The Lowdown
Alright folks, Rusty here. Let's have a look at what’s on the cards for the next couple of weeks around Trestles (Uppers). I gotta be straight with you – this is a bit of a quiet spell, and we're going to have to work for anything decent. The trade-off? When it does line up, this spot is a world-class reef and point, so we wait.
Right off the bat, the outlook is grim. We've got a long dry spell from now until about August 14th. There are days on end with barely a bump. The swell is tiny, often around 2 ft to 3 ft, coming from the SSW. The problem is the wind. It’s cross-on or onshore for most of this first week and a half, killing any chance of quality. The wave energy is weak to moderate at best – those readings in the 300s and 400s (combined energy) tell the story of a tired ocean. There’s nothing here worth paddling out for unless you’re desperate for a float.
We finally see a slight pulse of energy rolling in around the 15th of August. On Saturday morning, we’ve got some clouds, a light cross-on breeze from the SSW at 9 mph, and the swell starts to nudge up a bit more. By the afternoon, the clouds thicken, but the wind drops a little, and the swell hits about 4 ft. The combined energy jumps up into the 700s, which is moderate but still feels weak for Uppers. The swell period is a short 16 seconds for the size, so it won’t have much punch. It’s still marginal.
The one moment worth circling on your calendar is the 21st of August, Friday afternoon. This is the best on offer across the whole 16-day run. We get a slightly better mix with the swell from the S at 3 ft and a period of 15 seconds. The combined energy climbs to 578. But more importantly, the wind goes light and onshore from the SSW at 6 mph, so it’ll be clean with only a light bump. The score for that window is a 2 out of 10, which tells you all you need to know about the general state of the surf, but relatively speaking, this is the best session we’ve got. The swell direction from the S is a touch more favourable for Uppers, and the lighter wind will mean smoother faces.
Bottom line: if you live nearby and have a flexible schedule, maybe take a long lunch on the 21st for a few knee-to-waist high runners. Other than that, this is a two-week stretch that's mostly best spent tuning up your gear for the next real swell.
Rusty.
