Table - best surf conditions forecast for Trestles (Lowers) over the next 16 days.
Alright, this is Rusty.
Let’s look at what’s happening at Trestles (Lowers) over the next 16 days. The first week is a slow grind, but there’s some promise if you’re willing to wait.
The water is sitting at about 68° right now, which is a touch warmer than normal for the time of year, so you’ll be comfortable in a spring suit.
Wednesday morning, July 8th, we start with a 4ft SSW swell. The period is a solid 16 seconds, which is proper groundswell, but the wind is a light onshore breeze, and the conditions are just marginal. The combined energy is 898 - moderate, but it’s not clean.
Thursday through to the end of the next week is pretty rough. The swell drops to 3ft or less, the wind stays cross-onshore or onshore, and the energy drops into the 200-400 range. The comment for most of these days is “poor surf conditions” or “marginal.” This stretch from Thursday July 9th through Friday July 17th is a total washout.
Now, here’s where it gets interesting. Saturday morning, July 18th, we see a glimmer of hope. The swell picks up to 3ft from the SW with an 18-second period. The wind is glassy – that’s the word. The combined energy jumps to 468. This is the first time the forecast says “expect good surf conditions.” It’s small, but it’ll be clean and fun on the longboard.
Then, Sunday July 19th is the big one. We’ve got a 5ft S swell with a 16-second period and a light cross-onshore breeze. The energy is a massive 1696, which is strong. The morning is the pick with a 3 mph offshore breeze. This is a proper swell, but at 5ft, it’s not for beginners. The long period from the south means it’ll be a bit walled up at the beach breaks, but Trestles is a reef and point setup, so it should handle it nicely. The afternoon drops to 5ft with a 14-second period and 1823 energy, still solid but the wind gets a little more cross-on.
Monday the 20th and Tuesday the 21st see the swell ease back into the 3ft to 4ft range with moderate energy, and the wind is light. Nothing special, but rideable.
The last real highlight is Thursday July 23rd afternoon. A 5ft S swell with a 16-second period and 1440 energy rolls in, with a light cross-onshore breeze. That’s a solid afternoon session if you can get out.
Overall, the best bet is the glassy morning of Saturday July 18th for a clean, small wave session, or the Sunday July 19th morning for a bigger, more powerful swell. The crowd situation at Trestles is always a factor, so expect company.
Rusty.
