The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Slip Point over the next couple of weeks.
Truth be told, the first week is a real struggle. We’ve got a long stretch of tiny, weak waves and messy conditions that just aren’t worth paddling out for. From Saturday the 5th right through to the morning of Wednesday the 9th, it’s mostly small stuff under 2 ft, with a lot of onshore and cross-onshore wind, and the combined energy stays low – mostly under 100 (weak). You’ll be scratching your head more than riding a wave. The water is sitting at 55°F and that’s 3°F cooler than normal for this time of year, so it’s a bit colder than usual, which is something to keep in mind even when the surf does turn on.
Now, the first real glimmer of hope comes on Wednesday morning, September 9th. We see a clean little pulse of 2 ft swell from the west at 12 seconds, with light cross-offshore winds from the ESE at 6 mph. The energy bumps up to 177 (moderate), and the conditions are clean. Still, it’s not a standout – just a sign of life.
The standout session, the one to circle on the calendar, is Friday morning, September 11th. That’s when we get a jump to 5 ft of west swell, period at 9 seconds, with a clean cross-offshore breeze from the east at 6 mph. The combined energy hits 356 (moderate), and the forecast says expect good surf conditions. For a point break like Slip Point, this is the best we’ve got. The swell direction (W) is a solid match for the optimum (WNW), and with those light winds, it should be nicely lined up. Just a heads up – this spot is rated for advanced surfers, and with 5 ft, it’s the upper end of what’s manageable for a confident intermediate, but for the true rippers, it’s going to be fun.
After that peak, it fades quickly. The energy drops back into the 100s and below, and from Tuesday the 15th onward, the swell all but disappears, with combined energy in the single digits and teens. The last few days of the forecast, from the 19th and 20th, show zero swell. So, after Friday the 11th, it’s a long, flat finish.
So, to wrap it up: don’t waste your time early on. The only real call is Friday morning, September 11th. That’s your window. Get out there, because it’s going to be a quiet spell after that.
Rusty.
