Table - best surf conditions forecast for Rincon - Rivermouth over the next 16 days.
The Lowdown
Alright, Rusty here again. Let’s break this down in feet and degrees.
Right now, things are pretty flat. The swell energy is a weak 69, and the water is sitting at 69°F, which is a solid 6°F warmer than average – that’s really unusual, feels like a warm bath out there. The first real chance to get wet won’t be until the afternoon of Saturday the 24th, and even then it’s just 1ft of swell with a 17-second period. That long period will give you glassy, clean conditions with that light cross-off wind, but the push is minimal. For the next few days, we’re looking at tiny surf, mostly 1ft to 2ft, from Sunday the 25th through Tuesday the 27th. Clean but barely rideable. The morning of Saturday the 29th offers a bit more with 3ft of SSW swell and light wind, but the real gem is much further out. The standout window is the afternoon of Friday the 4th of September. That’s when we get 3ft of long-period SSW groundswell (19 seconds) packing some serious energy (773) and a clean cross-off breeze. That’s the session to plan for. The next morning, Saturday the 5th of September, also looks solid with 3ft of SSW swell and similar clean conditions. That long period means the sets will be well-spaced and lined up perfectly for the Rivermouth point, though it can make beach breaks a bit straight. Crowds are often a factor here, so expect company. Into the second week, the afternoon of Thursday the 3rd of September brings a nice pulse of energy (455) with 2ft of long-period SSW swell and a gentle clean breeze – promising, but it’s a week out so don’t lock it in yet.
Rusty out.
