The Lowdown
Alright, this is Rusty comin' at ya. Let's be real, this forecast for our spot is a tough one. For the next week at least, we are staring at a whole lot of nothing good.
Looking at the entire run, the surf just doesn't want to show up. Nera Rivermouth is the only break on the radar, and it's a sheltered, inconsistent river-and-beach setup that really needs a proper push from the southwest to get going. The good news is that the swell direction is consistently coming from the SSW, which is right in its wheelhouse. The bad news is the size is just tiny, and the winds, apart from a very brief window, are junk.
Water temp is sittin' around 74°F, which is bang on normal for the time of year, so no surprises there.
The first real chance to even think about paddling out is Friday, July 31st. We get a little bump from the SSW, around 3 ft with a 14-second period. The headline here is a glassy morning – absolutely dead calm, with the combined energy a weak 236. It’s surfable, but only just. We are talking small, clean lines for a longboard or a foiler.
That glassy window slams shut by the afternoon, and from there it’s a grim run. Saturday, August 1st gets hit by rain and a strong 19 mph cross-onshore wind. The energy spikes to 725, but it’s a lumpy, choppy mess. Not worth it.
For the next week after that, it’s a write-off. Strong winds, mostly cross or cross-onshore from the southeast, keep everything blown out. We get a few tiny, clean pulses on the 4th and 5th of August with 3 ft SSW swell and 16-18 second periods (energy around 284-387), but the wind is always from the side, ruining any chance of a clean wave face.
The one long-range standout that’s worth keeping an eye on is Wednesday, August 12th. We’ve got 3 ft of SSW swell with a solid 15-second period for the morning, and the combined energy climbs to 444. The wind is only a light 6 mph cross-onshore – not perfect, but manageable. This might actually be the best wave of the whole two weeks. Keep a very loose eye on it, but don't hold your breath.
Overall, the first week is a dud. The second week offers a few more clean-ish options, but nothing that will get your heart racing. For a spot that's already inconsistent, this is a pretty normal blank run. Don't be surprised if the forecasts shift for the better, though.
Alright, that’s the long and the short of it.
Rusty.
