The Lowdown
G’day, Rusty here. Straight talk: Slip Point (Clallam Bay) is looking like a total bust for the next two weeks. I’ve combed through the whole stretch and there isn't a single session worth paddling out for. It's a long, dry spell, and it's going to feel like forever if you're waiting for a wave.
The first sign of any energy doesn’t even show up until Wednesday the 19th. Even then, it’s just a weak 2ft of short-period slop from the west with a pitiful 6-second period. The combined swell energy is weak at 31, and the water temp is a frigid 53°, which is nearly 6° colder than normal for this time of year. That’s not just a cool change; that’s a proper anomaly, so you’d be in a full 5/4 and booties, no doubt.
Things don't improve. There are a couple of pulses, but they're all useless. The morning of Sunday the 23rd has 2ft from the west, with a 7-second period, and there's a clean cross-off breeze. But the combined energy is still weak at 52, and that period is way too short to get a point break working. The swell direction is from the west, which is near the WNW optimum, but it's still just a ripple.
The days just roll on. The 24th has a similar 2ft, but the afternoon turns choppy. The 25th sees a longer 9-second period from the WNW, but the height drops to a tiny 1ft, and the wind is cross-onshore and choppy. The 28th has a clean 2ft on Friday afternoon, but it's still nothing. The 29th has a 1ft wave with a 10-second period, but it's onshore. Just a constant run of poor surf conditions.
The only thing even close to a best-of-the-bunch would be the morning of Sunday the 23rd – but that's a big stretch. It's the biggest of the run and the cross-off wind makes it clean. But with weak energy and a short period, and barely knee-high surf, it's still not a surfer's day. It's close to being a kite-surfing session rather than a paddle-surfing one, and that says it all.
Honestly, this is a blank run. There's no consistency to hold onto. Forecasts can change, but right now, I wouldn't hold my breath. The board stays on the rack.
Rusty.
