The Lowdown
G’day, Rusty here.
Look, I’m gonna level with you – it’s a tough stretch ahead for Slip Point (Clallam Bay). The next 16 days are pretty much a write-off for decent surf. We’ve got a bit of energy kicking around, but it never lines up right. The whole period is plagued by onshore or cross-onshore winds from the NW, WNW, and W, which just shred any chance of clean faces.
The whole first week is dead. From the 13th of August right through to the 24th, there’s nothing worth paddling out for. You’ll see some tiny bumps of 1.0ft to 2ft on the 14th, but with a short period of 7 seconds and a NW wind blowing straight on, it’s just messy whitewater. The combined swell energy is weak, sitting around 10 to 49, so there’s no grunt in it. The water temp is a brutal 53°F, which is a massive 6°F colder than normal for this time of year – that’s very unusual and will feel bloody freezing.
There’s a brief flicker of hope on the 20th of August – the wind goes glassy in the morning from the WSW, but with zero swell, it’s just a flat, pretty ocean. That’s your lot for the first 11 days. A long, dry gap.
Round about the 24th of August, we finally see some weak swell return. Monday afternoon has 2ft from the west at 7 seconds, but it’s wrapped in a moderate cross-onshore breeze from the WNW, making it choppy and poor. Combined energy is 57. Then on the 25th of August, Tuesday morning, we get a similar 2ft from the west, a 6-second period, and a light onshore wind. It’s weak (64 energy) and won’t hold its shape. The 28th of August offers a morning with glassy conditions and 2ft from the west, period of 7 seconds, and calm wind, which is the cleanest window in the entire 16-day run. But the swell is still small and weak (45 energy), and it’s for experts only due to the setup.
Honestly, there are no standouts here. The best on offer is the morning of the 28th of August, but it’s a marginal call at best. The rest is just flat or blown out. For this area, a quiet run like this isn’t out of the ordinary, so don’t get too bummed – forecasts can change.
Rusty.
