The Lowdown

Alright, Rusty here. Let's have a look at what's coming down the line for Narrabeen-South.

Well, don't get too excited just yet. We’ve got a bit of a slow start this week, but there's some real promise tucked away in the back half of the outlook if you're patient. The first few days are a write-off, with strong cross-shore winds making a mess of things. But then things start to turn around.

Tuesday the 11th is where it starts to get interesting. The morning is only marginal with a small 4ft SW windswell and a short 6 second period, offering up a bit of weak, crumbly stuff for the loggers. But the real standout is the Tuesday afternoon session. We get a jump in size to 6ft at a long 12 seconds, pushing in from the South. That’s a proper groundswell. The wind goes light offshore from the WNW, so it should be clean and lined up. The wave energy hits a solid moderate level (962), and for an exposed beach break like Narrabeen, a long-period south swell can get a bit straight, but it’ll still offer up some proper walls. This is the pick of the week, no question. Water temp is sitting at 63°, which is about a degree and a half colder than usual for this time of year – definitely feel that little extra chill.

Wednesday the 12th is a come-down. The morning is small and weak, and by the afternoon we're down to 3ft with offshore winds, making for clean but very small, ordinary waves. Thursday the 13th bounces back with a solid 6ft Southerly swell in the morning, and light offshore SW winds again. That’s a lot of juice – over 8ft it gets expert-only, but at 6ft it’s still a good challenge for strong intermediates. The energy is moderate (795). The afternoon gets a bit funky with a cross-shore wind. Friday the 14th keeps the trend going with a clean 4ft in the morning on light offshore winds, but the afternoons are getting chopped out.

Saturday the 15th and Sunday the 16th are pretty average – small, rainy, and messy. After that, we hit a long gap. From Monday the 17th right through to the end of the week, it's just poor conditions with onshore winds and small, weak swell. A real bummer of a stretch.

Now, look ahead to Thursday the 20th. We get a morning of absolute glass, dead calm, with a small 3ft ESE swell at a 9 second period. That’s the kind of morning you drag the longboard out for some solo peeling runners. The energy is low (221), but with no wind, it’s about quality, not power.

Then Friday the 21st morning is another glass-off, this time with a bit more size at 5ft from the ENE. That’s a nice little pick-up. Still lowish energy (241), but clean as a whistle. Saturday the 22nd morning keeps the glassy theme going with a 4ft swell pushing in from the ENE, and a slightly longer 10 second period. The wave energy picks up to a moderate 339. This is another promising one. That long weekend stretch is looking like the best run of the whole outlook.

Sunday the 23rd morning is clean again with offshore flow, 4ft at 10 seconds from the ENE. But the afternoons are getting ruined by onshore seabreezes. The end of the outlook on Monday the 24th and Tuesday the 25th is nothing special, with strong offshore winds making it hard to paddle into a 5ft ENE swell on Tuesday morning.

So to sum it up: the absolute standout is Tuesday 11th afternoon. Get in the water. The second-best window is the glassy mornings from Thursday the 20th through Sunday the 23rd – perfect clean conditions for a longboard or a fish. Everything else is either too windy, too small, or a bit of a chore.

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.
