The Lowdown
Righto, Rusty here.
Well, I've had a look at the charts and, to be honest, it's a pretty quiet one for the Nera Rivermouth. We’ve got a solid 16-day block ahead of us, but the surf is going to be a real struggle. The first proper recommendation doesn't even appear until we are well into the window, so don't expect much action for a while.
For the first few days, you're looking at tiny ripples and poor surf. The water temp is sitting at about 73°F, which is right where it should be for this time of year, but that's about the only positive. There's a gap of several days with nothing worthwhile, and even when we do see a pulse of energy, the conditions are going to be a battle.
The best chance for a paddle, and I'm using the term "best" loosely, will be around Thursday the 13th through to the 14th. The swell starts to show some life, with the combined energy picking up to moderate levels (112), but it’s breaking straight into a shelter. The swell is a small and weak 2ft from the SW. The wind is cross-on and fresh, making it choppy. It might be worth a look if you’re desperate, but it’s a beginner-level wave at best.
Later in the week, the swell gets a bit bigger, reaching 3ft on the 15th and 16th from the SSW, and the combined energy is strong (812). But here's the kicker – the wind is a moderate to fresh cross-shore breeze that’s going to wreck any chance of a clean face. The swell period is really long, like 17 seconds, so it’s a groundswell. That long period is better for a point or reef, but at a river and beach setup like Nera, it’s likely to just surge straight and close out.
Honestly, the whole outlook is a bit of a bummer. The wind is almost never off or glassy, and when we do have a glassy morning on the 20th, the swell is a pathetic 1.0ft. For the kite surfers, the moderate to fresh cross-shore wind and lumpy conditions from the 16th onwards might be more fun than a surfboard.
So, there it is. The 16-day forecast is a flat spell with a few small, wind-affected bumps. The chances for a good surf are basically zero. It tends not to stay this poor for long around here, but this stretch is a true test of patience.
Rusty.
