The Lowdown

Alright folks, Rusty here. Let’s just get this straight from the start: the next 16 days at Nera Rivermouth are a total write-off for surf. There’s no way around it. The forecast is littered with poor surf conditions, and I can’t find a single proper wave to recommend. We’re looking at a long, blank run from now right through to the end of the period.

The early part of the outlook, from Wednesday 5th August right through the weekend, is a sad story. We’ve got tiny swell heights, barely reaching 3 ft at best, with periods that are either too short or that long 15-second groundswell that’s just not wrapping in properly. The wind is mostly cross or cross-off, which is okay, but there’s just no energy. The combined energy readings are in the low double digits or triple digits, but the wave comment says it all – “poor surf conditions.”

Moving into the second week, the swell does pick up a bit. By Thursday 13th August, we start seeing some 4 ft to 5 ft swell from the SSW, and the combined energy jumps into the hundreds (479), but it’s all for nothing. The wind is either cross, cross-on, or onshore, and the wave comment is still “poor surf conditions.” Even on Saturday 15th August, when the swell hits 5 ft and the combined energy is a massive 1151, the wind is a 15 mph cross-shore, making it a lumpy, choppy mess. That’s an expert-only wave with a cross-chop, not a fun paddle.

The water temperature is sitting at 73°F, which is 0.5°F above normal for this time of year, so it’s about average.

Honestly, for a river and beach setup like this, with mostly SSW swell and a sheltered exposure, it’s a tough spot to score when the conditions line up wrong. This is one of those times where the forecast is just a dud. A blank run like this is more normal for this area. Keep an eye on the charts, because it tends not to stay this poor for long.

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.
