The Lowdown
Alright, Rusty here. Let's break down the next couple of weeks.
The honest truth is, we're looking at a pretty rough stretch. The wind is gonna be a constant problem, blowing onshore almost the entire time, which means the surf is going to be choppy and messy. There are a couple of exceptions, but you'll have to wait for them, and they come with their own set of problems.
The only spot we're looking at is Navarro Rivermouth. It's an inconsistent river mouth that needs everything to line up, and it's just not getting the right conditions. The water temperature is about 60°F, which is a bit warmer than usual for this time of year, about 4°F above average, so that's a plus.
The first real chance of a wave doesn't come until Saturday, August 1st. The morning is still a washout with 8ft of swell from the NW and the usual cross-on winds. The afternoon is a different story. The swell jumps to 12ft from the NW, and while the wind is still a moderate cross-on, the forecast says the wind and tide are favorable. But here's the catch: 12ft is way too big for a river mouth. This is for experts only. The combined energy is a massive 1892, which is strong to very strong power. It's also a spot that's "often" crowded, so there will be a crew out there.
Then Sunday, August 2nd afternoon, it's the same thing. Another 12ft NW swell, favorable wind and tide, but again, it's just too big to be fun. Another 2053 in combined energy confirms it's a serious, heavy ocean.
After that, the forecast slides back into poor conditions. The next possibility is on Wednesday, August 5th. The morning sees a 8ft NW swell with a light onshore wind (10 km/h). The conditions are called "marginal," which is the best we've seen in a while, but it's still not clean. The afternoon is similar, with a 8ft swell and a light cross-on breeze. The period is a solid 10 seconds, which will give the waves some shape, but the wind will keep it bumpy. The energy is moderate (1121 and 1263).
Thursday, August 6th is more of the same – marginal conditions with a 8ft to 8ft NW swell. It's a tease, but nothing to get excited about. The last few days of the forecast just fade back into a consistent pattern of poor, choppy surf.
So here's the bottom line: the best you can hope for is the afternoon of Saturday, August 1st, or Sunday, August 2nd, and only if you are an expert who loves big, heavy, onshore-driven waves. For everyone else, the entire 16-day window is a write-off. The constant onshore wind and the river mouth's inconsistency make this look more interesting for kite surfing than paddle surfing. Keep your board in the car and hope the forecast changes.
