The Lowdown
Alright folks, Rusty here. Let’s be straight with you about Slip Point. We’ve got a 16-day window, but honestly, the surf is a tough sell. The first few days are a write-off, and the whole period is a struggle to find anything worthwhile. There’s a brief, ordinary window around Wednesday the 9th, but that’s about it. The rest is mostly flat or poor conditions.
The first real pulse of energy shows up on Wednesday morning, September 9th. We’re looking at a 2ft west swell, rolling in with a 12-second period. That’s a long-period groundswell, which is good for shape, but it’s only a weak energy pulse (161). The wind is light easterly, which is a decent cross-off breeze, so it’ll be clean. The water temp is sitting at 55°, which is a bit colder than normal for this time of year. But honestly, the swell is just too small to get excited about. It’s surfable, but very ordinary.
The next day, Thursday the 10th, the swell jumps up to 4ft from the west, but the period drops to a short 8 seconds. The energy is moderate (217), but the wind swings westerly, putting it onshore and choppy. It’s not a good look. The waves will be a mess.
After that, it’s a long, painful gap. From Friday the 11th all the way through to Tuesday the 22nd, the swell is either flat or tiny, with heights barely reaching 2ft. There are a few moments of glassy, clean conditions, like on Saturday morning the 12th with a 2ft west swell, but the energy is weak (70). It’s just not enough to push any decent waves. The whole setup is a bust.
Look, you might get a knee-high wave on a glassy morning, but this stretch is a classic example of the Pacific going quiet. I wouldn’t paddle out. The best of a bad lot is that Wednesday morning, but even that’s a stretch.
Rusty.
