The Lowdown

Hey folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty flat and quiet around Trestles (Lowers). We’ve got a bit of a lull on our hands, but let’s see what’s actually worth paddling out for.

The action kicks off Wednesday morning, July 29th, with a small, long-period groundswell filling in. We’re looking at a clean 4 ft from the SSW with a 16-second period, which is a proper long-period groundswell. The winds are light and onshore, so it’s not going to be glassy, but the water is a toasty 73°, which is much warmer than normal for this time of year. The combined energy is moderate at 870, so there’s some push but it’s not a powerhouse. The same day afternoon sees a slight bump to 4 ft from the same direction, with the energy cranking up to a moderate 1016. The wind swings to a light WSW, still onshore, so it’ll be a bit bumpy. This is a reef-and-beach setup, so the long period might make it a bit straight at the beach section, but the points could have some shape.

Thursday the 30th stays small, with morning coming in at 3 ft from the SSW, 15-second period, and a light cross-onshore wind. The energy is moderate at 808. The afternoon sees a little more size at 5 ft from the S, but the period drops to 14 seconds, and the wind is still light cross-onshore. The conditions are described as “marginal” with small wind ripples, so it’s not going to be a clean session by any stretch.

Friday the 31st through the whole first week of August is a real struggle. Swell drops to 2 ft to 3 ft, periods are short to moderate, and the winds are either onshore or cross-onshore with a gentle breeze, making things choppy. The combined energy drops into the 100-300 range, which is weak. By the weekend, August 1st and 2nd, we’re looking at 2 ft to 3 ft from the SSW or SW, with a 13-14 second period, but the wind is messing up any chance of a clean wave. The breaks are rated as “poor” or “marginal,” and honestly, there’s nothing to get excited about.

The entire second week, from August 4th through the 13th, is a flat spell. Swell heights are consistently 1 ft to 3 ft from the SW or SSW. The periods are all over the place, from 13 seconds up to a very long 20 seconds on August 10th afternoon, but with such tiny wave heights, that long period just means a long wait between ankle-biters. The combined energy is weak, mostly below 400, and the winds are light and onshore or cross-onshore. The conditions are consistently described as “poor” or “marginal.” For a spot that’s “very consistent,” this blank run is a bit of a bummer, but it happens.

The only real standout, and I’m using that term loosely, is the first Wednesday and Thursday, July 29th and 30th. The 5 ft afternoon on Thursday from the S is the biggest we’ll see, but the cross-onshore wind and the “marginal” surf forecast mean it’s not going to be great. If you’re desperate, the morning of the 29th with the 4 ft groundswell and the 16-second period might offer a few clean lines before the wind picks up, but you’ll need to pick your tide and be patient. The SSW swell direction is right on the optimum for Trestles, but the size and wind just aren’t cooperating.

Rusty.
