The Lowdown
Alright mates, Rusty here. Let’s break down what’s coming for the next couple weeks.
We’ve got swell on the way starting Thursday morning, and the real winner is right at the start. Thursday morning at Narrabeen-South is the one to circle: a 8ft south swell with a 10-second period, pumping out 1757 combined swell energy – that’s a lot of power in the water. Wind is light offshore out of the SW at 9 mph, so you’re looking at clean, lined-up waves. This is for the advanced crew only – 8ft is serious size. Water temp is 65°, pretty normal for this time of year.
Friday morning keeps it going with 7ft from the south and those same offshore breezes, energy still strong at 1451. Clean again, but still big. Saturday drops to 5ft and the wind goes cross-offshore – still surfable but not as punchy.
Sunday brings a 6ft, 12-second groundswell from the SSE, but the wind is light cross-on, so it’s not as clean. From Sunday afternoon through the middle of the following week, the swell fades and the wind gets messy. A few days there where it’s pretty flat or blown out – Tuesday through Thursday the 8th are particularly quiet.
Into the second week, the surf picks up again from Monday the 10th of August: 6ft out of the SE with 11-second period, but cross-shore wind in the morning and onshore in the afternoon, so conditions are average. Tuesday the 11th is the best of that week – 7ft from the SE, short 7-second period, but with a light cross-offshore west wind and clean conditions. Energy is 707, solid. Wednesday the 12th is also notable: 8ft from the SSE, 8-second period, clean offshore wind. Another big one for experienced surfers only.
These longer-period swells out of the south and southeast can race straight in and close out on a beach, so Narrabeen-South might get a bit walled-up on the Sunday and Monday sets. Worth checking, but don’t expect perfection.
Crowds at Narrabeen-South are likely when the surf is this good – it’s an exposed beach break and word gets around quick.
Best of the whole run? Thursday morning. Don’t miss it. Second week, Tuesday and Wednesday the 11th and 12th are promising but a bit further out, so keep an eye on the forecast. Stay safe out there.
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.
