The Lowdown
Alright, let’s put it in feet and degrees. The Nera Rivermouth is the only break in the game for the next 16 days, so let’s see what’s on offer.
Sunday morning, July 19th – Small and clean. Swell is 3ft from the SSW, with a very long 21-second period. The wind is glassy, 5 km/h from the SSW. Water temp is 74°, normal for the season. The energy is moderate (839). It’s a slow, inconsistent wave, but it’s clean. Good for a beginner on a longboard.
Monday morning, July 20th – Same deal. 4ft SSW swell, 18-second period, glassy wind from the ESE at 5 km/h. Energy is moderate (721). Still clean, still inconsistent. A nice morning for a paddle.
From Tuesday the 21st through Saturday the 26th, it’s mostly poor. The wind turns onshore or cross-shore, the swell drops, and the surface gets chopped up. There’s a gap of about five days where you’re better off doing something else.
Sunday morning, July 26th – A pulse of swell returns. 5ft from the SSW, 11-second period, but the wind is cross from the SE at 10 km/h. It’s marginal. The afternoon gets bigger at 7ft, but the wind stays cross, so it’s lumpy and messy.
Monday July 27th is the standout. The morning delivers 7ft of SSW swell, 14-second period, with glassy wind from the NNE at 5 km/h. The energy is strong (1576). The afternoon is 6ft, still glassy with a light SE breeze. This is the best session of the window – clean, solid, and fun. It’s a bit big for beginners though.
Thursday July 30th is for experts only. Morning shows 10ft SSW swell, 16-second period, with clean cross-offshore wind from the east at 10 km/h. The energy is very strong (3820). The afternoon is 8ft with similar conditions. This is a heavy, powerful groundswell. Not for the inexperienced.
The swell fades after that. Monday August 3rd brings a return to small, clean surf: 5ft SSW swell, 11-second period, with light offshore wind. A nice, easy morning.
The best day to save your energy for is Monday July 27th – clean, solid, and glassy. The 30th is for the big-wave crew. Crowds are possible here, but with the inconsistency, it’s usually not a circus.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Nera Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
