The Lowdown
Alright folks, Rusty here. Let’s check out what’s cooking at the Navarro Rivermouth for the next couple of weeks.
Right off the bat, it’s a rough stretch. This spot is inconsistent, and we’re staring down a long run of onshore wind and messy surf. The first chance to even consider a paddle is Sunday, July 19th, but it’s a marginal call. You’ll see a small 3ft swell from the WNW with a very long 15-second period, but the wind is onshore at 6 mph. The combined swell energy is moderate (925), but the quality is just not there. The water temp is about average for the season.
After that, things go south. From Monday, July 20th through the end of the month, it’s all cross-onshore wind, mostly from the NW, and short-period slop. The swell tries to build, but it’s wind-chopped and ugly. By Tuesday, July 29th, the swell is predicted to be too big for this break at 12ft, and even with the wind still cross-on, it’s a washing machine for experts only. The combined energy hits 1546 (very strong) that afternoon, but with the wind, it’s a mess.
The one tiny window might be the last few days of the month. On Thursday, July 31st, the morning shows an 8ft groundswell from the NW with a 9-second period and a gentle breeze at 9 mph. The combined energy is strong (1898), but it’s still cross-on. For a rivermouth, that long-period groundswell and cross-on wind is a real gamble. It’s marginal, but it’s the closest thing to a pulse we’ve got.
Honestly, for the next 16 days, this is a kite surfer’s window, not a paddle surfer’s. The wind is up, the swell is big, but the quality is poor. If you’re a beginner, stay away – the swell is too big and the conditions are too rough from the 25th onward. The pattern is persistent, but it tends not to stay this poor forever.
Rusty.
