The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Nera Rivermouth.
Honestly, mate, the next couple of weeks are a real mixed bag. The first few days are pretty grim, with no surf to speak of. You’re looking at a flat spell stretching from Saturday the 22nd right through until Monday the 24th. The water temp is around 73°F, which is about average for this time of year.
We finally see a pulse of energy arrive on Tuesday morning the 25th. Nera Rivermouth will pick up a SSW groundswell, 4ft, with a very long period of 15 seconds. That long period means more power and better shape, but at a river mouth, it can get a bit straight. Combined wave energy is moderate (776), and with a light ESE cross-offshore breeze, the conditions will be clean. It’s beginner-friendly size, too.
Wednesday the 26th still has some okay waves, with the swell easing to 4ft from the SSW, period dropping to 14 seconds. Still clean in the morning with a light cross-off breeze.
If you’re willing to wait, the standout window looks like early September. On Wednesday the 2nd of September, the swell jumps up to 5ft from the SSW, with a long period of 16 seconds. The combined energy is strong (1208). It’s got a morning cross-offshore breeze, making for clean conditions. This is likely the best on offer, but it’s still a fair way out.
Then on Thursday the 3rd of September, we get another pulse: 6ft from the SSW, period 19 seconds – that’s a very long period groundswell. The energy is strong (1927). With a light cross-offshore breeze in the morning, it will be clean. This one’s for the experienced crew, as 6ft on a long period is no joke for beginners. Keep in mind, Nera Rivermouth is inconsistent, so these pulses are a big deal.
The rest of the period is filled with cross-shore and cross-onshore winds and low-energy slop. Not worth paddling out for.
That’s the rundown. Keep your eyes on that September window.
