The Lowdown
Right then, let’s have a look at what’s on offer. The whole 16-day window is a bit of a mixed bag, but there’s a couple of moments that could be worth a look if you’re patient. The water temp is sitting at 55°, which is a bit colder than what we’d usually expect for this time of year, so you’ll want the thick rubber.
The first few days, from the 31st of July right through the weekend, are pretty much a write-off. That northwesterly wind is just too strong and cross-onshore, and the swell is all short-period wind chop at 7 to 8 seconds. It’s messy, it’s lumpy, and the combined energy is moderate early on (284–355) but then it jumps up to strong (1118–2168) as the swell gets bigger, but it’s just not surfable. The waves are going to be 7 ft to 12 ft, but with that wind, it’s just a washing machine. This is a river-mouth break, so it's inconsistent at the best of times, and these conditions are just poor.
From Monday the 3rd of August, things start to settle down. The wind eases right off, going light and even swinging offshore at times. The swell settles at a solid 10 ft with a 10-second period from the northwest. The combined energy is strong (1523–1568), but the wind is light and variable. The morning of Monday the 3rd has a light cross-on breeze, but the afternoon looks better with the wind going light and offshore. This is the pick of the first week, but it’s still only a marginal call. The break is inconsistent, so you’ll need to be patient and pick your moment.
The following week is a grind. The swell drops back to 7 ft–8 ft but the wind is mostly cross-onshore again, keeping it choppy. On the 4th and 5th of August, there are afternoons with light offshore winds, but the swell is a bit soft and the short 9-second period doesn’t help. The combined energy is moderate (740–883). It’s not terrible, but it’s not a standout.
The best chance of the whole forecast comes on Saturday the 8th of August. The afternoon has a 13 ft swell from the northwest at 10 seconds, with a light cross-onshore breeze. The combined energy is very strong (2614). The catch is that at 13 ft, this is only for experts. It’s going to be a big, powerful river-mouth wave. If you’re experienced and you time it right, this could be the day. The crowds are listed as ‘often’, so expect company.
After that, it fades. The second week sees the swell drop back to 4 ft–8 ft, and the wind is mostly cross-onshore or moderate, keeping the surf choppy and poor. The long period groundswell showing up on the 13th of August (3 ft, 16 seconds) is a tease, but it’s small and the wind is onshore again. The combined energy (890) is moderate, but it’s not going to be a clean wave at this break.
In short, if you’re an expert, the afternoon of Saturday the 8th of August is your best bet for a big, powerful session. Otherwise, the light offshore winds on the afternoon of Monday the 3rd of August offer a smaller, cleaner window for the more patient surfer.

Further information to help with frequently asked questions about our surf forecast for Navarro Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
