Alright, Rusty here. Let’s talk about what we’ve got on the table for the next couple of weeks.
First up, we’re looking at Trestles (Uppers). It’s a reef and point setup, very consistent, and it’s exposed to the swell. The water temp is sitting at 69°F with an anomaly of about 3°F above normal, so it’s a touch warmer than usual for this time of year – not a crazy shift, but you’ll feel it. Don’t expect much for the start though. Saturday the 4th through to Friday the 11th is pretty much a write-off: marginal to poor surf, small SSW swell around 3ft to 4ft, and mostly cross-onshore breezes keeping things choppy and messy. The combined wave energy floats between 393 and 920 – moderate energy, but the quality just isn’t there because of wind and poor conditions.
There’s a long gap here with no real recommendation for well over a week. The real standout window pops up later. Check this: Saturday the 18th morning, we start to see a shift – slight offshore in the a.m. with a light cross-off wind from the North in the afternoon. Swell is 3ft from the southwest, at a nice 17 seconds period – that’s a proper long-period groundswell, bringing shape and punch. The combined swell energy sits around 482 to 488, and for the first time in a long while, the forecast calls for clean waves. The wind is light and glassy/offshore, so the lines should be clean and fun on the point. This is the best on offer. Don’t get too excited too early; it’s still a bit far out, so treat it as promising but not locked in just yet. After that, Sunday the 19th fades back into cross-onshore chop, so that Saturday window is your best bet. It’s likely to be busy – crowds are listed as always here, so I’d plan for a dawny or late session.
Right now, for the next couple of days, the water temp at Trestles (Uppers) is about 69°F, which is a touch warmer than normal for this time of year – you won’t need a thick suit. Through the middle of next week, it’s a flat, blown-out slog. No real hope until that Saturday the 18th.
Stay sharp, and keep an eye on that Saturday the 18th window. Might be worth burning some fuel for.
