Steamer Lane-The Slot Surf Forecast and Surf Report

G’day, Rusty here. Let’s look at what’s coming up at Steamer Lane – The Slot, just that one spot for this outlook.

So overall, we’ve got a long, drawn-out run of mostly small, playable waves but nothing that’s going to blow your mind. The first real standout doesn’t come until well into the second week. For a lot of this stretch, the trade-off is that you’ll be dealing with cross-onshore winds and only knee-to-thigh-high junk, so you’ll want to be picky about your sessions.

We kick off on Thursday, 27 August, with the afternoon looking interesting. The morning is small and cross-on, but by the afternoon we get a glassy surface, 4 ft of swell from the WNW, and a short period of 6 seconds. It’s not powerful, but the calm wind makes it clean for small waves. Combined swell energy is moderate (372).

Friday 28 August morning is the real highlight of the first week. Glassy conditions again, a super-long 17‑second period from the SSW pushing 3 ft, and a combined energy of 477 – that’s moderate, but the long period gives it shape at this reef. It’s small, but for a clean, lined-up session, this is your best bet in the first few days. The crowd factor here says “often,” so expect company.

That clean spell doesn’t last. Friday afternoon and Saturday both stiffen with cross-shore and cross-on winds in the 6–12 mph range, turning the surface bumpy. The combined energy jumps around 730 to 1028 on Saturday morning (moderate wave energy), but with cross-on winds, the quality drops. Through Sunday, Monday, and Tuesday it’s mostly small and messy with combined energy falling to 174 – 446 – weak to moderate. The swell direction stays SSW, periods gradually shortening.

Wednesday 2 September morning gives a slight uptick – 2 ft from the S at 12 seconds (period is short, so not much punch), but still cross-on. That carries into Thursday 3 September, where the morning has a clean-ish offshore wind with a 19‑second groundswell from the SSW at 2 ft (combined energy 631, moderate). That long period at this reef could produce some nice lines, but the size is small.

Friday 4 September morning is the next session that deserves a look. Swell bumps to 5 ft from the S at 11 seconds (long period), with clean offshore wind. Combined energy hits 1102 (strong wave energy). That’s the biggest swell in the outlook. At 5 ft Steamer Lane will have some proper set waves, but with this being an advanced spot and the swell a bit muscular, it’s mainly for skilled surfers. The light cross-on by afternoon chucks most of it out.

From Saturday 5 September through to Wednesday 9 September morning, we settle back into a rhythm of 3 ft to 4 ft swell from the SSW. The periods hang in the 13–18 second range, but winds are mostly cross-on or onshore. The real second standout pops on Wednesday 9 September morning: glassy conditions, 3 ft from the SSW at 18 seconds (long-period groundswell), and combined energy of 723 (moderate). The reef will hold the length, and with the glass, it’s gonna be silky. This is the best-looking session of the whole fortnight – small but super clean.

After that, Thursday 10 September and Friday 11 September drop back to 3–3 ft with onshore leanings. The outlook fades out with marginal conditions.

If you’re looking for the best of what’s on offer, point your board at Steamer Lane – The Slot on the morning of Wednesday 9 September – that smooth combo of glass and long period groundswell will bring clean, lined-up reef rides that the advanced crew will love. For something slightly bigger and punchier, Friday 4 September morning gives you 5 ft of south swell with offshore wind, but it’s a handful.

There’s a gap of no truly good surf from the afternoon of Friday 28 August right through until Wednesday 9 September morning – nearly a week of marginal to poor surf – so be patient.

Rusty.
