The Lowdown
Alright, let's check out what's on offer for Slip Point. It's a bit of a slow burn, with a whole lot of nothing much before we finally get a window that’s worth paddling for.
The water is sitting at 53° right now, which is a solid 4° colder than normal for this time of year – that's a serious chill, so bring the thickest rubber you've got for Slip Point.
The first week is mostly a waste. Tiny waves from 1 to 2 feet with poor conditions for days. The best of a bad lot comes on Thursday morning the 17th with a weak 3-foot swell from the WNW, but the energy is still pathetic. It's "surfable" but nothing to get excited about. Friday morning the 18th sees similar small stuff, 3 feet from the WNW, but at least the wind goes glassy and clean – a bit of peace, but the swell is still lifeless.
Then it really goes flat. From Saturday the 19th all the way through Sunday the 27th, there are huge gaps with barely any surf. For most of a week, the energy is either gone or total junk. On Monday the 21st afternoon, a long-period 3-foot swell shows up with a 13-second interval, but it's cross-onshore and messy. The energy is decent, but the quality is poor – more of a windy mess than a rideable wave.
Now, here's the one true standout in this entire 16-day window: Tuesday morning the 22nd of September. The forecast shows a clean 4-foot swell from the west, with a period of 11 seconds. The wind is glassy, so it'll be clean. The energy jumps way up – now we're feeling some real push. This is the closest we get to a proper session. Keep in mind that 4-foot is manageable for most, and with that period, Slip Point should offer up some nice lines.
After that, the ocean goes back to sleep. We see another pulse right at the end, on Monday the 28th. Monday morning brings a 2-foot swell from the west at a very long 14 seconds, with cross-off wind. The energy is moderate, but that period is special. Then Monday afternoon cleans right up with glassy conditions on a 2-foot west swell, energy climbing even more. It’s not the size you want, but if you're on a longboard or just want to feel some glide, that afternoon glass-off will be the best you get after the 22nd.
The rest of the 29th and 30th is back to weak, short-period dribble. So to wrap it up – forget this week. Mark your calendar for the morning of the 22nd of September for your best shot, and keep an eye on the afternoon of the 28th for a clean, long-period glass-off.
