The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Narrabeen-South over the next couple of weeks.
We’ve got a bit of a slow start, but if you’re patient, there’s some real quality waiting for you. The standout window is undeniably Sunday morning, July 26th. That’s your session. Don’t miss it.
The first couple of days are a bit of a write-off, with small, messy surf and onshore winds, but things start to turn around on Sunday. Sunday morning, July 26th, is the clear winner. We’ve got a solid 7ft south swell rolling in with a clean 11-second period, and the wind is whistling offshore from the WSW. The combined swell energy is sitting at a solid 1033 (moderate), and that offshore wind will have the faces looking like glass. This is excellent surf for experienced surfers – powerful, clean, and well-shaped. The swell is a bit much for beginners, but for anyone who knows what they’re doing, it’s game on. Expect crowds, it’s a very consistent spot.
The rest of the week is a mixed bag. Monday morning, July 27th, will drop to a 4ft south swell with a clean cross-off breeze, but it’s much smaller. Thursday afternoon, July 30th, shows some promise with a 6ft south swell, 11-second period, and a clean cross-off wind. The energy is moderate (834) and the surf should be good, but it’s not as clean as Sunday.
After that, the swell drops right off into the end of July and the first week of August. We’re looking at tiny, weak waves of 1.0ft to 2ft, mostly with poor conditions. There’s a long stretch of flatness from Monday, July 28th, right through to Friday, August 7th. It’s just not worth paddling out for most of that time.
But hold on to your board shorts, because the second weekend is looking absolutely wild. On Saturday, August 8th, we’ve got a massive 21ft SSE swell with a 12-second period. The combined energy is a whopping 12109 (very strong). The wind is offshore from the NW in the morning, swinging to a clean offshore SW in the afternoon. This is a monumental swell, but it’s way too big for this break. This is expert-only territory, and honestly, it’s probably going to be more of a spectacle than a surf session. The setup looks more interesting for kite surfing than paddle surfing. Sunday, August 9th, is still pumping with a 16ft SE swell, but again, it’s massive. Keep an eye on this one, but be smart about it. This is a long-range forecast, so it’s promising but less certain.
So, to sum it up: don’t bother until Sunday morning, July 26th. That’s your best bet. The middle of the week is a total dud, and the following weekend is for the big-wave tow crews or the kite surfers only.
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.
