The Lowdown
Alright folks, Rusty here. Let’s talk about what’s lining up for Slip Point.
To be straight with you, the next couple of weeks are looking pretty slim. The surf is tiny and the energy is just not there. We’ve got a long stretch of small, weak swell that’s barely going to get you a ride. The best we can see is a few windows of clean, surfable but ordinary waves, but nothing that’s going to get the heart racing. The first real glimmer is on the 9th of September, but even then, it’s a stretch.
Let’s break it down. The 8th of September, Tuesday morning, you’ve got a tiny 2ft West swell rolling in with a 10-second period, but the combined energy is a measly 50. It’s clean, but honestly, it’s poor surf. The afternoon goes glassy, but still just 2ft. We’re waiting.
The 9th of September, Wednesday morning, is the first real mention of something surfable. You’ve got 2ft from the West with a 12-second period, giving a combined energy of 187. The wind is a light cross-off from the East, keeping it clean. It’s just ordinary, but it’s the best we’ve got right now. The afternoon turns onshore and messy.
Thursday the 10th and Friday the 11th are a write-off. The swell gets a little bump on the 10th to 4ft, but the period drops to a weak 8 seconds and the wind is cross-shore to onshore, making it choppy and poor. The 11th, we get flat with no energy at all.
The weekend of the 12th and 13th is similar. Saturday morning the 12th has a clean 2ft West swell with a 10-second period, energy at 70. It’s surfable, but ordinary. Sunday the 13th, the morning is glassy but only 2ft from the West with a super short 7-second period.
The rest of the week from the 14th through the 18th is a mix of flat spells or tiny, gutless 1.0ft to 2ft swells. The wind is often clean or even offshore, but there’s just no power. The standout moment in this whole stretch is actually the 20th of September. Sunday afternoon, the swell is still only 1.0ft from the WNW, but the period stretches out to a very long 12 seconds, and it’s glassy. The combined energy ticks up to 41. For a spot like this, that long-period groundswell is your best bet for a clean, peeling wave at the point, but you’ll be scratching for a wave.
The 22nd of September, Tuesday afternoon, gives a short burst of 2ft from the West with a 7-second period, and clean offshore wind from the ESE. The energy is 51. Again, it’s surfable but ordinary.
The final call is the 23rd of September, Wednesday morning. You’ve got 2ft from the West with an 11-second period, a clean cross-off wind, and the combined energy bumps up to 85. It’s the most promising of the lot, but it’s still just “surfable but ordinary.”
Overall, this is a tough forecast. The best window is probably the 23rd of September, with that cleaner, longer-period swell. But honestly, for a point break, that long period (11 seconds) is a positive, meaning it’ll shape up nicely. Expect to have the place mostly to yourself, as the crowds are only “sometimes” a factor here. The water temperature is about average for this time of year, so no surprises there.
It’s a waiting game. Keep an eye on the charts, because this blank run can’t last forever.
Rusty.
