The Lowdown
Alright folks, Rusty here. Let’s check out what’s doing at Slip Point.
I gotta level with you – this one’s a tough stretch. The next 16 days are looking pretty bleak for getting a wave. There’s a long, dry spell from now until the morning of Monday, August 18th, with basically nothing ridable. You’ll see a few tiny bumps on the chart, but they’re all getting chopped up by onshore wind. The energy is just pathetic. That’s a solid week or more of flat, blown-out junk.
The first real chance shows up on Monday morning, August 18th. We’ve got a 2 ft swell from the west, with a 10-second period. The wind finally goes offshore from the southeast at 9 mph, so the face will be clean. The combined energy is still weak, only 54, so don’t expect any power, but it’ll be smooth. This is a log or a funboard wave. The afternoon of the 18th goes glassy with light rain, so the evening could be even better.
After that, it’s back to flat and poor. The next little blip comes on Saturday the 23rd, with a 1 ft to 1 ft WNW swell, but the wind is cross-onshore and building, so it’ll be choppy and messy. Not worth paddling out.
The best of a bad bunch, and really the only highlight, is that Monday morning, the 18th of August. Offshore wind, west swell lining up nicely with the point, and that 10-second period will give it some shape. A point break handles that kind of energy well. Crowds are *sometimes* an issue, but on a day this small and clean, it might be quiet. The water temp is about average for this time of year.
So, hang tight through the flat spell, and if you’re keen for a session, set your alarm for the morning of Monday the 18th. It’s tiny, but it’s clean.
Rusty.
