The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
It's a quiet stretch for Trestles (Uppers) for most of the run. The early part of the outlook is a bit of a write-off, with a whole lot of days where the conditions are just too marginal or poor to get excited about. Wave energy is on the lower side or moderate at best, with combined energy values mostly in the 200 to 450 range, and the wind is cross-onshore or onshore more often than not. The water temp is about average for the time of year, so wetsuit choice is standard.
It's not until the very end of the 16-day window, around the 29th of August and into the 30th, that we see something that might be worth a look. The 29th of August morning has a long-period groundswell coming from the SSW at 3 ft, with a period of 17 seconds. The combined energy is up to 647 (moderate) and the wind is light and onshore. That long period will give the point some nice shape, but it could also make it a bit fat. The crowd is always a factor at Uppers, so expect company. The afternoon of the 29th pushes the swell to 4 ft from the SSW, period 16 seconds, and energy at 711 (moderate), but the wind is a light cross-onshore, which will bring some small ripples. The 30th of August morning holds at 3 ft from the SSW, with a light cross-onshore breeze, so it's still a possibility, but again, it's marginal.
Looking further into the first week of September, we see a similar pattern of small, weak swells and cross-onshore wind. There's a 5 ft WNW swell chopping through on the 31st of August afternoon, but with a period of just 8 seconds and a gentle cross-onshore breeze, it's going to be a messy, short-period windswell. Not ideal for a point like Uppers.
So, if you've got a paddle-hungry crew, the standout is the 29th of August morning. It's not perfect, but it's the best of a pretty average bunch. The long-period SSW groundswell will bring some energy, but the onshore wind will keep it from being a glassy classic. For the rest of the run, the pickings are slim.
Rusty.
