Narrabeen-South Surf Forecast and Surf Report

G’day, Rusty here.

We’ve got a bit of a mix coming our way for the next couple of weeks. The first few days are a write-off for any decent surf, thanks to onshore winds and weak swell. But don’t write it off completely, because there’s a real standout session on Saturday 12th September that looks like the pick of the whole period if you can get out early.

The real story here is Narrabeen-South. The water’s sitting at 64°, which is pretty much normal for this time of year, so no surprises there.

Let’s start with the good news. Saturday morning, September 12th, is where it’s at. It’s glassy with a light NNE breeze of 3 mph. We’ve got a solid 4 ft south swell rolling in with a 12-second period, and the combined energy is right in the sweet spot at 621 (moderate). The wave comment says it all: “expect very good surf conditions”. This is your standout window—clean, punchy, and the reefs and points should handle that south swell beautifully. Get it early, because by Saturday afternoon the wind swings ENE onshore at 12 mph and it’s game over.

Sunday and Monday are a write-off. Onshore winds and tiny swell. Tuesday morning the 15th offers a little hope with a clean 3 ft wave under a 12 mph SW offshore, but it’s ordinary at best. That run of poor conditions lasts until Wednesday the 16th, when things get interesting—but not for the faint-hearted. Wednesday morning through Thursday afternoon sees a big pulse of south swell hitting 10 ft to 15 ft, with combined energy readings north of 1,900 (strong) and peaking at 4,108 (very strong). The winds are cross-off and clean, but the commentary warns this is simply too big for Narrabeen-South. This is expert-only territory, and honestly, it might be more suited to a jet ski than a paddle board.

Friday the 18th and Saturday the 19th mornings both offer clean windows again, with light winds and a fading 5 ft to 5 ft ESE swell. The period hangs around 11 seconds, so plenty of shape. Saturday morning 19th is particularly promising with glassy conditions and 5 ft swell (combined energy 573 – moderate). But you’ve got to be up early; the afternoons get blown out by onshores.

Then we hit another lull. From Sunday 20th through Monday 21st it’s tiny—under 3 ft and poor. Things ramp up again on Tuesday 22nd September with another big south swell (12 ft, combined energy 2,127), but again, too big for this spot. Into the last week of the month we’re back to weak, wind-affected surf under 3 ft, with only the occasional clean but tiny window on Friday 25th (SW offshore at 19 mph but only 2 ft).

A couple of the Saturday sessions (12th and 19th) are true standouts for clean, fun size waves. The 12th is the clear winner. Also, keep an eye on Wednesday 16th and Tuesday 22nd if you’re an experienced charger with plenty of paddle fitness—it’s big and clean, but only if you know what you’re doing.

Rusty.
