The Lowdown
Alright, this is Rusty coming to you straight from the beach. Let's see what we've got on the cards for the next couple of weeks.
Honestly, the next few days are looking pretty grim. We’ve got a bit of swell around, but finding a good wave is gonna be tough. The water temp is sitting right where you’d expect for this time of year, nothing out of the ordinary.
Narrabeen-South is the only game in town for the whole forecast period, so we’re stuck with it. The first decent chance doesn’t roll in until Sunday the 6th. The morning is your best bet with a clean, cross-offshore wind, a 3ft south swell and a nice 12-second period on it. The combined energy is moderate (311), so there’s some push there. It’s not huge, but it’ll be clean and rideable for the advanced crew. It gets messy in the arvo with that onshore kick.
Monday the 7th is a write-off with onshore winds all day. Then we hit a bit of a lull. Tuesday the 8th morning might fool you with glassy conditions, but it’s a weak, short-period 4ft swell from the NE (144). Not much to get excited about. The next real standout doesn’t show up until Monday the 14th. Now we’re talking. The morning is clean with a 4ft south swell, and the afternoon gets glassy with that swell bumping up to 5ft and the period stretching out to 12 seconds (639). That’s a proper groundswell setup. This is the pick of the week – clean, good energy, and it should offer up some nice lines.
Watch out for Tuesday the 15th, though. The morning swell pumps up to a solid 10ft from the south with a long 13-second period. The combined energy is massive at (2788). That’s a whole lot of ocean moving around. For Narrabeen-South, that’s going to be way too big and powerful for anyone short of an expert looking for a battle. Better suited to the pros or the kamikaze crew.
After that, the energy drops off again and we’re back to smaller, messy days with a lot of wind, rain, and even a thunderstorm risk mid-week. The window is short – that Monday the 14th is the one to circle.
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.
