The Lowdown
Alright folks, it’s Rusty here, and I’ve stared at the charts for our stretch of coast. Let’s be real from the get-go: the next week and a half is looking pretty grim. There’s a long, quiet gap ahead.
We’re looking at Trestles (Lowers), and for the first week, starting Sunday the 2nd of August, it’s pretty much a write-off. The swell is tiny, barely pushing 2ft to 2ft, and coming from the SW. The combined wave energy is weak, maxing out in the low 200’s (186 up to 213). The water is a bucket-list warm 76°F, which is much warmer than normal for this time of year, but you'll be sitting on a flat ocean. The wind is light onshore or cross-onshore, not doing the waves any favors. The reports are all "poor surf conditions." It’s flat, folks. There’s nothing to ride.
This quiet spell stretches right through the second week. We’re talking about a solid stretch of days with no real surfable options. Through the 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th, and 13th of August, it’s the same story. The swell heights are 1ft to 3ft, the energy stays low, and the wind is mostly light and onshore. It’s a long, flat run.
Now, there is a little flicker of hope late in the forecast. On the 14th of August, a Friday, we finally see the swell push up to 4ft from the SW. The combined energy jumps to 756 – a moderate level. The period is a solid 17 seconds, so it’s a groundswell, which is a plus. But the wind is a light cross-onshore, and the forecast is still calling it "marginal." It’s not a standout, but it’s the best we’ve got.
The 15th of August, Saturday, holds that same 4ft SW swell with 16-second periods, keeping the energy in the 600s (626 to 642). Again, the wind is a cross-onshore, making it a bit choppy. It’s still in the "marginal" category.
The 16th and 17th drop back off again, with the swell fading to 3ft to 3ft.
So, to be honest, there’s no true standout session in this 16-day run. The only time you might get a wave is around the 14th and 15th of August, but it’s not going to be clean. The wind is never truly offshore for Trestles – it’s always on, cross-on, or at best light. The break is very consistent, so when it goes flat, it’s a bummer. For now, save your energy. The forecasts can change, but right now, it’s a long wait.
Rusty.
