The Lowdown
Alright, I gotta be straight with you: the next couple of weeks are looking pretty flat. Ano Nuevo is the only game in town, and it’s not offering much. We’re looking at nearly ten days of junk – tiny, weak swell and cross-shore winds making everything choppy and poor. The energy is barely registering, mostly under 550, and it’s just a whole lot of nothing.
The first real glimmer of hope hits on Saturday, August 29th. The energy jumps way up to 971, and we get a 4ft SSW swell with a long 18-second period. The wind is still cross-shore in the morning but it’s light, around 9 mph, so there might be some clean-ish waves to be had. Still, it’s a marginal call, only a 1 out of 10, so don’t get too excited.
Your best bet is Sunday, August 30th. The swell holds at around 4ft from the SSW with that same long 18-second period, and the energy is still strong at 846. The wind is the key here – it goes light and onshore at just 3 mph in the morning, which could make for some real glassy conditions. It’s not a big swell, but it's the cleanest we’ll see. This is the one to mark on the calendar.
After that, it’s back to mediocrity. The swell drops off and the period shortens, and those light, cross-onshore breezes are back, keeping the surf marginal. The second week looks pretty weak, with the swell bouncing around 3ft but lacking any real punch or consistency. The water is sitting at 61°, which is a touch warmer than usual.
Keep in mind, this spot is inconsistent. It's a beach and reef setup, so it needs everything to line up. With the winds and the swell direction we’re seeing, it looks like it might be a better week for the kite surfers than for us. But hey, forecasts change. As it stands, keep your eyes on Sunday the 30th. That’s your best shot.

Further information to help with frequently asked questions about our surf forecast for Ano Nuevo may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
