The Lowdown
Alright crew, Rusty here. Let’s talk about Rincon - Rivermouth for the next couple weeks.
Right now the water’s sitting at 70°F, and it’s 6°F warmer than usual for this time of year. That is seriously toasty – you won’t need much rubber.
The first few days are small. Thursday the 3rd we get a long-period groundswell from the SW, only 2ft, but at 18 seconds. Combined energy is weak at 245. With a clean cross-off breeze, you can find a little ride if you’re desperate, but it’s not the call.
Friday 4th and Saturday 5th stay small – 2ft to 3ft, with good periods. The mornings are a bit cross-on, hurting the shape, but afternoons clean up nicely. Nothing special, just wet.
Sunday 6th and Monday 7th are flat. Swell drops to 1ft or less, and period drops off a cliff. Energy is below 46. Don’t bother.
Here’s the one to circle. Tuesday 8th of September. We get a 4ft SSW groundswell with a 13-second period, and the combined energy is strong at 608. The wind is light and crossing offshore. This is the best of the run. The point will be lined up proper. Expect crowds, because this spot will be busy when it’s like this.
Wednesday 9th is still good with 3ft to 4ft SSW swell at 12 seconds, clean again. Energy is moderate at 425-446. A solid backup day.
Then there’s a gap. Thursday 10th is blown out by a 20 km/h SE wind. Friday 11th morning cleans up with 2ft SW swell, but the afternoon fades. Saturday 12th afternoon has a weird 4ft W swell with a 6-second period – short and fat, but at least the wind is off.
The second week gets quieter. Sunday 13th through Tuesday 15th is mostly waist-high or smaller, with messy wind mornings. The interesting wildcard is Thursday 17th and Friday 18th. A super long-period SW swell at 20-22 seconds starts showing, but it’s only 1ft to 2ft. The energy is moderate (202-245). That kind of period can really wrap into a point, so the afternoon sessions could surprise. It’s far out, so less reliable, but worth a look.
The clear winner is Tuesday 8th and Wednesday 9th. Get on it.
Rusty, out.
