The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s shaping up for our local lineup.
To be straight with you, the next sixteen days are a real mixed bag. We’ve got some small clean windows, but nothing that screams 'drop everything and go'. The water’s sitting at a pretty warm 60°, which is a touch warmer than normal for this time of year, so at least you won’t need a thick wetsuit.
The first real standout to mention is Thursday morning, the 20th of August. We’ve got a little bump of swell coming in at 4ft from the WNW. The period is short, only 7 seconds, but the wind is light and cross-offshore, keeping things clean. The combined swell energy is moderate at 440. It’s not going to be world-class, but for a quick log session or a longboard, it’ll be worth the walk down to Bolinas Jetty.
After that, the forecast gets a bit flat and ordinary for several days. Friday the 21st and Saturday the 22nd look poor, with tiny weak swell and shifty winds. We get another small window on Sunday morning the 23rd, with 4ft from the WNW, but the wind is cross-shore, creating a little ripple on the surface. Still rideable if you’re keen.
Now, if you can wait, the best bet of the whole period lands on Sunday morning, the 30th of August. The swell is a clean 3ft from the SW with a solid 16-second period—classic groundswell. The real kicker is the wind: it’s glassy. Absolutely dead flat. That means silky smooth conditions. The energy is moderate at 417. This is the morning to have a coffee and get in the water. The longer period will give you some good shape on the jetty.
There’s also a promising outlook for the 2nd of September, a Wednesday morning. Another glassy start, with 2ft of long-period swell from the SW at 17 seconds. It’s tiny, but if you have a log and love those long, gliding walls, this could be a real treat. The energy is moderate at 324.
Otherwise, it’s mostly small surf with cross-offshore winds during the second week. Not much to write home about. No huge swells, nothing for the experts, just small, clean conditions for the patient ones.
Stay frothy, catch you in the water.
Rusty.
