The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Trestles (Uppers).
Right off the bat, it’s a bit of a slow start. The first few days are looking pretty average. Wednesday the 22nd and Thursday the 23rd are a write-off, to be honest. The wind is all cross-onshore and the swell is messy. It’s just not worth paddling out for. We’ll be sitting on the beach watching the bumpy lines roll through. The combined energy is moderate (441-627) but the wind just kills it.
Then Friday the 24th and Saturday the 25th offer a glimmer. The swell comes from the SSW/SW, and while the heights are small (2ft to 3ft), we get a very long period groundswell of 21-24 seconds. That means those waves will have some real shape and push, especially for a point and reef like Trestles. The wind is light, so it’ll be glassy with small wind ripples. The combined energy is moderate (827-970). It’s not going to be huge, but for a clean, long-period wave, it’s a fun little window. Saturday morning looks the pick of this early stretch.
The middle of the week, from Sunday the 26th through Tuesday the 28th, sees a bit more size, with the swell hitting 4ft to 4ft from the SSW/SW, with periods around 17-19 seconds. The combined energy is strong (1013-1050). The issue is the wind – it’s either cross-on or light and variable. It’s marginal, but there could be a few windows. Monday the 27th afternoon has the best score of this stretch, with light winds and a 4ft SSW swell.
Now, the real stand-out in this whole 16-day window is Saturday the 1st of August. This is the one to circle. The swell jumps up to 6ft to 6ft from the S, with a period of 13 seconds. The combined energy is strong (1161-1390). That S swell is a good direction for Trestles, and over 5ft, it’s going to be solid. The wind is a cross-onshore at 9 mph, so it’ll be a bit choppy, but the size and power will make up for it. This is big enough for experienced surfers, but beginners might find it a bit much. After that, the swell drops off quickly through the second week, with small, clean conditions from the 2nd of August, but nothing to get excited about.
The water temp is about average for the time of year, so no need for a thick suit.
Best Bet: Get out there on Saturday the 1st of August. That S swell (6ft-6ft) with strong energy (1390) is the biggest and best wave of the whole period. Just be prepared for a bit of a bumpy surface from the cross-onshore breeze.
Rusty out.
