The Lowdown
Alright folks, Rusty here. Let's look at what's cooking for the Santa Cruz coast over the next couple of weeks.
Alright, so straight up, this isn't a classic run for Steamer Lane. We've got a long stretch of small, generally weak energy headed our way, and the winds aren't doing us any favours. The tide and conditions are going to keep things marginal for the majority of the time. The combined swell energy rarely gets into a fun range, hovering in the 200s, 300s, and low 400s for the most part, which is weak to moderate at best. You're really going to have to pick your moments.
For the first ten days, from Friday the 11th right through to the 20th, it's a real "look before you leap" situation. Most sessions are showing small cross-onshore winds, or onshore slop. The surf is tiny, mostly between 2 ft and 5 ft, and a lot of it is short-period, choppy stuff. Saturday the 12th afternoon gets crossed-out with a stiff 12 mph NW breeze, and Sunday the 13th afternoon has a 5 ft, 6-second windswell from the WNW, but it's blown out with a 16 mph cross-shore – honestly, that setup looks more interesting for kite surfing than paddle surfing.
We do finally get a couple of bright spots towards the end of the run. The first real standout is Saturday morning, the 19th of September. It's not big, just 2 ft of SSW swell, but the period is a solid 18 seconds – that’s proper long-period groundswell energy, which Steamer Lane, being a reef, will handle beautifully. The real kicker is the wind: glassy. The combined energy is still modest at 366, but clean, lined-up waves on a reef with a long period punch will be worth it. Expect manageable crowds, though it can get busy out there.
The second standout, and arguably the best of the whole 16-day window, is Saturday morning, the 20th of September. Again, it’s glassy – that’s a massive positive. The swell is 2 ft from the SSW, still holding that lovely 18-second period. The combined energy ticks up a notch to 451. At this spot, a 2 ft, 18-second groundswell with glassy conditions will have those long, clean lines reeling down the point. This is the session to circle on the calendar.
Later on, we see a bit more size arrive on Monday, the 21st of September, with the morning showing 5 ft of WNW swell. The combined energy jumps to 733, which is a moderate energy pulse. However, it's a shorter 9-second period and still a light cross-onshore. It could offer some fun, punchier waves, but it won't have the quality of those glassy mornings before it. For high-quality, clean surf, stick with the 19th and 20th.
On Friday, the 25th of September, the morning is showing glassy conditions again, with a 3 ft WNW swell having a decent 12-second period. The energy is 533. It's a bit further out, so less certain, but the signs are promising.
Keep an eye on the water temp – it's running about what you'd expect for this time of year, so you'll want a spring suit.
This is Rusty, signing off. Get out there.
