Narrabeen-South Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks at Narrabeen-South are a bit of a mixed bag, but there’s a solid window of proper surf coming up if you know when to paddle out. The water’s sitting at about 65°F, which is pretty normal for this time of year.

The action kicks off on Thursday, 30 July. Thursday morning is the standout. We’ve got a solid 8ft south swell rolling in with a 10-second period, and the wind is offshore from the WSW at 15 mph. That’s clean, lined-up waves with plenty of push. The combined energy is pumping hard at 1623 (moderate to strong), so this is proper groundswell. For the advanced crew, this is your window. Just keep in mind that with a 10-second period, the sets will have a bit of weight behind them, and it’s an exposed beach break, so it’ll be a handful. Crowds are often, so expect some company.

Friday, 31 July morning, keeps the run going. Another south swell, 6ft, 10-second period, with offshore SSW wind at 12 mph. Moderate offshore and clean, with combined energy at 689 (moderate). It’s a notch down from Thursday but still very good. Friday afternoon sees the wind swing cross-off from the SSE, and the swell bumps up to 7ft, but it’s a bit more marginal under questionable tide.

Saturday, 1 August morning, is another good one. A 6ft SSE swell with a 10-second period, light offshore SSW breeze at 6 mph, and combined energy of 661 (moderate). The conditions are clean and the swell is consistent. This is a solid option for the weekend.

After Saturday, the surf drops off. Sunday, 2 August, has a 6ft SSE swell with a 12-second period, but the wind is cross-on from the north, and by the afternoon it’s onshore from the NE at 16 mph. That’s a write-off. Monday, 3 August, is small and weak, with a brief glassy patch in the afternoon – 3ft and 9-second period, pretty ordinary. Then from Tuesday, 4 August, through to Sunday, 9 August, it’s mostly flat or junk. Tiny swells, poor wind, and a lot of onshore slop. Combined energy values hover around 50 to 328 (weak to low moderate). There’s a gap of about five days with nothing worth paddling out for.

The next possible window appears around Monday, 10 August, but it’s a messy one. A 6ft NE swell with a short 7-second period, and onshore NNE wind at 9 mph. That’s windswell, lumpy and unappealing. Tuesday, 11 August, and Wednesday, 12 August, are similar – onshore winds and mostly poor conditions. Wednesday morning has a 6ft south swell with a 9-second period, but with onshore NE wind at 19 mph, it’s a no-go for paddle surfing – that setup looks more interesting for kite surfing.

Thursday, 13 August, offers a last glimpse. A 5ft south swell with an 11-second period, cross-on wind from the north at 6 mph. Combined energy at 662 (moderate). It’s marginal, but with that longer period, the waves might have a bit more shape. The onshore component in the afternoon from ENE at 12 mph kills it though.

So, if you’re looking for the best on offer, lock in Thursday, 30 July morning, and Saturday, 1 August morning. Friday morning is also worth it. The rest is a wait-and-see game. Forecasts can change, so keep an eye on the wind.

Rusty.
