The Lowdown
Alright, Rusty here. Let’s talk about the stretch ahead for Chadbourne Gulch.
It’s a tricky start for the next couple of weeks. We’ve got a very long-period groundswell rolling in from the southwest, but the problem is the wind. For the first several days, there’s a persistent cross-onshore breeze that’s going to keep things choppy and messy. The water’s sitting at 59°, which is a touch warmer than average for this time of year, but that won’t make up for the lumpy conditions. The combined wave energy is moderate to strong (1214), but it’s just not coming together cleanly for a good paddle session.
The first real window you’d want to look at is Tuesday, August 4th. The wind drops right out in the afternoon, going glassy. The swell is a solid 6ft from the northwest, with a period of 8 seconds. That’s a short-period windswell, but with the clean, glassy surface, it’s going to be your best bet for something fun and rideable. This is the standout. Expect some fun, clean lines, though it’s not a groundswell, so don’t expect massive power. The energy is moderate (585).
The next day, Wednesday, August 5th, is almost a repeat. The afternoon goes glassy again, with a 6ft northwesterly swell at 9 seconds. It’s a touch smaller, but still clean and very surfable. This is a solid second option.
After that, the swell builds. By Saturday, August 9th, we’re looking at 8ft from the northwest, but the wind stays cross-onshore or onshore, so it’s going to be a bit of a battle. The real beast shows up on Monday, August 10th. The swell hits 10ft, with very strong wave energy (3073). The wind is favorable, but the size is sneaker – that’s expert-only territory. For the average surfer, those big days are more of a spectacle than a session.
So, here’s the takeaway: the first week is a write-off for clean surf. The second week has a couple of standout days, particularly Tuesday, August 4th and Wednesday, August 5th in the afternoons, when the glass-off hits. That’s the time to be in the water.
Rusty.
