The Lowdown
Alright, let’s cut to the chase. The surf report for the next couple of weeks is pretty bleak. We’re looking at a whole lot of flat, onshore junk before anything even worth paddling out for shows up.
The first little tease is on Tuesday the 18th. A weak 2ft swell out of the west shows up, but the period is short and the west wind is messing it up. Wave energy is a weak 125, so it’s more of a ripple than a wave. Don't get your hopes up.
After that, we’re back to a long stretch of nothing. From the 19th through the 25th, it’s totally flat. A week or more of no surf. Time to wax the longboard and just go for a paddle, or find another hobby.
Things start to look a little more interesting at the end of the month. On Wednesday the 26th, we finally get a bit of swell, with about 4ft out of the west in the morning, dropping to 3-4ft by the afternoon. The period is still short and junky, and the wind is cross-onshore, so it’s going to be a bit of a mess. The energy is moderate at 263, so there’s some push there, but it won't be quality.
The standout, and maybe the only real window, is Friday the 28th morning. The swell is smaller, around 2-3ft out of the WNW, but the wind is light and glassy. That makes all the difference. Slip Point (Clallam Bay) could finally be clean. With a light northeast breeze and a glassy surface, it’ll be the best conditions we’ve seen in a long time. It’s a point break, so it can handle the longer-period swell, and while it’s small, it will be your best chance for a clean wave.
Saturday the 29th looks similar, with 2-3ft and glassy conditions again. If you miss Friday, this is your backup. It won't be big or powerful, but there will be some fun, clean little waves. And after almost two weeks of nothing, you’ll take it.
This is a classic case of taking what the ocean gives you. It’s not going to be epic, but at least it’s surfable. Don’t expect any barrels, just enjoy getting wet.
