The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this Nera Rivermouth outlook is a tough one. The whole 16-day window is looking pretty grim. Honestly, there's not a single session that I'd call a standout, and more than a few days where you're better off doing something else.
Right now, the place is a write-off. The wind is howling at 19 mph out of the southeast, which is a messy cross-onshore direction for this spot. The water is a warm 73°, which is about average for this time of year, nothing to get excited about. The swell is small and weak. The combined energy is moderate (299) on Saturday morning, but it's all wasted by that wind.
We're looking at a long, dry spell. After that first poor Saturday, the surf drops off a cliff. Through Sunday, the 2nd, there's literally zero swell showing. Monday the 3rd of August is a non-event, and Tuesday the 4th sees a little bump in combined energy (415-491) but the swell is still tiny and the wind is cross-shore. It's just not doing anything.
By Wednesday the 5th, the morning is clean with a light breeze, but the swell is a pathetic 3 ft from the SSW. It's surfable, but you'd be scraping for scraps. The period is 16 seconds, which is a long-period groundswell, but it's just too small for this river mouth setup to do anything with it. The combined energy is moderate (291). It's the best the window offers, but that's not saying much.
From the 6th of August onwards, it's all downhill. The swell drops to below 2 ft, and the combined energy falls into the double digits (as low as 8). The wind is light, but there's nothing to ride. We get a few glassy mornings on the 8th, 12th, and 13th, but the swell is non-existent. Even the longer period swells (up to 22 seconds) can't save it because there's no height behind them. This break is inconsistent at the best of times, and we're in the middle of a flat spell. For a beginner spot, this isn't going to help anyone learn. Forget the paddle; you'd be better off with a kite if the wind picks up, but even then, the swell is too small.
So, the honest truth? There's nothing to recommend here. The forecasts change, and it can't stay this poor forever, but for the next two weeks, Nera Rivermouth is off the cards.
Rusty.
