Narrabeen-South Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Narrabeen-South over the next couple of weeks.

Right off the bat, we’ve got a bit of a quiet start. Wednesday the 19th has a tiny 2ft ESE swell with a period of 10 seconds, and the water is sitting at 63°, which is about average for this time of year. The morning is glassy and clean, but with only 224 units of energy, it’s weak. It’s surfable for a longboard or a funboard, but nothing to get excited about. That small window closes fast as the wind swings onshore and picks up in the afternoon, killing it.

From Thursday the 20th through to the start of the following week, it’s a proper dry spell. We’re looking at a run of days with small, messy, or onshore slop. A few mornings might have a clean look, like Friday the 21st with a light offshore, but the swell is tiny and weak. This stretch is basically a write-off for any decent paddle surfing. You’d be better off doing something else.

Things start to stir on Wednesday the 26th. We get a pulse of 5ft S swell with a short 7-second period, but the wind is offshore and clean. The energy is moderate at 305, and it’s a genuine option for a surf. The 27th sees a bit more size, with 6ft S swell and a light cross-offshore wind, making for clean waves. The energy is up to 426, so there’s some push. But the afternoon both days gets wrecked by onshore winds.

Now, the standout window is the end of the month and into September. On Saturday the 29th, we’ve got an 8ft S swell hitting with a 9-second period, and a strong offshore wind. The energy is huge at 1163, but this size is getting into expert-only territory. It’s clean, but it’s big. The 30th and 31st see even more size, with 10ft to 12ft southerly swells and periods up to 11 seconds. The energy is massive, over 3000 at times, and the wind stays offshore. This is a serious groundswell, and it’s going to be powerful. For a beach break like Narrabeen-South, that long period can make it dumpy and close out, so it’s best left to the experienced crew. The 31st of August afternoon is the pick, with 8ft S swell, 11-second period, and a light offshore breeze. The energy is still high at 1395, and the conditions are excellent for those who know what they’re doing. Crowds are likely here, especially on a Sunday and Monday, so be prepared.

After that, the swell fades into the first week of September. The 2nd has a glassy morning with 4ft S swell, clean and fun for a wider range of surfers, but the energy is back down to moderate. The 3rd is tiny again.

Best bets: For the experienced surfer, the 31st of August morning and afternoon is the standout. For the average surfer, the 27th of August morning or the 2nd of September morning are your best windows for something clean and manageable.
