Alright, Rusty here. Let’s talk about what’s coming at Narrabeen-South. The water’s sitting right around 66°, which is average for this time of year.
The first chance to get wet kicks off Saturday morning, July 4th. We’ve got a clean 5ft swell out of the south with a 12-second period and a light 6 mph cross-offshore breeze. The energy is moderate (546), and conditions are looking real good. It’s a solid start.
Saturday afternoon drops off to a weaker 3ft south swell with a cross-shore wind. Forget the arvo.
Sunday July 5th gets hefty. A big 12ft S swell hits Sunday morning with a fresh 19 mph cross-offshore breeze. The energy is strong (2517). But that’s way too big for this spot. Afternoon stays big and clean but still too much. Experts only.
Monday July 6th eases to 8ft from the SSE with a 10-second period. Moderate breeze, clean, but marginal.
Tuesday July 7th is the standout. Morning sees an 8ft SSE swell with an offshore 16 mph wind from the SSW. The energy is solid (1476) and it’s clean. Excellent for experienced surfers. The long period (10 secs) means good shape but longer waits between sets. Crowds are often around, so expect some company. This is the pick of the week.
Tuesday afternoon jumps over 10ft, too big again.
Wednesday July 8th stays big and clean in the morning but still too large. The afternoon drops but is marginal.
Thursday July 9th is another top call for the experienced crew. 8ft SSE swell, offshore 13 mph SSW wind. Clean, consistent, excellent. The swell direction matches the optimum (SE) nicely.
Friday July 10th is a bit smaller at 8ft, but Friday afternoon is the real gem: 7ft SSE swell with glassy conditions and a 3 mph SE wind. About as clean as it gets. Excellent surf.
Saturday July 11th morning is still decent at 5ft, but the afternoon goes onshore and drops off.
From Sunday July 12th through Monday July 13th, it gets small and weak. Poor conditions.
Then from Tuesday July 14th through the 19th, another massive pulse hits. Swells between 8ft and 13ft, often clean or offshore. Almost every session is too big for this break. The energy values are huge (over 3000 in some cases). That’s kite-surfing territory, not paddle surfing.
So, the best bet is Tuesday July 7th morning and Thursday July 9th through Friday July 10th afternoon. Tuesday is the standout for experienced surfers, and Friday afternoon is the glassy gem.
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.
