The Lowdown
Alright, Rusty here, lookin’ at your local stretch. Man, it’s slim pickins. Mostly flat or just ankle-biters.
Your best shot is Monday, August 31st, at Slip Point (Clallam Bay). We’re talkin’ a small 2ft swell out of the W, 10-second period, with a combined energy of (90). What makes it special is that glassy wind out of the NNE at just 3 mph. It’ll be clean as a whistle. Water temp is a chilly 54°, which is a solid 5° colder than normal, so you’ll want the 5/4. That’s the highlight, because that next morning on Tuesday the 1st the wind goes cross-onshore and it’s over.
From Tuesday afternoon all the way through Friday the 4th of September, it’s a total flat spell. Clean skies, but no swell to ride. Saturday the 5th of September brings back a tiny 2ft W swell, but it’s just ordinary.
Things stay quiet until Monday, September 15th. The morning of Tuesday the 15th shows a small 2ft WNW swell, but with a 12-second period and combined energy hitting (140) – the most energy in the whole run. The trade off is a solid cross-offshore ESE wind at 12 mph. It’ll be a battle, but that’s the only real power spike. By the afternoon the swell drops to 2ft and the wind backs off, making it more manageable but weaker.
Not a ton to get excited about here. That first Monday afternoon is your cleanest, most surfable window. The rest is a whole lot of waitin’. Forecasts can turn, so keep an eye on it, but for now it’s mostly a time to get the gear sorted.
Stay patient.
