Nera Rivermouth Surf Forecast and Surf Report

Right off the bat, the surf's pretty much a no-show. We've got a stretch of tiny, wind-blown junk through Sunday the 31st and into Monday the 1st. It's a flat spell, and you won't find anything worth paddling out for. Honestly, it's looking like a bit of a drought to start this outlook, a good couple of days of nothing. But don't get too down, there's a pulse of energy coming our way.

The first real sign of life shows up on the morning of Tuesday the 2nd. Nera Rivermouth (Nera-Rivermouth) picks up a 5.9ft SSW swell with a long 15-second period. That’s proper groundswell energy, and we're looking at a combined energy reading of 1312, which is strong. The wind is light and cross-offshore in the morning, so it should be clean and glassy. This is a standout morning. With 5.9ft, it's getting a bit punchy for beginners, but for the average surfer, this is the best of the early run. After that, Wednesday afternoon and Thursday drop back off, with the swell fading and winds going a bit cross-onshore, leaving things lumpy.

Friday the 4th and Saturday the 5th are back to small, weak surf, with the energy dropping down to under 200. It’s not doing much. Then, we get another spike on the morning of Sunday the 6th. A 4.9ft SSW swell at 15 seconds rolls in, but there's an onshore wind attached to it. The combined energy is reading 1028, so the power is there, but the wind is going to mess it up. That's a heartbreaker. The period is nice and long, and there's proper push, but that onshore breeze is going to turn it into a messy, lumpy closeout. It's a frustrating one.

The following week is more of a slow build. Nothing on Monday the 7th or Tuesday the 8th is truly firing—just inconsistent, waist-high stuff. But keep your eye on the morning of Wednesday, September 9th. We're looking at a 3ft SSW groundswell, a 16-second period, and light offshore winds. The energy is moderate at 453, but the conditions will be clean and fun. It's not big, but it’ll be a fun little wave.

After another small blip, the energy really starts to wind up again. Friday the 11th morning has a 4.3ft SSW swell at 17 seconds and a moderate cross-offshore wind, with strong energy (980). That’s a good one, clean and with some push.

But the true standout of this whole outlook is the morning of Sunday, September 13th. We have a solid 6.2ft SSW groundswell, a long 17-second period, and light, clean cross-offshore winds. The combined energy is a massive 2137. This is the one to plan for. It's going to be powerful, organised, and clean. At 6.2ft, it's pushing into that "experienced surfer" territory, so know your limits. This is the day to circle on the calendar, the best of the lot, though it's still over a week away, so treat it as promising, not a done deal. The afternoon is slightly bigger at 6.9ft, but conditions look more marginal.

Beyond that, the energy drops back off. The water temps are sitting around 73.4°, which is about average for this time of year, so it's not a drama. The Rivermouth is an inconsistent spot, so when these pulses do line up with decent winds, you've got to jump on them. This is a patchy outlook with one gem hidden in the second week.
