The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming our way in feet and miles per hour.
It’s a slow start, no doubt. The water is sitting around 71°, which is much warmer than normal for this time of year – you might get away with a spring suit.
The only real session to get excited about lands on Tuesday, the 18th of August. The morning is the clear winner: a clean 3ft swell out of the W with light cross-offshore winds. The energy is moderate (376). The period is a short 9 seconds, so it’ll be a bit lumpy, but there will be something to ride. Expect the usual crowd at Rincon - Rivermouth (Rincon-2), as it’s often busy when there’s any size.
Tuesday afternoon sees the swell pushing up to 4ft from the W, but the period drops to 8 seconds and the wind goes cross-shore, making it a bit choppier and less appealing.
Wednesday the 19th and Thursday the 20th are small, with 3ft to 3ft WNW swell. Winds stay light, so the surface will be clean, but the waves are just ordinary.
Then comes a long flat stretch. From Friday the 21st through to Tuesday the 26th, it’s barely a ripple – 1.0ft to 1ft with very weak energy (down to 44 at one point). Just small, surfable but forgettable slop.
The final day, Friday the 28th of August, shows a little pulse from the SSW at 2ft with an 18-second period (287 energy). The morning winds are light cross, so it’s marginal, but the afternoon cleans up with light cross-off and a decent score.
The takeaway: Tuesday morning the 18th is your only real shout this run. It won’t be classic Rincon, but it’s the best we’ve got.
Rusty.
