The Lowdown
Alright folks, Rusty here. Let’s get straight into it. Honestly, the outlook for Navarro Rivermouth over the next 16 days is a tough one. We’re looking at a long stretch of poor surf and tricky conditions, with very few windows worth paddling out for.
The first real chance to even think about a wave doesn’t come until Saturday morning, July 18th. Even then, it’s marginal. The swell is coming from the WNW at 3 ft, with a long period of 16 seconds, which is a proper groundswell. The energy is moderate, at 1099, but that long period can make a river mouth break a bit tricky, often running too straight. The wind is onshore, so it’s not going to be clean. The water temperature is 54°, which is a bit colder than normal for this time of year.
The only real standout, and I mean the only one worth a mention, is a very brief window on the afternoon of Friday, July 24th. The wind is glassy, which is a massive positive for a spot that usually runs cross-onshore. The swell is small at 2 ft from the NW with a period of 8 seconds, and the energy is weak at 69. It’s a tiny wave, but for a river mouth that’s inconsistent, that glassy surface will make it look a lot better than anything else in the window. Don’t expect much, but it’s the best of a bad bunch. Crowds are often a factor here, so on that one glassy afternoon, it might be busier than you’d hope for such small surf.
The rest of the period is dominated by windy, choppy cross-onshore conditions, with swell heights typically between 4 ft and 8 ft, but the wind is just ruining it. The period is short, mostly 6-8 seconds, with moderate energy readings. For a few days around July 16th-17th, the swell is bigger (over 8 ft) and combined energy hits four digits, but the wind is strong and cross-on, making it a total mess. That’s more of a kite-surfing setup than a paddling one.
The gap between the poor and marginal days is huge. Don’t hold your breath. It’s a rough run for this spot.
Rusty.
