Bolinas Jetty Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s coming up for Bolinas Jetty.

Right off the bat, I’ll be straight with you – there’s a quiet spell to start. The early part of the outlook is pretty lackluster, with small, weak swell and poor conditions that aren’t worth paddling out for. The water temp at Bolinas Jetty is sitting at 62°, which is a touch warmer than normal for this time of year, so at least it won’t be a shock to the system.

The first real chance of anything decent doesn’t show until the morning of Monday the 14th of September. That morning, the swell is coming in from the WNW at around 5ft, with a period of 9 seconds, and the wind is glassy from the SSW at just 3 mph. That’s a clean window, and the wave energy is moderate (434). It’s not huge, but the glass means smooth faces. That said, the afternoon picks up a 16 mph cross-offshore breeze, so make the most of the morning.

We see a bit more size on the morning of Tuesday the 15th – 6ft from the WNW, but the period drops to 8 seconds and the wind is stiffer at 16 mph cross-offshore. The combined energy is moderate (522), but the quality isn’t there for a standout session. It’s more of a choppy, lumpy day.

Looking further out, the late period has some real promise. On the morning of Saturday the 19th of September, we’ve got a clean, glassy morning with no wind at all from the south, and a 2ft SW swell at 18 seconds – that’s a long-period groundswell. The energy is moderate (319). That long period will wrap nicely around the jetty, but at a beach/jetty setup, it might break a bit straight. Still, glassy conditions and that kind of period mean you’ll get some lined-up, shapely runners if you pick your takeoff spot right.

Then, the morning of Monday the 21st of September is another standout: 3ft SW swell at 17 seconds, glassy wind from the south at 3 mph, and combined energy is moderate (429). Again, glassy and clean with long-period groundswell – these are the sessions to circle. The wind stays light or glassy on the mornings of the 22nd and 23rd as well, with consistent 2ft to 3ft SW swell at 16–17 seconds, though the energy dips a little.

All in all, the standout is the morning of Saturday the 19th of September and the morning of Monday the 21st of September – both glassy, both carrying that long-period SW groundswell, bringing clean, rideable waves. Crowds are worth noting: it’s marked as ‘sometimes’ at Bolinas Jetty, so you might have company on those glassy mornings. But with that quality, a few others will be thinking the same.

Rusty.
