The Lowdown
Alright folks, Rusty here. Gonna level with ya – the next couple of weeks are a bit of a test of patience. The main story is a long stretch of tiny, weak swell. We’re looking at a solid gap here with nothing really worth paddling out for from the start through to about the middle of next week. The first day showing any promise at all doesn't roll around until Friday, August 14th.
So, for this first stretch, Rincon - Rivermouth sees a lot of small, short-period SW swell, mostly in the 1ft to 2ft range, with energy readings barely cracking three digits (maxing out around 210). The winds are often cross or cross-off, but the wave size just isn't there. It’s a waiting game.
Things finally start to show a pulse on Friday afternoon, August 14th. We’ve got a 2ft SSW groundswell rolling in with a nice long 18-second period. The combined energy jumps to a moderate 296, and with a light WSW cross-off breeze, it’ll be clean. This is the first real sign of life, but it’s still small.
The standout in this whole outlook is Saturday morning, August 15th. Overnight we pick up a little more size, with a 2ft SSW swell (16-second period) and the combined energy reading 236. The kicker? Light SW offshore winds and a cross-off direction – glassy conditions for a point break. This is the pick of the window. It’s a classic Rivermouth setup: a long-period groundswell from the SSW, perfectly groomed by offshore wind.
The water temp is sitting at a balmy 70°, which is a massive 7° above normal – that’s very unusual for this time of year and feels more like a tropical lagoon than a typical August.
Sunday morning, August 16th, holds similar potential. Another 2ft SSW swell (15-second period) with light offshore SW winds (215 combined energy). A solid follow-up day, just slightly less period than Saturday.
After that, the last few days of the window (August 17th onwards) go a bit flat and ordinary again. The swell direction stays in the SSW/SW, but the size drops and the winds get a bit messy.
So for the real dog in this fight, aim for Saturday morning, August 15th at the Rivermouth. Clean, offshore, and the best swell energy of the whole forecast. Bring a groveler though, we aren't getting barrelled.
Rusty.
