Table - best surf conditions forecast for Trestles (Uppers) over the next 16 days.
Alright folks, Rusty here. Let’s get real about what we’ve got coming down the line for the next couple of weeks.
Right off the bat, I gotta say, it’s a bit of a slow grind for a while. The start of the period is looking pretty average. Trestles (Uppers) is our only option on the menu, and for the first week and a half, it’s just not happening. The swell is tiny, mostly between 1 ft and 3 ft, with a long 15 to 18 second period from the SSW and SW. The problem is the wind is cross-onshore or onshore, making it choppy and messy. The water temp is sitting at 67°, which is pretty much average for this time of year, no surprise there. The combined energy is generally weak, bouncing around a few hundred – nothing to write home about. We’re looking at a lot of days where the score is a zero or a one, with comments like "poor surf conditions" or "marginal surf forecast." Honestly, from Friday the 10th right through to about Tuesday the 21st, it’s a long patch of flatness. You’d be hard-pressed to find a decent wave.
Now, there’s a little flicker of hope around Monday the 20th and Tuesday the 21st. The swell is still small, around 3 ft from the SSW with a 15-16 second period, but the wind is looking like it might go offshore or very light. The combined energy climbs a bit, hitting 740 on Monday afternoon. The scores only hit a 2, but with offshore wind, that tiny swell might clean up and offer a few little runners. It’s not a standout by any stretch, just the best of a bad bunch.
But here’s where it gets interesting. The real talking point, the one to circle on your calendar, is Saturday the 25th. We see a solid increase in swell size and energy. Saturday morning, the swell jumps to 4 ft from the S with a 16-second period, and the combined energy rockets up to 946 – that’s moderate to strong wave energy. The wind is looking light and offshore from the WSW, which means clean, lined-up waves. By the afternoon, the swell is up to 7 ft from the S with a 15-second period, and the energy is at a whopping 1993. That is a serious bump in energy. This is a strong groundswell, and with an offshore wind, Trestles (Uppers) could be cooking. That size is getting into expert territory, especially for the afternoon. The crowd factor is "always" at Uppers, so expect a full house, but when it’s this good, it’s worth the paddle. This is the one to aim for, but remember, it’s over a week out, so keep an eye on it.
So, the story is: a long, flat start, a tiny mid-period window that’s just okay, and then a potential standout at the very end on Saturday the 25th. Hang in there, get your gear ready for that final weekend.
Rusty.
