The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on offer around Slip Point over the next couple of weeks. I’ll be straight with you – it’s a bleak stretch for surf, no two ways about it. The data shows a whole lot of nothing for days on end, with only a few tiny windows where you might get wet.

The pattern is pretty grim. We’re looking at a long, flat spell broken only by a few pulses of very weak, short-period windswell. There’s a big gap right at the start with absolutely no surf to speak of on Saturday the 29th – just a cross-onshore breeze and flat conditions.

The first real chance to paddle out comes on Sunday morning, August 30th. Slip Point (Clallam Bay) will see a tiny 2ft swell from the west, with a short period of 9 seconds. The energy is weak (76). The good news is the wind is glassy, dead calm. The water is sitting at 55°, which is a notable 4° colder than usual for this time of year, so you’ll want a thick suit. It’s not going to be anything to write home about, but a glassy morning on a tiny wave is better than a day at work.

Monday morning, August 31st, offers a repeat performance: 2ft of west swell, still skinny on period at 10 seconds, and weak energy (94). A light easterly cross-offshore breeze should keep the surface clean-ish. It’s surfable, but just barely.

After that, the forecast goes totally flat again. From Tuesday the 1st of September all the way through to the morning of Tuesday the 8th of September, the waves are either non-existent or too blown out and messy to bother with. Paddling out is not worth the squeeze.

We get a slight glimmer of hope on Wednesday morning, September 9th. The combined swell energy jumps to 143, which is still only moderate, but it’s the best we’ve seen. We’re looking at a 2ft west swell with a very long period of 13 seconds. That’s a proper groundswell, but it’s tiny. A clean cross-offshore breeze from the southeast will tidy it up. This long-period groundswell, even at this size, will work best at a point break like Slip Point.

That’s your one standout, and it’s more than a week away, so don’t book a trip around it. The last hope is Friday morning, September 11th, where we see a 3ft swell from the west-northwest, but the period is a weak 8 seconds and the wind is cross-shore, making for poor, chopped-out conditions. Not recommended.

All in all, it’s a long, quiet stretch. The small windows on August 30th and 31st are your best early bets, and if you’re patient, the clean, tiny groundswell on September 9th is the one to watch.
