The Lowdown
Alright, Rusty here again. Let’s break down the same outlook, but in the units we use down at the shop.
The next couple of weeks at Slip Point are looking tough. Sunday the 19th kicks things off with zero surf and zero energy. The water is a bone-chilling 52°, which is 6° colder than average for this time of year – that’s a real shock to the system. Then we get a long, dry run. From Monday the 20th all the way to Saturday the 2nd of August, it’s either flat or just tiny, wind-blown junk. You’ll see knee-high waves of 2 to 3 feet on a few days, but the wind is onshore or cross-onshore, making it a choppy, lumpy mess. The energy readings are mostly in the weak to moderate range, topping out at 103 on the 23rd, but that comes with a stiff onshore breeze, so it’s no good.
The one bright spot, and I mean the only one, is Monday morning the 3rd of August. We’ve got a clean 4-foot swell from the west, with a 9-second period. The wind is a light, cross-offshore breeze from the east, which will groom the waves perfectly. The combined energy hits a solid 186 – that’s the best we’ll see. This is the window to be in the water. The afternoon gets a little bigger, to 4 feet, but the wind switches to a cross-on shore from the NNW, so it’ll lose that clean face. This is a point break that’s fairly exposed to the WNW, so that morning window is our only real shot. Crowds are listed as “sometimes” here, so you might have company, but it won’t be a zoo.
It’s a long wait, but that Monday morning on the 3rd of August is worth holding out for.
Rusty.
