The Lowdown
Right, let's talk about the local stretch. It's a tough read. We’ve got a long, flat, and choppy patch ahead of us. The swell is weak to moderate, and there's a cross-onshore breeze messing with nearly every session.
For the next week, it’s almost all poor. The water temp is about what you'd expect for the season.
The only tiny glimmer of hope, and it’s a small one, pops up around Thursday, September 3rd and into Friday, September 4th. On the morning of the 3rd, there's a pulse of moderate energy (680) with a very long period swell from the SW hitting about 3 ft. The wind is a light cross-onshore from the WNW at about 6 mph. It’s still marginal, but that long period could give you a few clean ones. The next morning, the 4th, is similar with the same energy (680) and a pulse of 6 ft from the NW, but again with a light cross-onshore from the WSW.
This spot, Navarro Rivermouth, is an inconsistent one, so a dry run like this, while a bummer, isn't a huge shock. The second week looks even weaker and more wonky. There’s no real standout day, no reason to paddle out. With the constant chop and weak surf, this setup looks more interesting for a kite than a surfboard.
Your best bet is to keep an eye on that first Thursday/Friday in September, but don't get your hopes up. It’s shaping up to be a lean grind.
