Table - best surf conditions forecast for Navarro Rivermouth over the next 16 days.
Alright, Rusty here. Let’s break down what’s in store for our local spot, Navarro Rivermouth. First week and a half is a tough one. Starting Friday the 10th, through to Saturday morning the 18th, we’re dealing with northwest winds cross-onshore at 10 to 20 mph, turning the surface into a mess. Swell runs between 6 and 10 ft from the NW, period short at 7-8 seconds, combined energy between 331 and 1423 (moderate to strong), but with that wind it’s just poor – not worth paddling. On Wednesday the 15th afternoon, we get 10 ft with 1423 energy and 20 mph cross-onshore – that’s expert-only and still ugly. No good calls in that stretch.
Water temp starts at 54°F, with an anomaly of 1°F below average, so nothing out of the ordinary for this time of year.
Here’s your standout: Saturday the 18th afternoon. Glassy conditions, wind at 5 mph from the WNW, and the wave comment says “expect very good surf conditions.” Swell is 3 ft with a WNW direction and a 16-second period – groundswell, real long lines. Combined energy still solid at 1046. It’s small but clean, and the river mouth setup will hold it well. Crowds are listed as “often,” so expect company. That is your best session of the whole window.
After that, Sunday the 19th and Monday the 20th morning are mixed, but from Monday afternoon the 20th we’re back to NW cross-onshore chop, 8-second period and poor conditions straight through to Saturday the 25th. A couple marginal moments on the 23rd and 25th, but nothing worth chasing.
So rough it out through a long stretch of dirty surf, then go all-in on Saturday afternoon the 18th for that glassy, long-period groundswell. Small but clean.
