The Lowdown
Alright, Rusty here again. Let's get the lowdown on this spot.
We're looking at Nera Rivermouth, a sheltered river and beach setup that's best for beginners, but it's inconsistent. For the first few days, there's a little bit of energy in the water, but the wind just won't play ball. Friday morning the 31st is the best of a very average bunch, with a clean 2.6ft SSW groundswell, a 14-second period, and glassy conditions. The combined energy is moderate (236). That's your window to get something clean, but it's not surf that'll get the heart racing.
From Friday afternoon, things go downhill fast. The wind swings onshore and gets stronger, and the swell gets messy. Saturday the 1st is a write-off with fresh cross-shore winds, and Sunday the 2nd is flat. We go through a few days of tiny, clean waves from the 3rd to the 5th, but they're mostly under 2.6ft with light cross-offshore breezes, so the conditions are clean but the swell is weak. The combined energy on Tuesday the 4th morning hits a moderate 402, but it's a marginal, clean 2.6ft SSW swell.
The quality picks up a touch on Friday the 7th of August. The morning is glassy with a 2.6ft SSW swell (190 combined energy), and the afternoon actually sees a 3.3ft SSW swell with glassy conditions (282 combined energy). That's the standout for the whole outlook – a small window of clean, glassy surf. After that, it's mostly poor and choppy again, with a few completely flat days around the 10th. The 14th of August afternoon sees a bump in swell height to 4.6ft, but it's a short-period 8-second windswell, so it's going to be a choppy mess with the cross-onshore wind.
Overall, this is a patchy outlook. The best bet is that Friday the 7th, and even then, it's small. For a beginner-friendly spot, this is a week of watching and waiting.
