The Lowdown
Alright, Rusty here. Let's talk about the next 16 days for Surfside Jetty.
Gonna be real with you, it's a tough stretch. The water is sitting at 70°, which is a touch warmer than normal for this time of year, so that's a tiny win. But that's about where the good news ends. The whole first week and a half is a write-off. We're looking at a solid 10 days of "poor surf conditions" with waves barely cracking 3 ft, and the energy is weak. The wind is mostly onshore or cross-onshore, so it's going to be bumpy and messy. The swell is coming from the SSW, which isn't ideal for this spot that prefers a more westerly direction. It's a pretty bleak run.
Now, there is a flicker of hope right at the end. On Thursday, August 27th, we see a jump in the swell. The morning shows a 4 ft S swell with a 14-second period, which is a bit of a groundswell. The energy bumps right up, which is strong. That's the most interesting thing we've got in the whole outlook. The wind is light from the SSW, so it might be clean, but the afternoon gets messy with a cross-onshore. The problem is the forecast still says "marginal" at best, and the swell is coming from the south, not the west. For a jetty, that S swell might wrap in, but it's a long shot and a long way out.
Overall, this is a tough one. If you're a die-hard, August 27th morning is your only window to paddle out, but don't expect much. For most of us, it's not worth the effort.
Rusty.
