The Lowdown
G’day, Rusty here. We’ve got a bit of a mixed bag coming up for Narrabeen-South over the next 16 days. The first few days are pretty quiet with only small, weak swells and dodgy winds, so hold your horses – it’s not until the end of the month that things really start firing.
The good stuff kicks off on Thursday, 30 July with a solid pulse of south swell. Early morning sees a clean 8ft S swell with a cross-off wind from the WSW, perfect for experienced surfers. The combined energy is pumping (1475), and the water temp is about average for this time of year. That morning session is easily the standout of the run – it’s clean, powerful, and the sets will have some grunt. Later in the afternoon, the swell drops to 7ft S, still clean, but the energy eases a bit (954).
Friday, 31 July keeps the run going with offshore winds (WSW) in the morning and a solid 6ft S swell. The energy is still strong (656) and conditions are clean. The afternoon sees the wind swing S, making it cross-off, and the swell stays steady at 6ft. It’s surfable but not quite as perfect as the morning.
Saturday, 1 August offers a more manageable 5ft S swell with light offshore SSW winds in the morning. The afternoon goes glassy with WSW winds and a 4ft SSE swell – beautiful clean conditions with moderate energy (311). Sunday, 2 August starts calm and glassy under north winds with a 3ft SSE swell, nice and clean (247), but the afternoon gets messy.
The next standout window is around Wednesday, 5 August. The morning delivers a chunky 8ft S swell with cross-off WSW winds, very strong energy (2076) – this one’s for the experienced crew only. Saturday, 8 August morning also looks promising with a 8ft SSE swell and long 12-second period, clean under cross-off WNW winds, and massive energy (1633). Just know that long-period south swells can straighten out at beach breaks, but Narrabeen-South handles it well.
Crowds are often here, so expect company on the good days. Keep an eye on that Thursday 30 July and Wednesday 5 August morning windows – they’re the real gems.
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.
