The Lowdown

Alright, mate, Rusty here, talking about Narrabeen-South. It’s a bit of a patchy forecast, but there are a few sessions that’ll fire.

The first real surf kicks off on Sunday, July 26. The morning session is the one: a solid 7ft south swell, with a period of 11 seconds. That’s groundswell, so it’ll have some serious shape and power. The wind is a cross-off from the WSW at 9 mph, keeping the surface clean. The combined energy is moderate (921). This is the standout for the early run – it’s got size, clean conditions, and that long period.

The afternoon fades as the wind turns onshore. The next few days are a flat spell. Monday, July 27 has a small 4ft morning with clean light winds, but it’s weak. From Tuesday, July 28 through the 29th, the swell drops to ankle-snappers. It’s a real lull for about two days.

Then the big stuff rolls in. On Thursday, July 30, the morning shows a thumping 10ft swell from the SSW with a period of 10 seconds. The wind is a clean offshore from the SW at 12 mph, and the combined energy is massive (2544). This is a big, powerful swell. But at this size, this break is only for experts – it’s too big for the average surfer. Friday, July 31 morning is the same, with another 10ft swell (2987 energy) and offshore wind. Expert territory.

The weekend of August 1 and 2 settles down. Saturday morning, August 1 has a clean 7ft south swell, offshore wind, and moderate energy (666). It’s a solid day for a confident surfer. Sunday morning, August 2 is a real highlight: a 6ft SSE groundswell with a period of 11 seconds, a very light cross-off wind from the west at 6 mph, and combined energy of 996. The wind is very light, making it glassy, and the long period means the waves will have real shape. This is the best on offer for the cleaner, more manageable size.

After that, the surf drops off again. There’s a gap of poor conditions from August 3 to the 5th, with small, weak swells and onshore winds. August 6 brings a 6ft south swell, but it’s wind-affected with a short period of 8 seconds, making it messy. The energy is moderate (465), but the rain and strong wind don’t help.

The last hope is Sunday, August 9. The morning shows a 3ft SSE swell, a period of 10 seconds, and a light offshore wind from the WSW at 6 mph. Clean conditions and a combined energy of 332. It’s not huge, but it’s a clean, fun size.

So, for the standouts: Sunday, July 26 morning is the pick for the first week – good size, clean, and punchy. Sunday, August 2 morning is the second standout, with that glassy, long-period groundswell. Remember, the bigger days on the 30th and 31st are for the hardcore crew only.

Rusty.

Information about the Narrabeen-South Surf forecast

The above surf forecast table for Narrabeen-South provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Narrabeen-South can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-South surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Narrabeen-South) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Narrabeen-South may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
