The Lowdown
Alright, this is Rusty comin' at ya from the beach. Let's have a look at what's on the menu for Narrabeen-South over the next couple of weeks.
Honestly, the first week is a bit of a grind. We've got a lot of days with onshore, cross-shore, or just messy wind, and the swell is either small or poorly directed. The water's sittin' at 63°, which is pretty much what you'd expect for this time of year, so no surprises there.
Now, there are a couple of little windows of hope. The first real standout is on Thursday, August 13th. The morning is looking good with a fresh offshore wind from the WSW, cleanin' up a solid 7ft groundswell from the SW. The energy is strong (476), and that offshore wind is a major win. It's a bit of size there, so it's more for the advanced crew. The afternoon cleans up even more, with a 8ft swell from the SSW and the energy is absolutely pumping (2217). That's a big, powerful swell, so only the experts need apply. The wind backs off to a cross-off, so the shape should be there for the best of the day.
The other standout to circle on your calendar is Friday, August 21st. This one is a bit further out, so the details could change, but it's lookin' promising. The morning is calling for perfect glassy conditions with a 3ft, 9-second swell from the ENE. The energy is moderate (213), but with zero wind, Narrabeen-South should be smooth as silk. That's a great session for a broader range of surfers, just keep an eye on the forecast as it gets closer.
Between those two highlights, it's a lot of small, messy, or blown-out surf. The swell kicks up a bit around the 15th and 16th, but the wind just isn't playing ball.
So, the pick of the lot is clearly Thursday, August 13th for the bigger, more powerful, and cleanest conditions for the advanced crew. Friday, August 21st is a real contender for a cleaner, more user-friendly session if the glassy conditions hold.
Alright, I'm signing off. This is Rusty, see you in the water.

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.
