The Lowdown
Alright, Rusty here again. Let’s break down the Bolinas Jetty forecast for the next 16 days, but in feet and miles.
It’s a slow start for a few days. Monday and Tuesday of this week are pretty much a bust, with waves under 2 feet and messy winds. Wednesday and Thursday aren’t much better, though Thursday afternoon sees a bump to about 4 feet, but it’s short-period and choppy.
The real change starts Friday, 4th September. We’ve got a 3-foot SW groundswell with a 18-second period, and the water temp is about average for this time of year. The combined energy is moderate (751), and by Friday afternoon the wind goes cross-offshore, cleaning things up. It’s still not perfect, but you can see it coming together.
Saturday, 5th September morning is the first true highlight. Glassy conditions, 3 feet of SW swell at 16 seconds, and moderate energy (607). This is your best early call for a clean, fun session on a longboard or a fish. Sunday morning, 6th September, offers a similar deal with glassy conditions and 3 feet of SSW swell. Crowds are possible, so get there early.
The following week is a mixed bag. Monday, 7th September morning is another glassy window with 2-foot SW swell, but it’s tiny. The real power comes in the second week. From around Thursday, 10th September, the swell builds again, with WNW groundswell hitting 4 feet on Friday morning, 11th September, and 5 feet on Saturday, 12th September. Cross-shore winds keep it rideable.
The big standout is Monday, 14th September morning. We’re looking at 6 feet of WNW swell with a 9-second period, and the wind is glassy. The combined energy is strong (720), and the conditions are very good. This is a powerful session with some real punch. A bit much for beginners, but intermediate to advanced crew will be stoked. Tuesday morning, 15th September, is also a cracker with 7 feet of WNW swell, glassy wind, and strong energy (861). That’s a serious day in the water, though the long-period groundswell might break a bit straight at the beach, so know your spot.
So, a slow start, a couple of nice glassy mornings early on, and a heavy-hitter window in the second week. The 5th and 14th are your best bets.
Rusty.
