The Lowdown
Alright folks, Rusty here. Let’s talk about the skinny at Slip Point.
It’s gonna be a slow few weeks, plain and simple. The first half-decent window is Friday morning, September 4th. We’ve got a clean little 2ft W swell pushing through with a 10-second period, and light cross-off winds from the east. The combined energy is a weak 90, so it’s not packing any punch, but it’s rideable. The water is a brisk 54°, which is a good 4° colder than normal for this time of year – you’ll want a thick suit and booties. Don’t expect much, just a few little rollers if you’re jonesin’.
After that, it goes totally flat and ugly for six days. The wind is mostly onshore or cross-onshore, and the scores are all zeros. Leave the boards in the rack.
Then we get a little spark on Saturday the 12th. Saturday morning shows 3ft from the WNW with a 10-second period. The combined energy finally hits 128 – still weak, but the best we’ll see. The real beauty is the wind: a light east breeze keeping it cross-off and glassy. For Slip Point, a point break that loves a WNW swell, that’s your best look. It’s not big, but the lines will be clean and you’ll get a few long rides. Longboard territory all the way.
Another big dry spell follows, with nothing until Friday the 18th. It’s the same deal: 3ft from the WNW, 9-second period, and combined energy at 110. Clean in the morning with light east winds, then glassy by the afternoon with a north-northeast breeze. It’s ordinary but you can paddle out and get wet.
The real standout is that Saturday the 12th morning session. It’s not firing, but it’s the cleanest and most consistent we’ve got. Everything else is small, weak, or blown out. Don’t plan a road trip for it.
Rusty.
