The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.
The short story is, we’re in a long, slow patch. The first serious stretch has basically nothing ridable for you, and it’s not until well into the first week of September that we start to see a little pulse of energy. Even then, it’s mostly small and marginal. The standout in the whole window is a brief window on the morning of the 2nd of September, and a cleaner run of small but workable conditions from the 5th into the 6th of September.
Let’s run through it day by day. Starting now, Tuesday the 25th of August, there’s a tiny 2 ft, 7-second W swell at Slip Point (Clallam Bay), but the energy is weak (38) and the conditions are poor. Tuesday afternoon the wind swings WNW at 12 mph and it’s cross-on, so don’t even bother. Wednesday through to the end of the month are all similar – flat or tiny, with onshore or cross-onshore winds, and poor surf conditions. Saturday the 29th has a glassy morning with 2 ft of W swell, but the period is a short 6 seconds and the energy is only 27 – it’s just not enough to get excited about.
Sunday the 30th is a little better with 2 ft W swell and a 7-second period, but still poor surf conditions. The same story continues through Monday the 31st, with a tiny 1 ft to 1 ft WNW swell and a long period of 11 seconds on Monday afternoon, but the energy is low (40) and it’s cross-on. The 1st of September is flat and glassy – a total blank.
Now, here’s where things get slightly interesting. On the morning of Wednesday the 2nd of September, we get a 2 ft W swell with a 9-second period and the combined energy climbs to 76. The wind is a glassy 3 mph from the north, so the surface will be clean. It’s surfable, but very ordinary. This is the first real chance to get wet, but keep expectations low. That afternoon, the wind swings NW at 9 mph and conditions go poor again.
There’s another gap on the 3rd and 4th of September – mostly flat or tiny, with clean winds but no swell to speak of.
The real standout comes on Saturday the 5th of September. The morning brings a 2 ft WNW swell, period 10 seconds, and energy reading 102 (moderate). The wind is a clean offshore from the east at 9 mph, so the surface will be clean and lined up. By the afternoon, the swell period stretches to 12 seconds, energy jumps to 145, and the wind is still a light offshore from the east at 6 mph. That’s going to be the best surf of the whole window – small, but clean, and the direction is nearly perfect for Slip Point which likes WNW swell. The morning of Sunday the 6th of September is similar with 2 ft WNW, 11-second period, 119 energy, and clean offshore winds. Sunday afternoon stays glassy with the same swell size. After that, it fades out again on the 7th and 8th, with a slight bump to 3 ft on the 8th but poor onshore winds ruin it.
Water temperature? We don’t have a specific number here, but the anomaly is normal for this time of year, so don’t expect anything out of the ordinary.
To wrap it up: if you’re desperate for a paddle, the morning of the 2nd of September is your first chance, but it’s ordinary. The best surf of the whole outlook is the morning of the 5th of September through the 6th – small, clean, and offshore. Everything else is a write-off.
Rusty.
