The Lowdown
G’day, Rusty here. Let’s talk about what’s in store for Trestles (Uppers) over the next two weeks.
Things are flat to start. The first real surf shows up on Sunday the 6th. Before that, Thursday the 4th and Friday the 5th have small, cross-onshore bump and the water is 75° – that’s much warmer than average for this time of year. A nice swim, but not much for surfing.
Sunday the 6th is the one to circle. Offshore NNE wind at 6 mph will have Trestles slick and clean. Swell hits 6 ft from the S with a 14-second period – that’s real groundswell power (combined energy of all swells directed here is 1402). Long period waves love this reef and point, and you’ll get long, smooth lines. Water is still much warmer than usual. It’s advanced-level size, so only for the experienced, and you’ll have company – it’s always busy.
Monday the 7th keeps size around 7 ft to 7 ft from the SSW, but the wind swings WNW and gets cross-onshore, turning it choppier. Still surfable, but not as good. From Tuesday the 8th onward, the swell drops and the wind stays cross-onshore or cross-shore most days, and we hit a long stretch of poor to marginal surf that goes well into the second week.
There’s a small bump on Friday the 18th afternoon – 5 ft from the W but with a short 8-second period and cross-onshore wind. That’s windswell, combined energy of 893. Choppy and messy. Saturday the 19th morning has 3 ft from the SW at 18 seconds, but again light cross-onshore – clean but tiny.
So the clear best is Sunday the 6th. Offshore wind, solid south groundswell, long period, great setup. After that, it’s a quiet spell for over a week. Trestles goes flat sometimes, but forecasts can turn – it usually doesn’t stay poor forever around here.
Rusty.
