The Lowdown

G’day, this is Rusty.

Alright, we’re looking at Narrabeen-South for the next 16 days, and it’s a bit of a mixed bag early on. The water temp here is sitting pretty close to average for the time of year, so nothing weird going on there.

The first decent swell window kicks off on Sunday the 2nd of August. The morning’s got a clean 5ft SSE groundswell with a solid 13-second period, giving you some proper energy in the water (combined energy of 999). The wind is light cross-on from the NNW, so it’s workable, but not perfect. By the afternoon, the wind swings around to a strong NE onshore and it gets messy, so get out there early.

Monday the 3rd is a step down. The swell drops to 3ft from the SE with a period of 11 seconds, still fairly long, but the wind is cross-shore and the energy (274) is only moderate. The morning is the better bet, but it’s pretty average.

We’ve got a flat spell that starts Tuesday the 4th and runs all the way through to late Wednesday the 5th morning. Waves are tiny or non-existent, so don’t bother paddling out.

Thursday the 6th through Sunday the 9th sees the return of some S swell, with the pick being Friday the 7th morning. We’ve got 6ft S swell at 9 seconds, a decent amount of energy (465), and clean cross-off wind from the WNW. That’s your best session of the first week – good, solid waves for the advanced crowd here. Just be aware, this break can get crowded often, especially when it’s good. By the afternoon, the wind goes cross-on and kills it.

Monday the 10th afternoon gets a bit wild. A fresh offshore from the WSW is blowing into a building 6ft SSW swell, but the period is a short 7 seconds, and the whole thing feels messy and marginal.

Now, here’s the standout. Tuesday the 11th morning is the real deal for the second week. We’ve got 5ft S groundswell with a 10-second period, decent energy (588), and light cross-off winds from the WNW. The conditions are clean and the waves have shape. This is the session to circle on your calendar.

We then hit another quiet stretch from Wednesday the 12th through to Thursday the 13th afternoon, with weak, poor quality surf.

But hold onto your board – Friday the 14th and Saturday the 15th pump with massive S/SSE swell. We’re talking 10ft to 12ft at 10 to 12 seconds. The combined energy rockets up to 2910 and even over 3762. This is expert-only territory. The winds are clean, with glassy conditions Friday morning, but the size makes it too big for this break for most surfers. If you’re not a seasoned charger, sit this one out.

Sunday the 16th is a much better proposition. The swell drops to a still solid 7ft SSE at 11 seconds, with clean cross-off wind and over 1100 energy. Excellent conditions for experienced surfers. The morning session is the go, and it’s dropping through the day into a very good 6ft afternoon.

We finish off on Monday the 17th with a nice morning glass-off, 4ft SSE groundswell at 10 seconds. A gentle clean-up session to end the run.

So, the true standouts? Friday the 7th morning for a solid first week session, and Tuesday the 11th morning for a clean, powerful groundswell in the second week. Sunday the 16th morning is also a cracker for the advanced crew.

Stay stoked.

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.
