The Lowdown
Alright, let’s talk about Slip Point. I’ll be straight with you—this 16-day window is pretty grim. The first few days are a total write-off. July 18 and 19 bring almost nothing: a tiny 2.3 ft lump on Saturday morning that’s already poor, then Sunday goes completely flat. So there’s a gap right at the start with no real surf on offer.
The only time you’ll even see a wave worth paddling for is Monday, July 20. Morning has 3.0 ft from the WNW with a short 8-second period, and the wind is light cross-offshore from the east—clean enough. Combined energy sits at 115 (moderate). By afternoon the swell drops a touch to 2.6 ft, but the wind goes glassy, NNW at 3 mph. That’s the best it gets all week, and even then the wave comment says “surfable but very ordinary.” The water is absolutely freezing—52.2°F, which is 6.1°F colder than normal for this time of year. That’s a very unusual chill, so bring a thick suit.
After Monday, it’s back to scraps. Tuesday through Thursday have a bit of swell (2.0–3.3 ft) but the wind is all onshore or cross-onshore, making for poor conditions. Late July 24 into the 25th sees another flat spell. From July 25 afternoon through the end of the month, the swell is tiny—1.0 ft to 2.0 ft max—and most of it is onshore. The last couple of days (August 1–2) are completely flat with glassy mornings but no waves.
Honestly, there’s no
