Alright folks, Rusty here. Let's have a look at what Trestles (Uppers) has in store for us over the next couple of weeks.
Right off the bat, we're looking at a pretty grim stretch. The water is sitting at 68°, which is a touch warmer than normal for this time of year, but that's about the only positive. For the first few days, we've got a long-period SSW groundswell pushing in, and the combined energy is moderate (450), but the wind is all wrong. It's cross-on from the WSW, and the result is poor surf. That's a tough start.
Things stay marginal through the first week. The swell hangs around in the 2ft to 4ft range from the SSW, with those long periods up to 20 seconds, so the energy is moderate to strong (873). The problem is that the wind only switches to true offshore on the morning of Tuesday the 7th, but the conditions are still described as questionable. The pattern is a lot of light onshore or cross-onshore winds, keeping the surface bumpy. Honestly, the best window in this whole first week is the Saturday afternoon of the 11th. It goes glassy, dead calm, with a 3ft SSW swell. That's a small window of clean surf, but it's a small wave.
That gives way to a long, dry spell. From Sunday the 12th all the way through to Friday the 17th of July, the surf drops right off. We're looking at swell heights under 2ft, combined energy dropping to weak (177), and the winds are either light onshore or cross-onshore. It's a proper lull, and not worth paddling out for.
The 16-day window does have a late pulse. On the 18th of July, a Saturday, we get a new SSW swell hitting. The morning of the 18th shows a 3ft swell with a 17-second period and a moderate surge of energy (694), with a light onshore breeze. It's marginal, but it's a spark. The real standout, though, is the 20th of July. The afternoon of that Monday shows a 5ft SSW swell, with a 15-second period, and combined energy hitting 999. That's strong. The wind is light cross-on, so it's not perfect, but it's the biggest, most powerful swell of the whole outlook. It's a late call, so treat it as promising but not guaranteed, but if it comes together, that afternoon will be the time to be at Uppers.
Right now, though, I’d mark that Saturday afternoon the 11th for a glassy session, and keep an eye on the 20th for the real size.
Rusty.
