The Lowdown
Alright, Rusty here. Let’s break down Nera Rivermouth over the next couple weeks. This spot is a sheltered river and beach break in the Nera-Rivermouth area, and it’s gonna be a patience test.
Right now, Wednesday the 5th is pretty much all we’ve got in the short term. Expect a clean 0.8m SSW swell with a long 16-second period – real groundswell. Combined energy is 291, which is a moderate push. Wind is a light cross-off from the ESE at 9 mph, so the surf will look tidy. Water temp is 73°F, about normal for this time of year. Still, this isn’t a standout day – more of a “happy to be out” session. Then Thursday the 6th drops right off a cliff.
From Thursday the 6th all the way through to the middle of the month, it’s a big fat gap. Tiny waves, poor energy, and a lot of cross-shore or onshore chop. There’s a glimmer of glassy offshore wind on Thursday afternoon the 6th, but with no swell at all, it’s just a flat, shiny ocean. Nera Rivermouth isn’t a consistent spot, and this run proves it.
Now, hang tight, because things try to kick off around Saturday the 15th. That morning we’ve got a glassy offshore breeze from the WSW at just 3 mph and a 0.6m SSW groundswell with a 19-second period – super long period. Combined energy is 246, moderate. The waves will be clean and lined up, but it’s small, so really only one for the logs or a beginner on a good day.
The real standout is Sunday the 16th in the afternoon. We’re looking at a clean 1.6m SSW swell, period 18 seconds, with a cross-off breeze from the ESE at 6 mph. Combined energy jumps to 1591 – strong, proper wave energy. This is the one to get excited about. The morning of the same day is also worth a look: a 1.0m, 19-second SSW swell with very light cross-onshore wind – energy at 1224 – might be a bit lumpy but has grunt. These are all about a week and a half out, so keep an eye on it.
Monday the 17th keeps the potential alive with a clean, glassy offshore morning: 1.4m, 16-second SSW groundswell, combined energy 1055. That’s strong, with light wind. Grab that window, because the afternoon brings rain showers and a cross-onshore breeze. After that, the energy fades and the wind turns onshore again through the end of the outlook.
Bottom line: if you can wait, the weekend of the 16th and Monday the 17th are your best shots. The rest is mostly flat or choppy – might be better for kitesurfing than paddling.
Rusty.
