The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Trestles (Uppers). This is a reef and point break, very consistent, and it’s exposed to the west swell. It’s an advanced spot and it’s always crowded, so expect company. The water temp is a warm 73°, which is way above average for this time of year – about 5° warmer than normal, so you can leave the thick suit at home.
Right now, we’ve got a slow start. For Tuesday the 25th, it’s marginal at best. Morning sees a mere 2ft SW groundswell with a super long 16-second period and combined energy of 358 (moderate). The wind is light onshore, so it’s not doing us any favours. This is really for the die-hards only.
Wednesday the 26th offers a slight bump. The morning swell picks up to 5ft from the south with a 12-second period and moderate energy (880). Wind is still light and onshore, keeping things a bit lumpy. Still in the marginal zone.
We roll into Thursday the 27th with a 4ft S swell, 12-second period, energy dropping to 667 (moderate). Wind is light onshore again. Not great, not terrible, just… there.
Friday the 28th is a step back with morning swell dropping to 3ft at a long 16 seconds from the SSW, but the wind goes cross-onshore with a light breeze (535 energy). It’s cleanish but small.
Saturday the 29th is where it gets interesting. The morning sees 3ft SSW groundswell with a very long 17-second period, energy at 710 (moderate). The wind is a light cross-onshore. This long-period groundswell will be breaking a bit straight on the beach but at a point like Uppers, it will wrap in nicely. The afternoon builds to 4ft with 16 seconds and energy at 825 (moderate). This is the best-looking window of the first week – clean enough, with some real push from that long-period energy.
Sunday the 30th holds similar size around 3 to 4ft, but the wind picks up to a gentle cross-onshore on Sunday morning, so it'll be a bit choppier. Afternoon wind backs off again.
There’s a real dry spell slapping us from Monday the 31st all the way through Wednesday the 9th of September. The swell stays tiny, mostly between 2ft and 4ft, with a few days of poor surf conditions and light onshore or cross-onshore winds. The combined energy dips as low as 168 (weak) on the 7th. It’s a real bummer stretch. The morning of the 3rd has a whisper of a long-period 18-second SSW swell at just 2ft, but it’s still marginal.
The standout of the whole 16 days is definitely Saturday the 29th. You get that 4ft SSW groundswell with a 16-second period that will wrap into Uppers perfectly, and the wind is light. It won’t be huge, but it’ll be clean and fun. After that, it’s a long wait for the next pulse of energy on the 9th of September, but that’s still small and uncertain this far out.
Stay patient, grab a log for the small stuff, and keep an eye on Saturday the 29th.
Rusty.
