The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s shaping up for the Navarro Rivermouth stretch over the next couple of weeks. I’ll be straight with you – it’s a rough run for most of the forecast, and there’s not a whole lot to get excited about for a while.
The first real surfable day isn’t until the 2nd of August, and even then, it’s tough. We’ve got a solid 7 ft to 10 ft of swell coming in from the NW, but the wind is a persistent problem. That combined swell energy is ramping up from a moderate 1202 to a very strong 1600, but it’s all being wrecked by cross-onshore winds that keep the surface choppy and messy. The swell period climbs to a decent 9 to 10 seconds, which is okay for a river mouth, but the wind just won’t cooperate. The water temp is about 57° around the start, which is normal for this time of year.
The real kicker is that the 10 ft swell from the 2nd to the 4th of August is too big for beginners and really only for the experienced crew. Even then, the quality is poor. The wind is always cross-onshore, and the break is inconsistent, so you’ll be waiting around for a set that’s likely lumpy. I wouldn’t call anything here a standout.
Then, on the 5th of August, Wednesday afternoon, we get a brief moment of hope. The wind drops to a glassy 3 mph from the west, and it’s the only time in the whole period you’ll see that word “glassy.” The swell drops to a manageable 5 ft from the NW with an 8-second period, and the combined energy is a moderate 391. This is the best on offer, and really the only chance for a clean wave. It’s still a river mouth and it’s inconsistent, but if you time it right, you might get a few fun ones. Crowds are possible here, so keep an eye out.
After that, from the 6th of August onward, it’s back into the gutter with poor surf conditions and marginal forecasts. The wind goes light and variable, but the swell is dropping and the period stays short, so the energy is weak. There’s nothing else to recommend.
So, to sum it up: the first week is a no-go with no recommendations. The second week has a few days of big, messy swell for experts only, but the only real shot at a decent surf is that glassy window on Wednesday the 5th of August. If you’re desperate, that’s your moment.
Rusty.
