Narrabeen-South Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a look at what’s on offer at Narrabeen-South.

We’ve got a bit of a mixed bag coming up over the next sixteen days. The good news is there’s a real window of quality surf to kick things off, but it tightens up quickly after the weekend. The first few days are the clear standouts.

Wednesday morning kicks off with a modest 3ft southerly swell, but it’s a short period wind swell at 8 seconds. The water’s sitting at 64°, which is pretty much bang on average for this time of year. The wind is a clean offshore from the SSW at 12 mph, so the lines will be tidy. Combined wave energy is moderate (191). It’s surfable, but it’s not the main event.

The real action starts Thursday morning. We’ve got a solid 8ft southerly swell pumping in, with a period bumping up to 9 seconds, putting the combined energy into strong territory (1027). That’s a lot of power. The wind is a clean offshore from the SSW at 12 mph again. This is excellent surf for experienced surfers – the size is well into the over 5ft range, so it’s not for beginners. The swell direction is S, which is a touch off the optimum SE, but the quality and conditions make this the standout morning of the forecast.

Friday morning still holds great conditions with a 6ft south swell, a 10-second period, and a light offshore from the SW at 6 mph. Combined energy is still strong (637). It’s not as big as Thursday, but the shape will be nice and clean. Saturday morning delivers a glassy 4ft south swell, with a longer 12-second period, and a light northerly breeze at 3 mph. The glassy wind is a major positive – the surface will be like a mirror. The longer period means more energy in the water, but at a beach break, it can sometimes make the waves a bit straight. Still, with the glassy conditions, it’s a proper session.

From Saturday afternoon onwards, the story changes. The swell drops, and the wind turns onshore or cross-shore, bringing poor surf conditions for days. Sunday through Wednesday of the second week are a write-off with tiny waves and onshore slop. There’s a brief flicker on Thursday the 17th September morning with a 4ft south swell and a light offshore, but the combined energy is moderate (267) and the period is short at 8 seconds. It’s just a marginal window.

The rest of the outlook into the second week is pretty grim – small, weak, and messy. The only real chance of a decent wave is that Thursday morning, and even then, it’s nothing special. For a spot that’s very consistent, this run of flat days is a bit of a bummer, but it won’t last forever.

So, the best on offer is hands down Thursday morning, 10th September, with that 8ft south swell and clean offshore wind. Saturday morning, 12th September, is a close second for the glassy conditions, even if the swell is smaller. If you’re a confident surfer, Thursday is your call. If you want a smoother, more relaxed session, Saturday morning’s glass might be the one.
