Narrabeen-South Surf Forecast and Surf Report

Alright, Rusty here, clocking in for the local forecast. Let’s have a look at what’s coming our way.

We’ve got a bit of a slow start, but don’t let that fool you. The first real action shows up on Wednesday the 12th of August. It’s not huge, but it’s clean. Narrabeen-South is seeing a 4ft swell from the S, with a period of 10 seconds, and the water is sitting at 63°, which is a touch colder than usual for this time of year. The wind is a gentle cross-off from the W at 9 mph, so the surf is clean. The combined energy is moderate (329). It’s a solid, if modest, start for an advanced crew.

Thursday morning, the 13th, looks a bit better. The swell picks up a touch to 5ft from the SSW, but the period drops to 6 seconds, so it’s a bit short and choppy. The wind is proper offshore from the WSW at 12 mph, so it’ll be clean and lined up. The energy drops to 316. It’s surfable, but not the standout.

Now, Friday the 14th is where things get interesting. The morning is a gem. We’ve got a 4ft S swell with a 9-second period, and the wind is a light cross-off from the WSW at 6 mph. The water is clean, and the energy is 249. It’s not big, but it’s fun. The afternoon is a write-off with a cross-shore wind, so get your session in early.

The real standout, the one you’ve been waiting for, is Thursday the 21st of August. This is it. The afternoon brings a 4ft ENE swell, with a period of 10 seconds, and the wind goes glassy. A light SSW breeze at 3 mph. The combined energy jumps to 316. This is clean, glassy surf, and for a break like Narrabeen-South, that’s a rare treat. The wind is offshore and glassy, so the waves will be peeling and clean. This is the best on offer in the whole window.

The following days, from the 22nd to the 25th, offer some clean but smaller surf. Saturday the 22nd morning has a 3ft ENE swell with a 10-second period, and a light cross-off wind. It’s worth a look, but the energy is only 200. Sunday the 23rd is similar, with a 4ft ENE swell at 10 seconds, and clean conditions. The energy is 331. Not a standout, but a good, consistent run.

Now, towards the end of the window, on Thursday the 27th of August, we get a big pulse. The morning shows a 10ft S swell with a 10-second period, and the wind is offshore from the WSW at 9 mph. The combined energy is a massive 2280. This is a serious swell. But, and it’s a big but, this is a South-facing break, and that combination of size and period is going to be a lot of water. The guidance says it’s too big for this break. Unless you’re a pro, and I mean a proper pro, stay out of the water. The afternoon isn’t much better at 12ft with a shorter period. This is expert territory only.

So, to sum it up: the early part of the window is steady and clean. The 21st of August afternoon is the day to circle on the calendar. The 27th is a monster, but it’s a beast for the experienced only. The rest of the time is a bit of a mix, with some clean small days and some messy ones. Keep an eye on the wind, and you’ll find a wave.

Rusty.
