The Lowdown
Alright, Rusty here, checkin' in from the coast. Let's get straight to it.
Mate, I gotta be honest with ya – the next 16 days look like a proper desert for surf around Slip Point (Clallam Bay). The finder's come up with nothing, not a single decent recommendation in the whole window. We're looking at a long, dry spell.
We start off on Friday, August 14th, with a tiny, weak 1 ft swell from the WNW at a short 7 seconds, and the wind is onshore. The water's sitting at 53°, which is a solid 6° colder than normal – that's real unusual for this time of year, so you'll be needing a thicker suit for sure. The combined energy is a measly 10, so there's just nothing to work with.
From there on, it's pretty much a washout. The swell completely drops out for days on end. We get a little blip on Tuesday the 18th afternoon with a bit more energy coming in at 125 from the west, but the wave comment says it's poor and the swell is still only 2 ft. It's a long period groundswell at 13 seconds, which is nice for shape, but it's just not big enough.
We see some glassy mornings and clean conditions here and there, like on Tuesday the 25th morning or Thursday the 27th afternoon, but with no swell to speak of, it's a flat calm. The whole period is just a series of poor surf conditions with tiny, weak swells and onshore winds keeping things messy. The biggest swell we see is a 2 ft from the west late on Monday the 24th, but the energy is still weak at 47 and the wind is light cross-onshore.
Even the last few days of the forecast, around the 28th and 29th, show the same story – tiny swells, glassy mornings, but nothing to ride. The longest period of zero swell is from the 15th to the 17th, and then again from the 19th to the 21st. It's a tough run.
When the surf is this consistently flat and the conditions are generally poor, it's just a waiting game. Forecasts change, and it won't stay this way forever, but for now, leave the boards in the car. The only thing moving out there might be the leaves in the trees.
Rusty.
