The Lowdown
G'day, I'm Rusty, and I've been watching this stretch of coast for a long time. We've got a solid run of surf coming up, but you've got to pick your moments. The water temp is sitting right around average for this time of year, so a steamer is a good call, but nothing unusual.
Let's kick things off with Monday the 20th. That's our first real standout. Narrabeen-South is looking like a ripper. We've got a clean 6 ft swell coming from the ENE, with a long period of 11 seconds, giving it some real push. The wind is a light cross-offshore from the WNW at 3 mph, keeping the surface glassy. The combined swell energy is a solid moderate 1016, so there's plenty of juice. This is for the experienced crew though – that size and period will be a handful for beginners.
The quality drops off a bit through Tuesday and Wednesday, with the swell easing down to 5 ft and then 4 ft, and the wind shifting onshore. The energy drops too, down into the 200s to 500s. It's not a write-off, but it's not the kind of day you'd set the alarm for.
Now, hold onto your board, because Thursday the 24th afternoon is a belter. The wind goes completely glassy, and we've got a clean 5 ft swell from the south at 11 seconds. That's a nice, long-period groundswell, and it's packing a moderate 580 energy. The surface will be like a mirror. This is a real gem for the experienced surfer.
Saturday the 26th morning is a big one, but it's for experts only. We're looking at a solid 7 ft swell from the south, with a moderate offshore wind from the SSW at 12 mph. The combined energy is a massive 1626, which is very strong. This is a powerful, clean swell, but it's big and it's a beach break, so leave the mini-mal at home.
Another one to circle is Friday the 31st of July afternoon. The swell is back to 5 ft from the south, with a gentle offshore wind from the SW. The energy is a healthy 607, and it's looking clean with a period of 9 seconds. A very good shout for the experienced.
Now, the first of August brings a big pulse. Saturday morning and afternoon see a 10 ft south swell, with a combined energy of 1731 and 1893. That's a huge, powerful swell. The winds are favorable, but the forecast is clear: this is too big for Narrabeen-South. Only the absolute top-level experts should even think about it, and even then, it's a risk.
Sunday the 2nd of August still has an 8 ft to 10 ft swell, again too big for the average surfer. The energy is still off the charts. This is a big, powerful, and potentially dangerous run. The best bet for the experienced crew is the Monday the 20th morning, the Thursday the 24th afternoon, and the Friday the 31st of July afternoon. Those are your standouts.
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.
