The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Narrabeen-South (Sydney) over the next couple of weeks.
First up, we've got a little bit of a wait. There's nothing really worth paddling out for until Wednesday the 22nd of July. The water temp is sitting at 64.2°F, which is pretty much bang on average for this time of year, so no surprises there.
Wednesday morning the 22nd will see some small 3.9ft ENE swell rolling in with a 10-second period. The combined swell energy is a weak 298 (moderate), but the wind is a light 6 mph cross-off from the WNW, so it'll be clean. It's a slow start, but there's a wave to be had. By Wednesday afternoon, the wind goes glassy, dead calm from the NNE at 0 mph, with the swell dropping just a touch to 3.6ft. That afternoon session will be smooth as glass, but it's still small.
Thursday the 23rd is a step down. Morning sees 3.0ft ENE swell with a 9 mph cross-off from the W, keeping it clean, but the energy is only 130 (weak). It's surfable, but ordinary. The afternoon picks up a clean offshore breeze from the WSW at 12 mph, but the swell is still small at 2.6ft. Not exactly firing.
Now, here's where it gets interesting. Friday the 24th of July is a standout. The morning brings a solid 7.5ft S swell, period 10 seconds, and the combined energy is a massive 1624 (strong). The wind is a clean offshore from the SW at 9 mph. This is excellent surf for experienced surfers – it's a bit too big for beginners. Just keep in mind, with a 10-second period, it's a mix of ground and wind swell, so it'll push through with some grunt. The afternoon sees the swell drop to 7.2ft, with a longer 12-second period and a light cross-shore breeze from the SE. It's still good, but the morning is the pick.
Saturday the 25th sees the swell ease to 5.9ft S in the morning, with a cross-off breeze from the W at 9 mph. The energy is 736 (moderate). It's a bit messy, but surfable. The afternoon gets glassy again with a 4.6ft S swell and a 3 mph WSW wind. That'll be clean and fun.
Sunday the 26th is another strong morning. We've got a 6.2ft S swell with an 11-second period, energy of 816 (strong), and a clean cross-off from the W at 9 mph. This is a very good session. The afternoon turns onshore from the NE at 6 mph, making it a bit bumpy, so get in early.
From Monday the 27th through Tuesday the 28th, the surf goes quiet. Monday morning has a weak 3.6ft S swell with a 9-second period, and the energy is only 199 (weak). By Tuesday, it's down to 1.3ft with a 34 (weak) energy. Not worth a look.
Then on Wednesday the 29th of July, we get a pulse. Morning brings a 5.6ft SSW swell, period 7 seconds (short period), with a clean offshore from the SW at 9 mph. The energy is 295 (moderate). It's a bit short period, so the waves will be a bit lumpy, but it's clean. The afternoon ramps up to a 9.8ft S swell with a 8-second period, energy 1274 (strong). But – and this is a big but – the forecast says the swell is too big for this break. This is for experts only, and even then, it's pushing the limits.
Thursday the 30th is also huge. Morning has a 9.8ft SSE swell, 9-second period, with a clean offshore from the SW at 9 mph, energy 1764 (very strong). Again, too big for this break. The afternoon is similar, 9.8ft with a cross-shore breeze. Definitely not for the faint-hearted.
Friday the 31st sees the swell drop to 5.6ft S with a long 12-second period, but the wind is a cross-onshore from the ENE at 9 mph, and there's light rain. The energy is 1077 (strong), but it's choppy. Not great.
The first week of August is a write-off. Saturday the 1st has a small 4.6ft SSE swell with a cross-shore breeze, but the afternoon is onshore. Sunday the 2nd has a tiny 3.3ft SSE swell, and
Short Range ForecastMostly dry. Warm (max 20°C on Wed afternoon, min 8°C on Thu night).

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.
