The Lowdown
Alright, Rusty here. Let's chew the fat on what Narrabeen-South is serving up for the next couple of weeks.
First off, the water temp is a steady 64°, right where it should be for this time of year. No surprises.
We've got a solid run of surf kicking off this Friday, the 24th of July. Friday morning is the pick of the early days. We're looking at clean 7ft south swell, with a period of 9 seconds, and a stiff 12 mph offshore wind from the southwest. The wave energy is pumping – you can feel it at 1226. This is excellent, clean surf, but it's advanced territory. The swell is over 5ft, so it's a bit much for beginners. The offshore wind is a major positive, keeping things glassy. This spot is very consistent and exposed to swell, so it'll be turning on. Crowds are often here, so expect some company.
Friday afternoon the wind swings cross-onshore from the ESE, dropping the quality. The size drops a touch to 6ft, but it's a longer period groundswell at 12 seconds. The energy is still moderate at 949, but the wind makes it a bit of a messy option.
Saturday morning, the 25th, is another good one. A clean 6ft south swell, 11-second period, with a light 9 mph cross-offshore wind from the west. Clean conditions, moderate energy at 776. This is very good surf. Saturday afternoon goes glassy with a 5ft south swell, 10-second period, and a light northerly breeze. The energy drops to 408, but it’s clean and glassy – a real treat for a late session, though the quality score is lower.
Sunday morning, the 26th, sees a return of a clean 6ft south swell, 11-second period, with a 12 mph offshore wind from the WSW. That's another solid, clean session with energy at 841. Sunday afternoon fades with a cross-shore wind and a 5ft swell, which is pretty marginal.
The start of the week from Monday the 27th through to Wednesday the 30th drops right off. We get some small, weak swells, mostly under 4ft, with poor energy readings (down to 10-238). The wind is a mixed bag, but it's mostly small and unexciting. There's a little window on Thursday morning, the 30th, with a 4ft south swell and a clean cross-offshore wind, but it's a short-period 7-second swell, so it's lacking punch.
The standout in this whole outlook is clearly Sunday, the 2nd of August. Now, this is a long-range call, so it's promising but not locked in. The forecast is for a massive 16ft south swell, with a 12-second period, and the energy reading is off the charts at 6580. The wind is light and cross-offshore from the WNW. Honestly, this is going to be pumping. The catch is, the swell is way over 8ft, so this is strictly for experts only. It's predicted to be too big for the break itself, but for the experienced crew on the right equipment, it will be a day to remember. The crowds will be impossible to avoid.
The days following that, from Monday the 3rd to Thursday the 6th, the swell stays solid but drops into the 5ft to 8ft range. The wind gets messy from the ESE, making for cross-shore chop. The real gem in that second week is Thursday the 6th of August. The morning shows a clean 6ft SE swell, 10-second period, with a light southerly cross-offshore wind. Energy is a solid 1000. The afternoon gets even better: a 5ft ESE swell, but with a very long 14-second period, and the energy jumps to 1640. The wind stays light and cross-offshore. This is excellent, clean groundswell for the experienced surfer. The long period means it'll be better shaped but might break a bit straight at the beach, so pick your peak.
Friday the 7th of August is also a standout. The morning is a clean 8ft ESE swell, with a 13-second period, and a light 6 mph offshore wind from the SW. Energy is a strong 1752. The afternoon holds a clean 7ft swell with the same long period, energy at 1329. This is top-tier, clean, powerful surf for the advanced crowd.
After that, Saturday the 8th drops away to a much smaller 4ft swell, and the wind goes onshore in the afternoon, so it's a fade-out.
So, to sum it up: the first few days are good, but the real magic is waiting for the swell to blow up on the 2nd of August, and then again for that clean, long-period groundswell on the 6th and 7th. Get on it if you've got the skills.
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.
