The Lowdown

G’day, Rusty here. Look, I’m gonna be straight with you – the next 16 days are a real mixed bag, and honestly, most of it is pretty flat or just plain messy. We’ve got a long stretch of nothing much, with a few tiny windows where you might get wet, but you’ll have to work for it.

The water temperature at Slip Point (Clallam Bay) is sitting at 55° – that’s 4° colder than usual for this time of year, so it’s a bit nippier than normal. You’ll want a decent wetsuit.

We kick off from Friday the 28th of August right through the weekend with absolutely no surf to speak of – zero energy in the water. The wind is a real issue, mostly cross-onshore or onshore, chopping up any chance of a wave. There’s a four-day gap with no recommendations at all.

Then, on Sunday the 30th of August, we get a tiny pulse of swell overnight. The morning shows a weak 2 ft from the west, with a short period of 7 seconds and combined energy of just 45. It’s glassy, which is a positive, but the swell is so weak and small it’s barely worth a paddle. Monday the 31st of August morning is similar – glassy, a 2 ft west swell, but the period is only 8 seconds and the energy is 71. You might catch a few knee-high lumps, but it’s very ordinary.

After that, we hit another dry spell. From Monday afternoon through to the end of the first week of September, it’s a mix of onshore winds and no swell, with a few fleeting moments of glass but no wave energy to work with. There’s another three-day gap without any recommendations.

Things start to get a little more interesting around Saturday the 5th of September. The morning and afternoon both have a clean, cross-offshore wind from the east-southeast at 12-16 mph, which is a good sign. The swell is still tiny – 2 ft from the west, 9-second period, with energy around 59 – so it’s a small, clean little wave. Not a standout, but it’s the best we’ve seen in a while. The swell is still pretty small and weak, but the clean conditions make it rideable for a skilled surfer on a log.

Sunday the 6th of September morning is glassy, with a 1 ft west-northwest swell that has a long period of 13 seconds (groundswell) and energy of 80. The long period means the waves will have some shape and power for their size, but it’s very small. An advanced surfer might get a couple of fun ones on a point break like Slip Point, especially with the glassy conditions.

Monday the 7th of September is the best window in the whole outlook. The morning and afternoon both have a clean cross-offshore wind from the east at 6 mph. The swell is 2 ft from the west-northwest, with a period of 11-12 seconds and that energy steps up to 142 in the morning and 130 in the afternoon. That’s moderate energy. The direction is a nice match for Slip Point’s optimum west-northwest. The waves will be small, but clean, with some power from the longer period. It’s the standout session for the whole 16 days – a real sneaky little window.

After that, it’s back to the grind. The rest of the second week is mostly flat, with onshore winds and poor conditions. There’s a brief moment on Wednesday the 9th of September morning – glassy, 2 ft west-northwest swell, 9-second period, with energy of 179 – but it’s still very ordinary. In the afternoon, the swell jumps to 3 ft with a 13-second period and energy of 273, but the wind turns onshore, killing it.

Thursday the 10th of September morning is glassy calm, with a 2 ft west swell, 11-second period, and energy of 89. It’s a tiny clean wave, but nothing to get excited about.

From there, it’s a flat, windy, or rainy end to the period. The last few days from the 11th to the 12th of September have no swell at all.

So, honestly, this is a tough outlook. If you’re desperate, aim for Monday the 7th of September morning or afternoon at Slip Point – it’s the cleanest, most promising session with some moderate energy. Otherwise, you’re better off waiting for the next forecast. The area is known for long flat spells, so this isn’t unusual, but it’s still a drag.

Rusty.
