Narrabeen-South Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s get straight into it for Narrabeen-South. The next 16 days have a bit of a slow start, but there’s a solid window of quality surf building from Monday morning, September 7th, through to the following Saturday. The early days are pretty average or flat, so hang tight.

Alright, the first chance of anything decent lands Monday morning, September 7th. We’ve got a 5ft south swell pushing in with a period of 8 seconds, and the wind is glassy, dead calm – that’s a major positive. The wave energy is moderate (344), and the break is super consistent here. It’s an exposed south-facing bank, so that swell direction works well. This is the first real standout: clean, glassy conditions, shoulder-high sets, and the break is very consistent. Crowds are often a factor here, so expect company. This is your best bet for the Monday morning session.

Monday afternoon turns choppy as the wind swings cross-onshore, so bag the morning.

Tuesday morning, September 8th, is another standout. Swell jumps to 8ft from the SSE, period 9 seconds – that’s solid, with strong wave energy (872). The wind is a clean cross-offshore breeze, so the surf will be well-shaped. For advanced surfers, this is pumping. It’s getting big for beginners though – over 5ft – so leave this for the experienced crew. Tuesday afternoon gets messy with cross-onshore wind, but the morning is the go.

Wednesday morning, September 9th, offers a cleaner drop back to 5ft from the SSE with offshore wind. It’s a more manageable size, good for a wider range. The energy is moderate (324). It’s a solid session, but not the top pick.

Thursday morning, September 10th, sees a strong 8ft south swell with a 9-second period, and wave energy is up to 1056 – that’s very strong. The wind is cross-offshore, keeping it clean. This is for experts only – over 8ft and powerful. The period is moderate, so it’ll have some punch but not be too straight. Another standout for the advanced crew.

The following Saturday morning, September 12th, is a hidden gem. Swell drops to 4ft from the south, but the period stretches to 10 seconds, and the wind is light cross-offshore. The wave energy is still moderate (496), and the conditions are described as “very good.” It’s a smaller, clean day, perfect for a fun session without the crowd pressure if you’re early. Not a huge standout, but a nice option.

From Sunday, September 13th, things get more inconsistent and less reliable. The swell drops off, periods get long (18 seconds on Sunday morning), which can make the break close out at a beach setup like this. Wind becomes cross-onshore or onshore, and the surf quality fades. There’s a 2-3 day gap from around September 14th where the recommendations are poor or marginal, then a few small, clean windows pop up, but nothing worth getting excited about.

The water temperature is about average for the time of year – no big anomaly to report.

Overall, the standout sessions are Monday morning, September 7th, and Tuesday morning, September 8th, with Thursday morning, September 10th, for the experts. The rest of the run is quiet, but that first week has some fire.

Rusty.
