The Lowdown
Alright folks, Rusty here, and the only game in town for this forecast is Navarro Rivermouth.
I gotta be honest with you, it's a tough run. We've got plenty of swell coming, but the wind just won't get out of the way for most of it. The water's sitting at about 57°F, which is dead normal for this time of year, so no surprises on what to wear.
The first real action is on Wednesday the 29th, but it's a no-go. We've got 7ft of NW swell with a short, weak period of 7 seconds and a stiff 25 km/h cross-onshore wind. The energy is moderate (379), but the surface is just chop. Save your wax.
This same story of NW swell and cross-onshore wind just keeps playing out. Thursday the 30th and Friday the 31st are the same deal—head-high waves, but all blown out. The wind backs off a little Thursday afternoon to 15 km/h, but it's still cross-onshore, so it stays fairly choppy.
Then it gets proper big. Saturday the 1st of August the swell jumps to 12ft in the afternoon with an 8-second period and a fresh 30 km/h cross-onshore wind. That's a lot of energy (1560), but it's just big, lumpy, and windy. This is strictly for experts, and even then, it won't be pretty. With that beach setup and those winds, the kiters are gonna have a field day.
That big swell hangs around through Sunday the 2nd into Monday the 3rd, with waves between 10ft and 13ft. The period stretches to 9 or 10 seconds, which means more energy underneath, but the wind is still cross-onshore, ruining the surface. Monday afternoon is the first thing that gets a score of 2 out of 10—a hint of something rideable, but it's still described as marginal.
The best window in this whole outlook shows up around Tuesday the 4th of August and runs through the end of that week. The swell drops to a more manageable 7ft to 8ft and the period stays around 9 to 10 seconds—that's proper groundswell. The wind finally cooperates, turning light and variable, with a few windows of light cross-onshore and even some "on" conditions on Wednesday the 5th afternoon and Friday the 7th morning. This is the pick of the period. The wave energy is moderate to strong (828 to 1226), and the lighter breeze means cleaner waves. Remember, this is a rivermouth, so that longer-period swell will wrap in and stand up, but it's an inconsistent spot. With the right tide, this is your best bet all week.
Looking further out, it's more promising but less certain. Around Saturday the 8th and Sunday the 9th, the swell jumps back to 10ft with a 9-second period, and we have more light wind windows. The energy hits a massive 2590 at one point. With that much power at a point/reef setup, this could be a freight train. But we're talking a week and a half out, so it's a promising idea, not a guarantee.
The final days, from Monday the 10th through Thursday the 13th, the swell fades to 5ft to 7ft, but the wind turns cross-onshore and fresh again, killing the quality.
So, here's the takeaway: the first weekend is a wash. Your best bet is the mid-week window around August 4th through 7th when the winds go light. And keep a close eye on that weekend of August 8th-9th for a possible standout, even if it's a long-range tease.
Stay stoked,
Rusty
