The Lowdown
Alright, this is Rusty, and I’m looking straight at the outlook for Slip Point. Honestly, it’s a tough stretch coming up. The whole 16-day window is basically a write-off for any kind of decent surf.
We’re starting off with absolutely nothing on the board. The first hint of any wave height shows up on Saturday the 22nd with a tiny 2ft from the west, but it’s got a short period and the wind is on it. That setup is just not going to produce anything rideable. There are long gaps of flat, poor conditions. You’ll see days like Thursday the 20th and Friday the 21st with zero swell, just clean but empty water. That pattern of nothing continues right through the end of the month and into September.
The little bump we get on Sunday the 29th is a joke – a 1ft swell with a 5-second period. That’s barely a ripple. The water temperature here is 53°F with a anomaly of -6°F, so it's much colder than normal for this time of year. That’s a major factor to consider if you’re even thinking about paddling out.
Later on Thursday the 3rd of September, we see another tiny 1ft pulse, but by then the wind is howling cross-onshore at 12 mph, making it choppy and ugly. The combined wave energy never gets above 81, which is weak, and most of the time it's sitting at zero. There is simply nothing to get excited about.
For a spot like Slip Point that needs a clean WNW swell, we’re not getting the size or the right wind. The only consistent thing here is the lack of consistency. When the surf is this poor and the wind is up, this setup honestly looks more interesting for kite surfing than paddle surfing. Save your wax for another day.
Rusty.
