The Lowdown
Alright, this is Rusty, and I'm lookin' at what's on the cards for Nera Rivermouth over the next couple of weeks. Gotta be straight with you – it's a tough outlook. This spot is a sheltered river and beach break that's inconsistent even on a good day, and the forecast is mostly serving up a lot of nothing with a side of cross-shore chop.
The water temp is sittin' at a pretty normal 74°, so nothing wild there for the time of year.
Right now, on Thursday the 30th, we're lookin' at tiny 1 ft swell from the SSW with a long 16-second period. The wind is a light cross-offshore, keepin' it clean, but there's just no energy to work with – the combined swell energy is only 102, which is weak. It's a no-go.
Friday the 31st is our one little glimmer. Friday mornin', we get glassy conditions with no wind at all, and the swell bumps up to 3 ft from the SSW with a 14-second period. The energy climbs to a modest 236. It's surfable, but it's very ordinary. For an inconsistent spot like this, a glassy morning with knee-high waves might be your only chance all week, but don't expect much. The afternoon gets messy again.
From Saturday the 1st of August all the way through to Wednesday the 14th of August, it's a long, bleak stretch. The swell drops out completely for days, or it's blown out by moderate to fresh cross-shore winds. We see energy numbers in the weak range (12 to 179), and the wave comments are all about "poor surf conditions". There's no standout period here. The swell that shows up on the 4th and 5th of August peaks around 3 ft from the SSW, but with a solid 19 mph cross-shore wind from the SE, it's just choppy and lumpy. Not for a paddle board.
Even the longer period swells over 15 seconds that pop up here and there won't save it, 'cause they're tiny and the wind is always working against 'em.
Honestly, for this whole 16-day window, the only session with a shred of promise is the glassy Friday morning. But given it's an inconsistent break with only "sometimes" crowds, you might have it to yourself, if you can wrangle a wave out of it.
This is a classic case of an area that often goes blank. It tends not to stay poor forever, but this run is lookin' pretty much done.
Rusty.
