The Lowdown
Alright, Rusty here. Let's take a look at what we've got for Slip Point.
To be straight up with you, this outlook is a tough one. For the most part, the surf is pretty flat or real weak. We’re sitting through a long dry spell for most of the first week and into the second. The first few days are a write-off with no swell to speak of, just a lot of poor conditions and onshore breezes. You're looking at about a week of this before something even surfable shows up.
Things finally start looking a little promising on the morning of Friday, September 4th. We’ve got a modest 4ft swell rolling in from the west with a period of 10 seconds. The combined swell energy is moderate (226). The wind is offshore from the east, which is exactly what we want to hear for Slip Point. It’s going to be clean. It’s not going to be huge, but for this stretch, this is your standout moment. That Friday afternoon cleans up even more with glassy conditions and a 3ft west-northwest swell. This is the best on offer, hands down. For the advanced crew, it's something to get wet for.
After Saturday, it drops right back off. There’s a small, long-period groundswell on Sunday, September 6th, with a 13-second period from the west. That kind of period usually means better shape and more energy, but at just 2ft, it’s barely there. The morning is clean with an east-southeast offshore wind, so the conditions will be nice even if the waves aren't. The energy is moderate (113).
The following week stays small. There are a few more mornings with clean offshore winds and tiny west swells, but nothing really gets going until the afternoon of Wednesday, September 9th. That’s the other one that’s worth a mention. We get a clean, moderate offshore wind from the east-southeast with a 2ft west swell. The period jumps up to 14 seconds, which is a very long groundswell. The energy is moderate (205). For a point break like this, that long period could set up some nice lines, but it's still small. It’s a promising long-range call, but far from a sure thing.
In short, don't get your hopes up for the next week. Keep an eye on that morning of Friday, September 4th and the afternoon of Wednesday the 9th for the cleanest, most rideable conditions.
Rusty.
