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.
