The Lowdown
Alright folks, Rusty here, looking at the stretch ahead for Trestles (Uppers). Gotta be straight with you – this outlook is a tough one. For the next week and a half, we’re looking at a lot of small, weak surf and iffy conditions. It’s not going to be flat, but it's going to be a grind.
The first few days are pretty much a write-off. We’ve got some small swells bumping in, but the energy is weak (116-438), and the wind is mostly onshore or cross-onshore, messing up any potential. The swell is coming from the southwest, and it’s just not lining up for this spot at all. You’d be fighting for scraps and it wouldn’t be worth the paddle.
We finally see a slight pulse of energy around Friday the 14th, with the swell picking up a touch and the energy readings climbing (756-894). Still, the forecast isn't great, just marginal. The wind is a mix of light onshore and some cross-on conditions. It’s better than nothing, but don't expect miracles.
The most promising window looks to be the morning of Sunday the 16th. Swell is around 3ft from the SSW, and the winds are light and onshore early, but glassy enough to keep things clean-ish before the afternoon breeze kicks in. Energy is a moderate 536. The break is very consistent, so there will be waves, but with those light onshore winds, it'll never be perfect. Crowds are always an issue here, so you’ll have company.
As we get into the second week, the energy drops again and the winds start to get more cross-on and choppy. There’s a glimmer of something on Friday the 21st – the period drops to 8 seconds, which is junk, and the wind is still on it. Honestly, that looks more like a kite-surfing day here than a surfing one.
The bottom line? Uppers is a world-class reef and point when it's on, but it's going to be a frustrating couple of weeks. The swell direction is just not working with the spot's optimum W direction. The water temp is about average for this time of year. For the standout, I’d have to say Sunday morning the 16th is your best shot for a clean-ish session, but keep expectations low. Long-range stuff later in the week suggests more energy, but it's promising and less certain. Hang tight, keep an eye on it, and maybe have a backup plan.
Rusty out.
