Table - best surf conditions forecast for Narrabeen-South over the next 16 days.
G'day, Rusty here. Let's have a look at what's on the cards for Narrabeen-South.
First up, it's a bit of a slow start. We've got a few days of small, messy stuff that's not really worth getting excited about. From Saturday the 11th to Tuesday the 14th, the swell is tiny and the energy is weak. Saturday morning has a little 3ft ripple from the ESE with a period of 12 seconds, but the wind is cross and the combined energy is weak at 389. It's a marginal surf forecast at best. After that, it drops right off, with swell heights falling and the energy bottoming out to just 13 on Tuesday. You're better off waiting for the real action.
Now, the first real standout is Wednesday the 15th, but it's not for the faint-hearted. We've got a solid 13ft S swell hitting the beach early, with a combined energy of 2721 – that's strong wave energy. The wind is offshore from the SSW, so it'll be clean, but this is way too big for anyone but the experts. The forecast says it's too big for this break, so unless you're a seasoned charger on a proper board, sit this one out. It's a similar story on Wednesday afternoon with 10ft, still only for the brave.
The good news is things settle down. By Thursday the 16th, the swell drops to 7ft, but it's still messy. It's not until Friday the 17th that we start to see decent surf again. The morning brings 5ft from the E with a period of 9 seconds, and the wind is cross-off from the SSE, keeping it clean. The energy is moderate at 547, and the forecast says it should be very good. That's a solid session for a strong intermediate.
But the real stand-out, the one you want to circle on the calendar, is Sunday the 19th. Glassy conditions with a light WNW wind, and a clean 8ft E swell rolling in. The period is 10 seconds, and the combined energy is a massive 2784. The forecast is calling it excellent for experienced surfers. This is the best on offer in the whole window. Monday the 20th morning is also a cracker, with the same 8ft E swell, a 12-second period, and a clean cross-off wind from the WNW. That's another top-notch session for the experienced crew.
The water temperature is sitting at 65°F, which is about 0.5°F warmer than average for this time of year, so nothing out of the ordinary for a wetsuit. Crowds are often an issue at Narrabeen-South, so expect company on these good days.
After that, we have a few more good days. Tuesday the 21st morning has a clean 8ft E swell with a 12-second period and a strong offshore wind, but it's a solid size. The 23rd of July has a 5ft E swell with a 12-second period and glassy conditions in the morning, which is a great opportunity for a cleaner, smaller day. The last decent call is on the 26th of July, with a clean 5ft E swell.
Overall, the first week is a write-off, but the second week from the 17th onwards has some true gems, especially the 19th and 20th. Lock them in.
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.
