The Lowdown
Righto, let’s have a look at what’s on the cards for the next wee while. Narrabeen-South is our spot, a very consistent, exposed beach break that handles a south-east swell best. It’s a pretty tough wave for the most part, so it’s one for the advanced crew.
We’re starting off real quiet. The first few days are a bit of a write-off, with barely a ripple. But hold on, because Wednesday the 15th of July morning is where it all kicks off. A solid 8 ft south swell, period of 10 seconds, and a clean, offshore wind from the SSW. That’s got some serious grunt – massive wave energy (1292) pumping through. This is proper, heavy, expert-only territory. The water temp is sitting around 64°F, which is pretty much bang on average for this time of year, so nothing unusual there.
The swell hangs around through Wednesday afternoon and Thursday, but the wind turns a bit scratchy, going cross-off and cross, making it more of a battle. The energy is still considerable (1016, 582, 695), but the quality drops off a cliff. By Friday the 17th, we’re down to small, ordinary 3 ft waves with weak energy (106), and we stay in a bit of a lull over the weekend. There’s a slight bump on Sunday the 19th morning with a 5 ft swell from the ENE, giving nice energy (633) and clean conditions, so that’s a decent look, but not a stand-out.
Now, the real standout window opens up on Monday the 20th of July. The afternoon session is glassy – dead calm with the wind from the ESE at just 3 mph, and a clean 5 ft swell from the ENE with a solid 10-second period. The energy is strong (676), and it’s going to be absolutely clean. That’s the pick of the first week. Tuesday and Wednesday mornings also offer glassy, clean windows with 5 ft and 5 ft swell, but the energy is a touch lower.
The second week brings a promising, but less certain, pulse. Thursday the 23rd of July morning is a cracker: 6 ft east swell, 11-second period, and a clean offshore wind from the WSW. That’s proper power (810) and shape. The afternoon holds up well too. The following days are mixed, with a lot of onshore wind and rain making a mess of things right through the weekend and into the start of the new week. The energy is still there, but the wind is going to trash it. By Tuesday the 28th and Wednesday the 29th, the swell drops back to 4 ft and 3 ft with clean conditions, but it’s small and weak.
So, if you’re an experienced surfer, the absolute best bet is Wednesday the 15th of July morning for that big, powerful, clean south swell. For a more manageable, but still excellent, wave, the Monday the 20th of July afternoon glass-off is your golden ticket. The long-range stuff on the 23rd is worth keeping an eye on, but it’s a bit further out.

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.

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.
