The Lowdown
Right then, let’s have a look at what we’ve got for the next couple of weeks here. I gotta be straight with you – it’s a pretty lean run for Slip Point (Clallam Bay). The water’s sitting at 55°, which is a couple of degrees cooler than what we’d usually expect for this time of year, so that’s a bit of a nippy one.
We’ve got a long gap here with no real surf to speak of. From now until the end of August, you’re looking at flat, poor conditions. A bit of a ripple on Saturday the 29th with a light cross-onshore wind and nothing underneath it. Sunday the 30th is glassy but still flat. It’s not until Monday the 31st that we finally see a tiny swell creep in. We’re talking a weak 2 ft from the west with a short, 8-second period. The energy is really low at 52, so it’s barely a wobble. The morning has a clean, cross-off breeze, so if you were desperate for a knee-high dribbler, that’s your window.
Tuesday the 1st of September is more of the same, with 2 ft west swell and a 9-second period, but the wind goes onshore and lumpy in the afternoon. The energy is still weak at 78.
Then we hit another dry spell. From the 2nd through to the 4th of September, it’s pretty much flat again. Glassy mornings and clean afternoons, but no swell to ride.
Saturday the 5th of September shows a glimmer – 2 ft west swell again with a 9-second period, but the glassy morning gives way to a bumpy cross-onshore breeze in the afternoon. The energy is still weak at 59.
The best of a pretty average bunch looks like Sunday the 6th of September. It’ll be tiny – only 2 ft in the morning – but glassy. Then, by the afternoon, a long-period 1 ft swell from the WNW with a 13-second period rolls in. That’s a proper groundswell, and the energy picks up a bit to 93, which is still weak but the most we’ll see. The wind goes clean and cross-off. This swell will be very long period, so at a point break like Slip Point, it might actually wrap in and give you a few clean, waiting waves. It’s nothing to write home about, but it’s the standout window of the whole forecast.
After that, it’s mostly flat again until Thursday the 10th of September. The morning shows a 2 ft west swell with a 10-second period and a clean offshore breeze. The energy hits 104, which is at least moderate. That’s the other tiny highlight.
But honestly, for the rest of the run, it’s knees or nothing. We’re talking 0.7 ft and 1 ft drivel. Don’t get your hopes up on this one. It’s a tough stretch for the Clallam Bay crew.
