Table - best surf conditions forecast for Trestles (Uppers) over the next 16 days.
Alright folks, Rusty here. Let’s take a look at the next stretch of days for Trestles (Uppers). It’s a reef and point setup, very consistent, and it’s exposed to the west swell. The water temp is about average for this time of year, nothing out of the ordinary.
Right off the bat, we’ve got a dry spell ahead. The first few days from Monday the 13th through to around Wednesday the 15th offer nothing worth paddling out for. The combination of small swell and onshore winds just isn't there. We’re looking at a blank run of about three days with no real surf on offer.
It’s not until Saturday the 18th that we start to see a flicker of life, but it’s still marginal. The combined swell energy is creeping up, reaching 531 on Saturday morning, but it’s a cross-onshore wind and the conditions are just not clean. That theme holds through Sunday the 19th and into Monday the 20th. The swell is there, but the wind is a buzzkill, keeping things choppy and messy.
Now, if you’re patient, the first real standout window appears on Wednesday the 22nd. On Wednesday afternoon, the wind flips to a light onshore from the SW at only 3 mph, almost glassy. The swell pushes up to 4 ft from the S with a period of 15 seconds – that’s a solid groundswell. The combined energy jumps to 1021, a moderate pulse. It’s still “marginal” in the files, but this is the best we’ll see for a while. The conditions could be clean enough for a few fun ones.
The next day, Thursday the 23rd, sees the swell peak at 6 ft from the S, but the period drops to 14 seconds. That size is getting into the “too big for beginners” territory, but it’s not a beast. The combined energy hits 1145, which is a solid moderate pulse. The wind is onshore/light in the morning, with a WSW breeze at 6 mph. It’s not ideal, but it’s the biggest swell of the run. Expect some lumpy, powerful waves.
After that, Friday the 24th and Saturday the 25th still have energy around 5 ft to 5 ft from the S/SSW, but the wind continues to be a cross-onshore factor. The period drops to 12-13 seconds, so it’s shorter period, more wind-affected surf. The best wave quality might be early morning when the wind is lightest.
The tail end of the 16-day window, from Sunday the 26th into Tuesday the 28th, sees the swell drop back down to the 2 ft to 3 ft range. The period is long again, 16-19 seconds, but the swell is just too small to make much of it, especially with cross-onshore winds. It’s going to be a quiet finish.
So, to boil it down: the standout days are Wednesday the 22nd afternoon for the cleanest conditions, and Thursday the 23rd for the biggest, most powerful swell. Both are worth a look if you’re keen. The rest is a bit of a wait.
Rusty out.
