Table - best surf conditions forecast for Navarro Rivermouth over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you: this is a tough one. The only spot on the books is Navarro Rivermouth, and to be honest, it’s a rough stretch ahead. We’ve got a solid 16-day window, but it’s gonna feel like a ghost town for the first week and a half for any decent surf.
This is a rivermouth, notoriously inconsistent, and right now the wind is a curse. All the way from Wednesday the 8th right through to the middle of the next week, we’re stuck with a persistent cross-onshore breeze. The swell is there, but it’s a mess. Even with head-high waves in the 5 ft to 8 ft range, the wind is just chopping it up, making it poor surf conditions day after day. The water is a bit colder than normal for this time of year, sitting at 53°F.
The energy builds up strong, hitting moderate to strong levels (428 to 1003), but it’s mostly short-period, wind-driven slop. By Thursday the 16th, the swell gets proper big, over 11 ft, but with that cross-wind, it’s just a washing machine. This is a beach-and-reef setup, and honestly, with that much wind and chop, it’s looking more interesting for kite surfing than paddle surfing.
The only glimmer of hope shows up much later. On Saturday the 18th, we finally get a shift. The wind swings around to a light breeze from the W, then WNW, turning offshore. The swell drops back to chest-high, around 6 ft, from the NW, but the period stretches to 9 seconds. It’s still cross-on, but the wind is light enough that the surface might clean up. This is the standout window. The morning of Saturday the 18th is the best on offer, with a marginal forecast but a chance of some clean, lined-up waves as the wind eases right off (combined energy 1376). It’s not a classic, but it’s the only real chance we get.
Keep in mind, this spot is inconsistent and can be crowded when it runs, so don’t sleep on that Saturday morning if you can get there. The rest of the second week is a dud, with weak, short-period leftovers and more cross-shore wind. A blank run like this isn’t unusual for a rivermouth, but it’s a bummer.
Rusty.
