Alright, crew. Rusty here. Let's cut through the fluff. This stretch for Navarro Rivermouth is a real bummer. This is an inconsistent river mouth that doesn't fire often, and the next 16 days prove it. The water's a bit colder than usual for this time of year at 53°F, so bundle up.
The first week is a total washout. From Tuesday the 7th all the way to Monday the 13th, we've got steady moderate cross-onshore winds from the NW ruining everything. Yeah, there's some swell – the combined wave energy is moderate to strong (ranging from 312 to 1191) – but it's mostly short-period junk at 6-8 seconds. The waves are choppy and poor. Don't bother.
There's a serious gap with nothing to recommend from around the 14th to the 16th. It's a blank spot on the calendar.
So, what's the best we've got? Around Saturday the 18th and Sunday the 19th, the wind drops back to a light breeze. It's still cross-onshore, so it won't be glassy, but it's a lot better. The swell runs 7ft to 8ft from the NW, and finally the period stretches to 9-10 seconds, giving the waves some shape and power. The energy is strong (828 to 1293). It's marginal, not great, but it's the only game in town. With the swell over 5ft, it's not a beginner's day.
The true standout? Focus on Sunday morning, July 19th. A light breeze from the WSW, a 7ft NW swell with a 10-second period. Wave energy is strong at 1215. It's the cleanest option, but it's still a cross-onshore setup. You'll get waves, but they'll be a bit bumpy. That's the pick of the litter.
After that, it fades back into poor conditions through the final week. It's a tough outlook. Sometimes you just have to take what the ocean gives you, and right now, it ain't giving much.
Rusty.
