The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Slip Point.
It’s a quiet start, I’m not gonna lie. For the first week or so, we’ve got tiny, weak swell and not much to get excited about. The water is running at a chilly 53°, which is a solid 5° colder than normal for this time of year, so you’ll want a thick suit.
The first real glimmer of hope comes on Thursday, September 17th. The morning shows a clean 3ft swell from the WNW with a period of 9 seconds, and the combined energy is a moderate 106. The wind is light and cross-offshore from the ESE, so it should be clean. It’s not pumping, but it’s surfable.
The real standout, the one that has me feeling a bit emotional, is the morning of Wednesday, September 23rd. We’ve got a 3ft groundswell rolling in from the west with a nice long 12-second period. The combined energy is a solid 299, and it’s glassy with the wind from the NNW. For a point break like Slip Point, that long period will mean some real nice, lined-up waves. The size is manageable, not too big for most, and the conditions look prime. This is the best session on offer.
The afternoon before that, on Tuesday, September 22nd, also has potential with a 4ft swell from the west, but the period is a very long 14 seconds and the energy is strong at 529. That long period could make things a bit straight at a point break, but it's worth watching the tides.
Thursday, September 24th morning sees another pulse of 4ft west swell with a 11-second period and strong energy of 418, but the wind is cross-onshore, so it won't be as clean as the 23rd.
After that, it drops right off again into the final days of the outlook. A few small, clean windows pop up here and there, but nothing to write home about.
So, to sum it up: a slow start, but hang in there. The morning of September 23rd is your best bet for a classic, glassy session at Slip Point.
