The Lowdown
Alright, folks, Rusty here. Let’s break down what’s cookin’ for the next 16 days.
We’re lookin’ at a slow start, but the first real chance to get wet hits Saturday, September 6th, with some size. The real standout in this whole window is Trestles (Uppers). It’s a reef and point, super consistent, and open to the swell. Water temp is 74°, which is a full 7° warmer than usual for this time of year – that’s strange, so you’ll be in some warm water.
On Saturday morning, September 6th, we’ve got a clean 6ft SSW swell rollin’ in with a 14-second period, and a north wind holdin’ it cross-offshore. That’s gonna make for some proper, well-shaped lines. The combined energy is strong at 1432, so there’s plenty of juice. This is for advanced surfers – at 6ft with that long period, it’s a powerful wave, not for beginners. The swell direction (SSW) is a bit off the ideal (W), but it’ll still wrap in nicely. Crowds are always a problem here, so expect company.
Saturday afternoon sees a drop to 5ft from the S, still a 13-second period, but the wind goes light cross-shore from the NW, keepin’ it rideable. The energy is still moderate at 1263.
Sunday, September 7th, morning is a bit more exposed with a WNW cross-on breeze at 9 mph, makin’ the 6ft SSW swell a little choppy. The combined energy is moderate at 1228. Afternoon gets choppier with a moderate breeze, so not the best session.
The surf then fades. By Monday, September 8th, we’re down to 5ft and smaller, with weaker energy and a cross-onshore breeze. The rest of the week into the second week looks poor. There’s a spell of tiny, weak swell from the SW with very long periods (16-18 seconds) but barely any size – 2ft to 2ft. The energy is low (under 500), and the wind is mostly onshore or cross-onshore. Not worth paddlin’ out for.
We do see a little pulse on September 19th, with a 5ft W swell at an 8-second period, but it’s short-period windswell and the wind is cross-onshore. The energy is moderate at 759, but with the short period and poor wind, it’s not a standout. After that, it fades again into the 20th.
So, the call is clear: hit Trestles (Uppers) on Saturday morning, September 6th, for the best, cleanest, most powerful waves of the whole period. After that, it’s a long wait.
Rusty.
