The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Nera Rivermouth.
Right off the bat, I gotta be straight with you – this is a tough one. The outlook for the next 16 days is pretty grim. We're looking at a long stretch of poor surf conditions and onshore or cross-shore winds that just won't let up. The water temp is sitting at 73°, which is about 0.5° above normal for this time of year, so pretty average.
The only real window that might get your heart pumping is around Saturday the 12th of September. We've got a big bump of swell coming in at 10ft from the SSW with a period of 17 seconds, and the combined energy is a massive 4809 (moderate to strong). That's a lot of water moving. But here's the kicker – the wind is hammering from the SE at 19 mph, ripping straight across the break. That's going to make it lumpy, chopped out, and pretty messy. It's only a marginal call at best, and honestly, for a river and beach setup like this, that much wind with that size swell is going to be a bit of a washing machine. That 10ft is way over the 8ft mark, so this is strictly for the experts only, and they'll have to deal with the chop. The period is long, over 15 seconds, which is good for energy, but at a river mouth, it might just break too straight.
After that, the swell drops right off again. We see a little pulse on Friday the 18th of September with 5ft swell from the SSW and a period of 18 seconds, putting the combined energy at 2005 (moderate). But once again, the wind is a cross-shore mess from the SE at 22 mph. It's the same story – marginal surf, lumpy, and not worth the paddle out for a clean wave.
The rest of the 16 days are filled with tiny swells, flat spells, or those same poor wind conditions. There is no standout session here. For a spot that's already inconsistent and sheltered, this is a blank run that's pretty normal for the area. If you're looking to get wet, you might be better off with a kite in that strong cross-shore wind, because for a paddle surfer, it's a long wait for something decent.
Rusty.
