The Lowdown
Alright, Rusty here, pull up a sand dune and let me give you the straight story on what's cooking for Navarro Rivermouth over the next couple of weeks.
Honestly, it's a bit of a rough patch to start. This spot is a river mouth, and it's inconsistent at the best of times, so you really need the stars to align. The water's sitting at 56°, which is about average for this time of year, so no surprises there.
The whole first week, from Monday the 27th of July right through to Sunday the 2nd of August, is a write-off. The wind is a persistent cross-on shore, blowing 9 to 19 mph, and the swell is just a messy, short-period windswell. The wave energy is all over the place, but the quality is junk. The surf is just too choppy and lumpy to be worth paddling out for a typical surfboard. Honestly, with the combination of strong, consistent cross-shore wind and a decent amount of swell, this setup looks more interesting for kite surfing than paddle surfing.
We finally get a bit of a window starting Monday the 3rd of August. The wind drops to a gentler breeze, but it's still cross-on. The swell is a solid 10 ft from the NW, with a period of 9 seconds, which is pushing into proper groundswell territory. The energy is strong, hitting 1345 on Monday morning. It's still a bit messy, the forecasters are calling it "marginal," but it's the best we've seen in a long time. The swell is big, over 8 ft, so this is for experienced surfers only. The NW swell direction is what this rivermouth wants, but it's not a clean day.
The best chance for a decent wave looks to be from Tuesday the 4th of August through to Thursday the 6th of August. The swell eases a bit, dropping from 8 ft down to 7 ft, but the period lengthens to 10 seconds. That's a proper groundswell, and it'll hold its shape better. The wind is still cross-on, but it's a light breeze, so the surface won't be too chopped up. The wave energy is in the moderate to strong range, between 784 and 1285. It's not perfect, but for a spot that's been blowing out all week, it’s the most promising run. The swell is still over 5 ft, so it's a bit much for beginners, but it's a good step down for the more experienced crew.
After that, from Friday the 7th of August, the wind picks up again and the quality drops off. The 9th and 10th of August look like another poor stretch, though there's a hint of a marginal session on the afternoon of the 10th with an 8 ft swell and a light wind. But it's a long way out and the pattern has been rough.
To sum it up, there's nothing worth chasing for the first week. The best bet is to keep an eye on that window from Tuesday the 4th to Thursday the 6th of August. It's not a classic, but it's the only chance of a salvageable session in the next sixteen days.
