The Lowdown
Righto, let’s have a look at what’s in store.
For Narrabeen-South (Sydney), the next couple weeks are a bit of a mixed bag, but there are some standout moments if you’re patient. The first proper session worth getting excited about is this Saturday morning, August 1st. We’re looking at a solid 1.6m SSE groundswell (about 5ft), a long 9-second period, and light 5 km/h cross-offshore winds from the WNW. The water is sitting at 18°, which is spot on average for the time of year, no weird anomaly there. The combined energy is moderate at 450, and the break is very consistent, so you’ll be in the rhythm. This is the pick of the early run – clean, punchy, and ripe for an advanced crew. Expect crowds though, as this spot often gets busy.
Come Sunday morning, the swell sticks around at 1.6m from the SSE, but the period jumps to a proper 13 seconds – that’s long-period groundswell energy. The combined energy rockets up to 1012 (strong). However, the wind turns cross-on from the north at 10 km/h, which will put a bit of texture on the face. It’s still surfable, but not as clean as Saturday. For an advanced surfer, it’s a goer, but the conditions are marginal – that long period might make the waves a bit straight on the beach, so watch the tide.
By Wednesday afternoon August 5th, we get a nice surprise. A clean 1.6m southerly swell, with 9-second period, under 20 km/h offshore WSW winds. Energy is strong at 694, and it’s offshore – meaning glassy, clean lines. That’s a very good session for those who can handle the size. It’s just under the 1.5m mark for beginner-friendly, but solid enough to get the heart pumping. Then Thursday morning August 6th keeps it going with 1.3m S swell and lighter winds.
The real standout, though, comes on Friday morning August 7th. A clean 1.9m S swell, 9-second period, under light 10 km/h offshore WSW winds. Energy is solid at 598. This is the sweet spot for the advanced surfer – not too big, not too small, with offshore glass. Crowds are likely, so get in early. This is the best on offer in the first week.
After that, things go a bit quiet through the middle of August, with a few days of small, weak swells and onshore winds. Not worth the paddle.
But hold on – the second week fires up. Wednesday afternoon August 12th sees a 2.2m S swell, short 7-second period, but with gentle 15 km/h offshore WSW wind. Energy is moderate-strong at 615. This is getting into expert territory over 2.0m, but the offshore breeze will make it clean. Then Thursday morning August 13th pushes to 2.5m SE swell, with moderate offshore wind – that’s big and burly, only for the well-prepared. Friday morning August 14th hits 3.0m from the east, with 25 km/h cross-offshore wind, energy at 1337 (very strong). The guidance says the swell is too big for this break, so unless you’re a pro on a gun, give it a miss.
Saturday and Sunday August 15th–16th keep the swell above 2.5m, with 3.0m ENE groundswell, 10-second period, and strong offshore winds. Energy is enormous, over 1500. Again, too big for Narrabeen-South – this is more for the experienced big-wave chargers at other spots. For the average punter, it’s a pass.
All up: Saturday August 1st morning and Friday August 7th morning are your top calls. The first week has cleaner conditions; the second week gets massive and is only for experts. No real gaps – there’s surf most days, but quality varies. If you’re keen, get on the early morning glass.

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.
Narrabeen-South is 3 km (2 miles) from Dee Why. If you plan a holiday in Sydney North Coast, look for hotels and other accommodation in Dee Why. Dee Why has rooms for a wide range of budgets as well as car hire and transport links.
