The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the menu for the Olympic Peninsula stretch.
Alright, so I gotta be straight with you – the next week and a half is gonna be a tough watch. We’re looking at a dead stretch of ocean with zero swell energy for the better part of two weeks. It’s not until we get into the second week of August that we finally see a little pulse of life.
The first real chance to get wet comes on Tuesday, the 4th of August. Slip Point (Clallam Bay) finally sees a little bump of energy. We’re talking a weak swell, only about 2 ft from the WNW, with a short period of 7 seconds. The combined energy is a meek 32 (weak energy). Not gonna set the world on fire. The real highlight, though, is the following morning. Tuesday afternoon, the 4th, the wind goes glassy with a light NE breeze, and we’ve got about 2 ft of W swell. The water is running about 52°, which is a whopping 6° colder than normal for this time of year – that’s seriously unusual, so bring a thick hooded suit, you’ll feel it.
The absolute standout window is the morning of Tuesday, the 11th of August. We’ve got a clean, cross-offshore breeze from the ENE, and the swell pushes up to 2 ft from the west with a period of 8 seconds. The combined energy hits 64 (still weak, but it’s the best we’ve got). It’s not huge, but with that clean wind and the conditions aligning, it’s the best bet in a very long, flat spell. Crowds are possible here, but on a day like this, with a tiny swell, don’t sweat it.
The swell sticks around, but the wind gets tricky. By Wednesday the 12th, it’s back to a cross-onshore breeze, knocking the quality down with a tiny 1 ft wave. The short 7-second period means it’ll be weak and mushy.
So, bottom line: the first week is a total washout. The 4th of August offers a tiny, glassy window, but the real best bet, and the one true standout, is the clean morning of Tuesday, the 11th of August. Keep your expectations low, but it’s something to aim for.
Rusty out.
