The Lowdown

Alright folks, Rusty here. Let’s break down what’s ahead.

We’re looking at Trestles (Uppers) – a reef and point setup that’s very consistent and exposed for west swell. The water’s a balmy 71°, which is much warmer than usual for this time of year, so you can leave the wetsuit at home.

The first few days are a bit of a write-off. Thursday the 16th through Saturday the 18th are small and messy with cross-onshore winds, so don’t get your hopes up. The combined swell energy is weak to moderate at best, with readings from 240 to 487. It’s just not worth paddling out for.

Things start to get a little more interesting from Sunday the 19th. The swell picks up to 4ft on Sunday morning from the S, and by the afternoon it’s 4ft with a 12-second period, and the combined energy jumps to 1023. That’s moderate energy, but it’s straight onshore wind, so it’ll be a bit lumpy. The surface won’t be inspired.

The standout window is shaping up around Wednesday the 22nd afternoon through Thursday the 23rd. On Wednesday afternoon, we’ve got 5ft from the S at 15 seconds, with combined energy hitting 1243 – that’s solid moderate energy. But the wind is a moderate cross-onshore, so it’ll be choppy. The real highlight is Thursday the 23rd: morning and afternoon both see 6 to 6ft of S swell, with light onshore breezes keeping the surface clean. The energy is strong at 1525 and 1368. That’s the best run of the forecast. The swell is getting up there, so it’s not for beginners, but for the experienced crew, this is where it’s at. The wind is light and the waves will have some real push.

Beyond that, the following week from Friday the 24th into the end of the month holds surf in the 4 to 6ft range, mostly from the S and SSW, with periods improving to 18-19 seconds by the 26th and 27th. That long period will bring nice shape but can make the sets a bit lully. The wind stays light and mostly onshore or cross-onshore, so the quality will be okay but not epic. The energy readings stay in the moderate to strong bracket, mostly in the 1200-1600 range, so there’s always something to ride – just nothing that jumps out as a true standout after the 23rd.
