The Lowdown
Alright folks, Rusty here. Let’s get into it for Slip Point. Right off the bat, I gotta be straight with you – this 16-day window is a tough one. We’ve got a long dry spell on the horizon. For the first couple of days, through Saturday and Sunday, it’s pretty much flat or junk. The combined swell energy is next to nothing, measuring just 94 (weak) on Saturday morning, dropping to nothing by Sunday. You’re better off staying home or doing a gear swap.
Things start to look a little less bleak on Monday, July 20th. We get a bit of WNW swell rolling in at 3 ft, with a period of 8 seconds. The energy picks up to 118 (moderate), which is the best we’ll see for a while. Monday morning the wind is a light cross-offshore breeze from the east, so conditions should be clean. Then Monday afternoon, the wind goes completely glassy – dead calm, 0 mph. That’s a rare treat. The waves are still small, but if you’ve got a log, this is your window. The water temp is about average for this time of year, nothing weird to report.
Tuesday morning, July 21st, keeps the glassy theme going with a light NE breeze at 3 mph, and the swell is still hanging in there at 2 ft from the WNW. The energy is weak though, at 68. It’s small, but it’ll be clean. After that, it’s a slow fade. The swell sticks around through Wednesday and Thursday around 3 ft to 3 ft, but the wind turns onshore from the NW and WNW, making it choppy and messy. The energy climbs to 169 (moderate) on Thursday, but the wind kills it.
From Friday, July 24th, right through to the end of the run on August 2nd, we’re looking at a long stretch of poor surf. The swell gets smaller and smaller, dropping to 1 ft on the 26th (energy of just 19), and we have several days with zero wave energy at all. There are a few mornings with clean cross-offshore winds from the east, like on July 31st and August 1st, but the swell is either non-existent or too weak to bother with. It’s a real bummer. For a point break like Slip Point, we need a decent groundswell with good direction, and this just isn’t it.
If I had to point you to the only true standout, it’s Monday afternoon, July 20th. That glassy, calm wind with 3 ft of WNW swell is the closest we get to a decent session. It’s small, but it’ll be the cleanest wave of the whole forecast. After that, it’s a waiting game.
Rusty, signing off.
