The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for the next couple of weeks at Trestles.
Right off the bat, the standout session is gonna be this Sunday morning, September 6th. We've got a solid pulse of South swell coming in at 5.9ft with a nice 14-second period pushing some serious energy through – we're talking 1227 (moderate to strong energy). The water's sitting at 73.6°, which is a good 5.8° warmer than normal for this time of year, so it's feeling like a bathtub out there. The wind is blowing from the North at 9 mph, giving us a clean cross-off that'll keep the faces smooth. This is prime territory for the experienced crew on the reef and point set-up. If you're an advanced surfer, this is the one to circle. The break is very consistent and always has a crowd, so expect company, but the quality will be worth the paddle battle.
That Sunday afternoon holds up nicely too – same day, September 6th, with the swell dropping a touch to 4.9ft, still from the South, period at 13 seconds, and the energy at 1275 (still strong). The wind shifts to a clean offshore from the NE at 9 mph. This is gonna be clean, lined-up, and perfect for the afternoon session after the morning rush.
Now, Monday the 7th is where things start to turn. The morning has 5.9ft of SSW swell, but the wind goes cross-on from the WNW at 9 mph, putting a bit of a chop on it. The afternoon gets worse with the wind picking up to 16 mph and going full cross-shore. The energy is dropping, and the quality is taking a hit. From here on out, it's a slow fade.
Tuesday the 8th through the rest of the week and into the second week is pretty grim. Swell sizes drop, periods get weird, and the wind stays onshore or cross-on for most of it. There's a brief moment on Wednesday the 9th with a 2.0ft swell from the SW, but it's a 16-second period and onshore wind, so it's a flat, crumbly mess. The energy readings are down in the hundreds (weak to moderate), and the scores reflect it – not much to get excited about.
From Monday the 14th all the way through to the end of the forecast on September 21st, we're looking at tiny waves. Mostly under 3ft, long periods up to 20 seconds, but with onshore or cross-on breezes. There are a few marginal moments on the 16th and the 21st with a bit of a bump in energy (500 and 647 respectively), but the wind isn't playing ball. The swell direction from the SSW or SW isn't ideal for this spot, which loves a good West swell. The whole second week is a write-off for quality surfing. You might find a knee-high ripple, but nothing worth paddling out for.
So, the short version: Sunday the 6th is your day. Get on it. After that, it's a long, flat, choppy wait.
