Navarro Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what the Navarro Rivermouth has got cooking for us over this 16-day stretch.

Right off the bat, I gotta be straight with you: it’s a bit of a rough start. The first real entry on the 9th of August is already messy with cross-onshore winds and a bumpy 8ft to 8ft NW swell. The energy is there—moderate to strong with combined energy readings between 823 and 1020—but the wind is just ruining it. That’s a hard pass for paddle surfing; if you’re into kiting, that setup might look a bit more interesting.

We move into Monday the 10th and Tuesday the 11th, and honestly, it’s still not great. The swell sticks around the 7ft to 8ft mark from the NW, but it’s described as marginal or questionable at best. The wind is mostly light and cross-on, so the surface is a bit bumpy with small wind ripples. It’s not a total washout, but it’s not calling me down to the water. This kind of "meh" run lasts right through until the end of the week around the 14th, when the swell really drops off. From the 14th to the 17th, we’re talking ankle-snappers—2ft to 3ft—with a combined energy barely cracking 87. It’s a proper lull.

There’s a gap of quiet, weak surf for about four days there, from the 14th to the 17th. Then we see a slight flicker on the 18th with a 3ft SW groundswell coming in at a 12-second period, but the combined energy is still weak at 228, and the wind is crossing it up. Still, the period is a bit longer here, which suggests maybe a cleaner shape if the banks hold, but the size is too small to get excited.

The standout for this whole window? You’ve got to look ahead to Friday the 21st and Saturday the 22nd of August. The swell kicks back up to 6ft–8ft from the NW, and while the wind is still cross-on, the energy is back in the moderate to strong range (460 to 1194). It’s not perfect, but it’s the best we’ve seen in a while. That said, keep in mind this spot is a rivermouth, it’s fairly exposed, and the optimum direction is NW, so the direction is right. But it is inconsistent, and the crowds are often an issue here. Being a rivermouth, that longer-period NW swell can sometimes race past the sandbars, so it’s not a guarantee for perfect walls.

After that, on Sunday the 23rd and Monday the 24th, we get a weird one. The swell drops to 2ft but the period jumps to 18–19 seconds from the SW. That’s a very long period groundswell, but the size is tiny. The combined energy is still weak (373–435). For a rivermouth, a long period like that can be tricky; it might just make it too straight. But if the tide lines up, you might snag a weird, clean little wave.

All in all, there’s no real "go-day" in this outlook. The first week is average at best, the middle is flat, and the second week offers a bigger swell but with onshore or cross-onshore winds that keep it from being stellar. The best bet is probably Saturday the 22nd of August for size, but don't expect perfection.

Stay patient, keep an eye on the wind shifts.

Rusty.
