The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
So, we’re talkin’ about Trestles (Uppers) , a classic reef and point break that’s wide open to a W swell. The water’s a balmy 71°F right now, which is a good 4°F warmer than average – feels like a warm bath, mate. The first few days are a bit of a tease. We’ve got some long-period groundswell rollin’ in, but the conditions are just holdin’ things back.
The first real glimmer is on Saturday, 25 July. The morning shows a 0.9m (about 3 ft) SSW swell with a very long 21 seconds between waves. The combined energy is moderate (916). The wind is light and onshore from the SW, which isn’t ideal, but it’s light enough that it might not ruin it completely. The tide is a bit questionable, though. Saturday afternoon is similar.
Sunday, 26 July is about the same story – 1.1m (4 ft) SW swell, long period, but still that light onshore breeze.
Things start to build from Monday, 27 July. The morning bumps up to 1.3m (4 ft) from the SSW, period at 18 seconds, and the combined energy jumps into strong territory (1144). The wind is a light cross-onshore, so it’s a little bumpy. The real building happens through the week, with Thursday, 30 July seeing the morning push 1.6m (5 ft) from the S and the afternoon hitting 2.0m (7 ft) from the S. That afternoon session has a solid 15-second period and strong energy (1700), with a light offshore breeze from the SW. Cleaner conditions. That’s your first standout window.
Friday, 31 July keeps the size up with 2.1m (7 ft) from the S in the morning, period 14 seconds, and very strong energy (1800). The wind is a light cross-onshore, so there’s a slight ripple. It’s a big swell, gettin’ into the expert-only zone for the bigger sets. The point break nature of Trestles (Uppers) will handle that long-period swell well, but it’s goin’ to be a handful.
Saturday, 1 August still has some size at 1.7m (6 ft) in the morning, but the period is droppin’ to 13 seconds, and the energy is fadin’. The wind is light and onshore. After that, it’s pretty much a fade-out. From Sunday, 2 August onwards, the swell drops below 1m (3 ft), the energy gets weak (299 and lower), and conditions are described as poor. We’re lookin’ at a solid week of flat, small waves from 2 August to about 9 August. The size barely gets above 0.7m (2 ft), and the energy is weak. One tiny glimmer on Sunday, 9 August with a 0.7m (2 ft) SSW swell and a 17-second period, but it’s marginal.
So, the pick of the bunch is Thursday, 30 July afternoon and Friday, 31 July morning. That’s where you’ll find the biggest, most powerful swell with clean-ish winds. The rest of the first week is buildin’ but not quite clean. The second week is a write-off for any decent surf.
Rusty.
