The Lowdown
Alright, Rusty here, let's break it down for Narrabeen-South in feet and degrees.
The first few days are a complete bust. Tuesday the 1st through to Saturday the 6th morning sees tiny, weak swell with poor winds. The only flicker of life is Sunday the 6th morning, with a clean 4ft south swell and light cross-off wind. It's surfable but not firing.
The big one to circle on the calendar is Wednesday the 9th morning. The swell pumps to 12ft from the south with a massive energy (2727). Light offshore wind from the west will keep it clean. This is expert only territory – anything over 8ft gets serious. The afternoon drops to 8ft but gets messy with onshore wind.
The best all-round session is Thursday the 10th morning. It's not huge at 4ft from the south, energy sits at 306, and the wind is glassy out of the WSW. Dead calm, smooth waves – perfect for a strong intermediate surfer.
From Friday the 11th onward, we're back to small and weak. A few mornings, like Sunday the 13th, give clean 3ft waves with light wind, but the energy is low (80), so it's longboard or grovel territory.
Water temp is about average for this time of year, nothing crazy.
So, the standout is Wednesday the 9th morning for the big-wave crew, and Thursday the 10th morning for the cleanest, most user-friendly session of the fortnight.
Rusty out.

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.
