looks a bit onshore, so make the morning mission.
The morning of Thursday, August 6th, is also worth a mention. The wind is glassy from the NNE, and the swell is 4ft from the west at 9 seconds. The energy is moderate (207). It's a bit smaller than Wednesday, but glassy conditions are rare and precious here. It'll be smooth.
After that, the quality drops. The rest of the second week sees mostly cross-onshore winds and poor surf conditions. A few pulses show up, like on the morning of August 9th with a 4ft W swell, but the wind is cross-onshore, making it choppy. We get a small 3ft WNW swell on the morning of Friday, August 14th, but again, the wind isn't cooperating.
So, to sum it up: the best bet, and the only real standout, is the morning of Wednesday, August 5th. Get out there early for clean 4ft waves from the west. The glassy morning of Thursday, August 6th is a very close second for a smooth session. Everything else is a write-off.
Stay patient, stay warm.
Rusty.
