The Lowdown
Alright folks, Rusty here. Let’s talk about the next couple of weeks at Narrabeen-South.
It’s a bit of a slow start, but once we get to Friday the 4th, things start to look up. The early part of the window is pretty flat and messy, so don’t bother paddling out until then. The real standout is going to be Thursday the 10th, with a solid S swell pushing 4 feet, clean and well-shaped, and the energy in the water is impressive (944). The wind is light and offshore, so it’s going to be glassy. That’s your best bet for a proper session.
Before that, Friday the 4th morning is worth a look too. We’ve got a 4-foot S swell with a good 11-second period, and a light offshore breeze. The combined energy is moderate (409), so it’s not a monster, but it’ll be clean and fun. Sunday the 6th morning also has a similar setup, 4 feet from the S and offshore winds, but the wind is a bit stronger.
Monday the 7th morning is a beauty – glassy conditions with a 4-foot S swell. The energy is solid (329), and with the wind dead flat, it’s going to be super clean. That’s a great session for a goofy-footer.
Now, a few things to note. This is a very consistent spot, so you can usually rely on it. But it’s for advanced surfers, and crowds are often a problem. The swell direction is mainly from the S and SSE, which is just about spot-on for this break. The water temp is about average for this time of year, nothing unusual.
Thursday the 10th is the standout. I’d be getting in the water then. The 5-foot S swell on Friday the 11th morning is also a good one, but it’s a bit more exposed to the onshore in the afternoon.
Overall, the first week has a few solid windows, but don’t get too excited about the second week – it looks small and pretty average. Stay patient.
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.
