The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’re looking at a bit of a mixed bag for Trestles (Uppers) over the next fortnight. The good news is there’s a window of solid, rideable swell coming through, but it’s bracketed by some pretty flat spells. The water is running at 71°—that’s much warmer than normal for this time of year, so you can leave the thick rubber at home.
The first sniff of decent surf kicks off Sunday morning, July 26th. We’ve got a clean 3 ft SSW groundswell rolling in with a long 19-second period and a light onshore breeze. The energy is moderate (863). It’s not huge, but that long period will wrap into the point nicely. Keep an eye on the tide, though—conditions are a bit questionable. Monday the 27th is a touch better, with the swell bumping up to 4 ft from the SSW, period still a solid 18 seconds, and the combined energy building into strong territory (1126). Winds are light and onshore, keeping things fairly clean. This is a good time to be out.
The standout of the whole run looks like Thursday, July 30th, and Friday, July 31st. We’re seeing a pulse of 6 ft to 6 ft swell from the S, with a period around 14 seconds. That’s a solid, powerful groundswell, and the energy is very strong (1366 for both Thursday arvo and Friday morning). The wind is light and onshore, which is a major positive—clean conditions for a point break like this. This is the best on offer. It’s not monstrous, but it’s a proper, rippable size for the advanced crew. Beginners might find it a bit much pushing over 5 ft.
After that, things wind down quickly. By Sunday, August 2nd, the swell drops to 3 ft and the energy is weak (228). From there, it’s a long, flat stretch. From Monday, August 3rd, right through to Monday, August 10th, the surf is mostly poor. You’re looking at dribbly 1 ft to 3 ft swells, mostly with cross-onshore winds, and the combined energy barely cracks the 200s. There’s a brief flicker on Friday, August 7th, with a 3 ft SSW swell and a long 19-second period, but the cross-onshore wind will chop it up. Honestly, it’s a pretty blank run for the second week. Keep your hopes up, though—Trestles is consistent, and the forecasts can change.
So, the call is simple: get it this week. Thursday the 30th and Friday the 31st are the days to circle. The S swell, light winds, and classic Uppers setup will be firing. The rest of the run is a write-off until something new shows up.
Rusty.
