Table - best surf conditions forecast for Narrabeen-South over the next 16 days.
Alright, Rusty here. Let's have a look at what's coming our way.
Things are going to be pretty quiet for the entire first week. From now through the start of the following week, there's just no real size or energy to speak of. We're looking at a solid run of small, weak surf. Don't bother paddling out for that.
The real action finally shows up on Wednesday, July 15th, but there's a catch. A big pulse of southerly swell is forecast to hit Narrabeen-South, pushing chest-to-head-high plus waves at 10ft. The combined energy is strong (1247), but this thing is just too big for this break. This one's a pass.
Now, if you're an experienced surfer, there's a standout day you need to circle. Sunday, July 19th, is your window. We've got a solid 8ft easterly groundswell with a long 11-second period. The combined energy is pumping at a very strong 1758. The big news here is the wind: absolutely dead glassy conditions in the morning. For a spot that can get crowded, that glassy surface will make for some perfect lines. This is the best on offer across the whole outlook. The water temp is sitting at 65°F, which is pretty much spot on for this time of year.
Heading into the final week, there are a few other promising windows. The morning of Tuesday, July 21st, sees a drop in size to a more manageable 5ft from the east-northeast, with a clean, gentle offshore breeze from the WSW. The following Wednesday and Thursday mornings also look clean and surfable with similar 4ft to 3ft easterly swell and light offshore winds. It won't fire like that Sunday, but it's good, clean fun.
Overall, if you can wait, that Sunday the 19th is your day. For the rest, it's small and clean but nothing to write home about.
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.
