Trestles (Lowers) Surf Forecast and Surf Report

Alright, folks, Rusty here. Let's talk about what's cookin'.

The first few days are a real dud. Saturday the 22nd through Sunday the 23rd, we're looking at tiny 2ft swell, with the wind blowing cross-on or onshore. The energy is weak (192 to 353), and the reports say it's poor. Not worth even taking the board off the roof. Monday the 24th and Tuesday the 25th are still marginal, with the swell barely scraping 2ft and the wind still cross-on. The energy is building a bit, but it's still not on.

Things start to look a little more interesting from Wednesday the 26th. The swell bumps up to 3ft in the morning, coming from the S with a period of 15 seconds – that's a proper long-period groundswell. The energy jumps to 710, which is moderate. The wind is light cross-on, so it's a bit bumpy but not terrible. By the afternoon, the swell pushes to 6ft, with a period of 15 seconds, and the energy hits 1310. That's a solid pulse. The wind is still cross-on and a bit stronger, so it'll be a bit choppy. This is the first window where it's worth a look, but the wind is a letdown.

Thursday the 27th is a mixed bag. The morning sees 5ft from the SSW with a period of 12 seconds. The wind is light and onshore, so it's clean but the energy is moderate (825). The afternoon drops to 4ft, still clean but the energy fades. It's a passable day, but not a standout.

Friday the 28th through to the end of the month, the swell drops back to small stuff, 2ft to 4ft, and the wind keeps switching between cross-on and onshore. The energy ranges from 290 to 869. Nothing to get excited about.

The first week of September offers a glimmer. On Wednesday the 2nd, the swell is 4ft from the W with a short period of 8 seconds. That's windswell, not groundswell, so the waves will be a bit mushy and close together. The wind is light and onshore, so it's clean. The energy is moderate (539). Not a classic Trestles day.

The real standout in this forecast is Friday the 4th of September. The morning sees a clean 3ft swell from the SSW, with a period of 18 seconds. That's a very long-period groundswell, packing a punch. The combined energy is 1004, which is strong. The wind is light and onshore, so the face will be glassy. This is the kind of day where Trestles (Lowers) can really shine. The swell direction is SSW, which is a bit off the optimum SW, but the quality of the swell and the clean conditions make it a top pick. The afternoon swells up to 4ft with a period of 17 seconds, and the energy jumps to 1200. The wind turns light cross-on, so it's still plenty rideable. This is the best bet on offer.

Saturday the 5th and Sunday the 6th of September continue the trend. Saturday morning is 4ft from the SSW, period 16 seconds, energy 1267, with clean onshore wind. The afternoon sees 4ft from the SSE, period 16 seconds, energy 1430. Sunday the 6th morning is 5ft from the S, period 15 seconds, energy 1355, with clean onshore wind. These are all solid, long-period groundswells, but the wind is consistently onshore, which will keep the surface bumpy. For a high-performance wave like Trestles, that's a caveat.

Overall, the best window is from Friday the 4th of September through the weekend. The swell is consistent, the period is long, and the energy is strong. The wind is the only doubt, but it's light. For a spot that's very consistent and exposed to the SW, this is a promising run. The water temperature is about average for the time of year, so no surprises there. Crowds are always a factor at Trestles, so expect company.

Rusty.
