Steamer Lane-Middle Peak Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s break down what’s coming for the next couple of weeks. We start slow, but there’s some proper windows of fun on the horizon.

Right now, the surf is tiny. We’re looking at flat to near-flat conditions through the weekend. Sunday morning, 13 September, has a weak 1 ft swell from the NW with a short period of 10 seconds and next to no energy (49). A light offshore is blowing, but there’s just nothing to ride. Sunday afternoon picks up a bit to 2 ft from the SW, but it’s still poor. Expect a few days of this small, weak stuff.

Monday, 14 September, things start to turn around. We get a clean 5 ft swell from the WNW, period 9 seconds, with moderate energy (304) and a slight cross-offshore breeze in the morning. By Monday afternoon, it’s even better: 5 ft from the WNW with 9-second period and solid moderate energy (375) under a light offshore from the NNW. That’s your first real taste of rideable surf. The water temp is about average for this time of year, so nothing wild there.

Tuesday, 15 September, holds size but the conditions get a bit messy. Morning sees 5 ft from the WNW with 9 seconds and strong energy (454), but a light cross-shore breeze puts some ripples on the face. Afternoon drops to 4 ft with 8 seconds and moderate energy (202), and while it’s clean, it’s just ordinary. Not terrible, but not the standout.

The real highlight, and I mean the one to circle on your calendar, is Monday, 21 September through Tuesday, 22 September. Monday morning is glassy, dead calm, with 5 ft of WNW swell, 8-second period, and strong energy (262). Monday afternoon holds 5 ft with 8 seconds and strong energy (284) under a light cross-offshore breeze. But Tuesday, 22 September – that’s the jackpot. Glassy conditions again in the morning, 4 ft from the WNW, 9-second period, and strong energy (280). This is a classic Middle Peak (Santa Cruz) session: clean, lined-up, and consistent. Crowds are often here, but with that quality, you’ll be sharing waves with stoked locals. The swell direction matches the optimum NW, so the reef will be working beautifully.

After that, we get a bit of a drop-off Wednesday and Thursday, 23-24 September, with smaller, messier waves. But then Thursday afternoon, 24 September, delivers another spike: 4 ft from the WNW, 11-second period (longer period groundswell), and very strong energy (506) under a gentle cross-offshore breeze. That’s a powerful, clean wave. The longer period means better shape and more push, but it can make beach breaks close out – at a point break like Middle Peak, that’s a bonus.

Friday, 25 September, and Saturday, 26 September, keep the fun rolling with 4-5 ft WNW swells, glassy mornings, and clean afternoons. Consistent, good quality surf. Sunday, 27 September, fades to smaller 2 ft SW swell with a very long 16-second period – that’s a pure groundswell, best on the reef. It’ll be clean but small.

So to sum it up: the first few days are a write-off. The standout window is Monday 21 and Tuesday 22 September – glassy, solid 4-5 ft WNW, strong energy, and the reef doing what it does best. If you can only pick one session, make it Tuesday morning. The second week also has some solid pulses, particularly Thursday afternoon the 24th with that longer period groundswell.

Stay stoked, and I’ll see you in the water.

Rusty.
