The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' for Slip Point.
Well, I gotta be straight with you – this is one of those tough outlooks where Mother Nature just isn’t playing ball. We’re looking at a full 16-day window starting now, and honestly, there isn’t a single day in there that I’d call a proper surf. It’s a total bust for the paddle crew.
We start off with a flat spell. The first couple of days are showing zero energy—combined swell energy is just 0 – and we’ve got onshore winds from the NNW and NW making a mess of things. The water is sitting at a chilly 53°, which is a massive 6° colder than normal for this time of year. That much of a temperature anomaly is very unusual, so bring a thick suit if you're even thinking about it, but honestly, there's nothing to ride.
There’s a tiny pulse of energy on Tuesday the 18th afternoon with combined energy of 125, giving us a weak 2 ft from the west with a nice 13-second period. That's a proper groundswell period, which would normally be great for a point break like Slip Point, especially with its WNW optimum direction. But the wind is cross-onshore from the WNW, so it’ll be bumpy and small. That's still "poor surf conditions."
We see a few more of these little blips. On the 22nd, a 2 ft to 2 ft west swell with 9-second period pops up, but again cross-onshore winds ruin it, giving us a choppy mess and combined energy of only 64 to 76. On the 28th, there's another 2 ft west swell but with a short 8-second period and onshore winds—just not worth the drive. The pattern is the same all the way through to the end of the month: tiny, weak swells with crummy wind directions.
There were a handful of mornings, like the 19th, 20th, and 24th, where winds went light and cross-offshore, leaving the surface clean. But with zero swell on those days, it was flat calm. Glassy, but flat.
So there you have it. Nothing on offer for us. Slip Point is completely shut down for the foreseeable future. For a spot that's fairly exposed, it tends not to stay this quiet forever, and forecasts can change, but this run is looking pretty solid. Definitely not a place for beginners—there’s no waves anyway—and even if there was, it’s an advanced spot. This setup looks more interesting for a kayak than a surfboard right now. Keep your stick on the rack.
Stay patient, gang.
