Narrabeen-South Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s going on at Narrabeen-South.

The window kicks off with a bit of a mixed bag, but there’s a solid run of clean conditions early on. Saturday the 29th has some morning fun with a 4ft SSE swell and a light offshore breeze – that’s a decent start, the water temp is about average for this time of year, nothing wild. The combined energy is moderate at 401, so there’s some punch. Afternoon gets tricky with a cross-shore, so the morning is your time.

Sunday the 30th is the real standout in this first week. Glassy conditions, a light offshore from the NW, and a knee-to-waist high 3ft S swell. The period is 9 seconds, so it’s a bit short but clean as a whistle. The energy is down a bit (247) but the quality will make up for it. If you can get out, it’ll be worth it. Crowds are often around here, so expect company.

Monday the 31st drops off fast – a tiny 2ft S swell with a very long 15-second period, which can make it straighten out at a beach setup like this. Not great. The rest of the first week and into early September is pretty flat or messy, with only small, poor-quality leftovers. There’s a long gap of several days with nothing worth paddling out for.

Now, looking ahead to the second week, things get interesting but come with a warning. Tuesday the 8th of September sees a massive spike: a 12ft to 13ft S swell roars in with huge energy (2065 to 4082). That’s well over 8ft, so expert-only territory. The wind is glassy or light offshore in the morning, so it’ll look beautiful, but it’s way too big for most. Wednesday the 9th holds at 8ft to 10ft from the SSE with strong offshore winds (15-18 mph). That’s still big and punchy, with energy at 1663 to 1786, but for experienced surfers, it could be a session. Not a beginner’s wave at all.

By Thursday the 10th, the swell eases to 8ft, still with fresh offshore winds – clean but still solid. The best bet for the more average surfer in this second week is Friday the 11th morning: a 5ft SSE swell, light cross-offshore wind, and comfortable energy at 556. That’s a good, manageable size with clean conditions. The afternoon goes onshore, so hit it early.

After that, it tapers down through the weekend. Saturday the 12th afternoon has a 4ft SSE swell with light cross-offshore wind and moderate energy (325) – a solid, cruisy end to the run. Sunday the 13th drops to 3ft, clean but small.

Overall, the best on offer is Sunday the 30th for the glassy, clean conditions, and Friday the 11th for the best combo of size and cleanliness for most surfers. The big stuff on the 8th and 9th is for the experts only.
