The Lowdown
Alright, let’s talk about what’s happening with the local surf. This is Rusty, and I got just one spot to talk about: Navarro Rivermouth. It’s a river mouth break, good for beginners, but it’s *inconsistent* and only *rarely breaks*, so you gotta be patient. Water temp is 56°F, which is pretty normal for this time of year, so a 4/3 wetsuit should be fine.
We’ve got a rough stretch ahead. From Sunday, July 26th to Friday, July 31st, it’s mostly a write-off. Winds are cross-onshore at 9 to 16 mph, making the surface choppy and messy. The swell is coming out of the NW, but it’s short period, only 5 to 8 seconds, so the energy is weak to moderate (61 to 640). The wave comment says *poor surf conditions* for all of them. No standouts here – it’s not a good time to be in the water.
Moving into the first weekend of August, Saturday the 1st and Sunday the 2nd, we get some size, with waves in the 7 to 10 ft range out of the NW, but the period is still short, just 7 to 9 seconds. The energy is strong (516 to 1264), but with the cross-onshore wind and those short periods, the quality is poor. The wave comment says *poor surf conditions*. For a river mouth, this is looking more like a kitesurfing day.
Then, from Monday the 3rd of August onwards, the wind starts to calm down. We’re looking at 6 mph winds from the WNW or W, sometimes becoming onshore or light cross-onshore. That’s much better. From Monday the 3rd through Thursday the 6th, the swell is 7 to 7 ft from the NW, with the period stretching to 8 to 10 seconds. The energy is moderate to strong (635 to 995). The wave comment changes to *marginal surf forecast or questionable tide conditions*. Not perfect, but way better than the week before. Still not the highlight, but it’s a step in the right direction.
Now, the one to watch is Monday the 10th of August. The swell is predicted at a solid 12 ft from the NW, with a 9-second period. The wind is a gentle 9 mph from the NW, but it’s cross-onshore. The energy is massive, 1809 – that’s a very strong system. The wave comment says *wind and tide favorable, but the swell is predicted to be too big for this break*. For a river mouth, that’s expert-level size. The period is a bit short for waves that size, but the energy is there. If you’re an experienced surfer, it could be a wild session, but it might be too much for the break to handle. It’s the best on offer, but it’s a long way out, so keep an eye on the forecasts.
Bottom line: the first week is pretty much a bust. The second week gets better, especially when the wind calms down. The 10th of August is the one that could be a standout, but only for the brave. Otherwise, keep your expectations low.
