The Lowdown
Howdy, Rusty here. Let’s break down what’s on the cards for Narrabeen-South. This is a solid beach break that gets a good south swell, but you’ll need some patience. Water temp’s about what you’d expect for this time of year.
We start off Tuesday the 8th with a 8ft S swell (1005 combined energy) and a cross-off wind – bit messy though. Wednesday the 9th morning drops to 3ft with clean offshore wind, but it’s pretty ordinary.
Then Wednesday afternoon pumps up to 10ft S swell (1189 energy) with cross-off wind. That’s big, man – only for the experienced crew. Same story Thursday the 10th: 12ft S swell (2316 energy) in the morning, 10ft in the arvo, both clean but too heavy for most.
Friday the 11th morning is your best shot by far. We’ve got an 8ft S swell (2478 energy) with a gentle cross-off breeze keeping it glassy. That’s prime for the experienced surfer. The swell’s got a 10-second period, so it’s got plenty of grunt but won’t race you off the face. Expect a few heads in the water here – it’s a popular spot.
Friday arvo holds a 7ft S swell (757 energy) with decent conditions, then it all goes downhill. Saturday the 12th has a 5ft S swell but onshore wind – poor. Sunday and Monday drop to 3ft to 3ft with cross or onshore winds. Not worth the paddle.
Tuesday 15th through Wednesday 16th is dead – tiny waves or onshore slop. But Thursday the 17th morning gives you another window: a clean 6ft S swell (801 energy) with light offshore wind. Not huge, but clean and fun. Friday the 18th morning is glassy with a 4ft S swell (435 energy) – beautiful texture but not much push.
The last weekend (19th and 20th) sees a 7ft S swell Saturday arvo and an 8ft S swell Sunday morning, but winds are messy or too strong. Sunday arvo cleans up with a 7ft S swell and offshore wind, but it’s getting a bit tired.
So, mark your calendar: Friday 11th morning is the one to chase – solid, clean, and powerful. Thursday 17th morning is your cleaner, smaller alternative. The rest is either too big, too flat, or blown out.
Keep your eyes on the horizon.
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.
