The Lowdown

Alright, let’s talk Nera Rivermouth for the next couple weeks. This break is a river-and-beach setup, sheltered, and it’s inconsistent – so don’t expect it to fire every day. Water temp is about 73.8°, pretty normal for the season. The swell is mostly coming from the SSW, close to the ideal SW direction.

We get a little opener on Monday morning, July 20. Glassy conditions, 3.6 ft of long-period SSW groundswell (18 seconds, energy 721). That’s a proper groundswell, but small. The river mouth can handle the long period, and it’s beginner-friendly, so if you’re learning, this is a nice clean window. But after that morning, it’s a long dry spell. From Monday afternoon through Saturday, July 25, there’s nothing worth paddling for – a gap of about five days with barely a wave.

Sunday, July 26 sees a pulse – 5.2 ft in the morning, but the wind is cross-shore and bumpy, so it’s messy. Energy hits 1759, but quality is marginal. Not worth chasing.

The next real opportunity is Tuesday, July 28. Morning session with 4.6 ft of SSW swell, 12-second period, cross-off wind, and clean. Energy 521 – moderate. That’s a solid session, especially if you get out early. The afternoon holds up too, same size, still clean. This is one of the better options.

Wednesday, July 29 morning is glassy again but only 3.0 ft – tiny, but if you want a glassy day, it’s there.

Thursday, July 30 afternoon sees the swell building – 4.9 ft, 15 seconds, energy 1003 – but cross-shore wind keeps it messy. Not great.

The big one is Tuesday, August 4. Both morning and afternoon are pumping with 9.8 ft of SSW groundswell, 16 seconds, clean cross-off wind, and massive energy – 4108 in the morning, 3120 in the afternoon. This is expert territory – over 8 ft, so only for experienced surfers. The long period (16s) means the river mouth could shape up well, but it’ll be powerful and inconsistent. If you’ve got the skills, this is the session to aim for. But remember, it’s a long-range forecast – less certain, but promising.

Best bets: the 28th for a clean, manageable swell, and the 4th for a serious groundswell if you’re up for a challenge. The rest of the period is mostly a write-off, with that gap in the middle. The spot is inconsistent, so a blank run isn’t unusual here,

Short Range Forecast

Mostly dry. Warm (max 23°C on Tue afternoon, min 19°C on Wed night). Winds increasing (calm on Mon morning, fresh winds from the SE by Tue night).

Days 4-6 Weather Summary

Information about the Nera Rivermouth Surf forecast

The above surf forecast table for Nera Rivermouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nera Rivermouth can be found by selecting the local surf guide option on the grey menu. Our Nera Rivermouth surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Nera Rivermouth) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
