The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the table for Narrabeen-South over the next couple of weeks.

We’ve got a bit of a slow start, but don’t write it off just yet. The first few days are pretty average, with small, weak surf and messy conditions. Thursday the 16th has a bit of size at 8 ft from the south, but it’s accompanied by a fresh southerly wind and a short, weak 8-second period – not exactly quality. The combined swell energy is moderate at 743. Friday the 17th is flat and tiny with a 3 ft southerly swell and a 6-second period, so really nothing to get excited about. Saturday and Sunday stay small, with waist-high waves and light winds, but the sets are short and the conditions are ordinary.

Now, here’s where it gets interesting. Monday morning, the 20th of July is a major standout. We’ve got a clean 6 ft east-northeast swell wrapping in with a 10-second period. Combined swell energy is a solid 788 – moderate but building. The wind is light west-northwest, almost offshore, keeping the waves clean. This is your best bet for quality surf that isn’t too big or too small. It’s still an exposed beach break, so look for banks.

Then, Tuesday morning, the 21st of July is another absolute cracker. Glassy conditions, light offshore from the northwest, and a solid 5 ft east-northeast swell with a 10-second period. The energy is still solid at 528. This will be clean, lined-up, and proper fun. It’s going to be a beautiful session if you can get out there.

Keep in mind, crowds are listed as “often” at Narrabeen-South, so especially on these good mornings, expect company. The water temp is sitting around 64°F, which is about what you’d expect for this time of year – no weird anomalies.

After Tuesday, the surf drops right off into tiny, weak waves through Thursday the 23rd. But hold on – Friday afternoon, the 24th of July looks huge. An 8 ft southerly swell with an 11-second period and very, very strong combined swell energy of 2883. That’s proper, powerful groundswell. A light SSE breeze keeps it clean. This is for the experienced crew only though – over 8 ft is expert territory, and the long period will make it punchy and powerful. Point breaks and reefs will handle it better than the beach, so pick your spot.

Saturday the 25th still has a 6 ft south swell, clean and offshore in the morning, but the wind picks up strong from the SSW in the arvo, so get out early. The following week looks more inconsistent, with some 4 ft to 6 ft south swells and offshore winds around the 29th and 30th. Friday morning, the 31st of July is another one to circle – glassy conditions again, a 6 ft southerly swell with moderate energy at 649, and clean, lined-up waves. This could be a proper session for those who don’t mind a bit of size.

Overall, the real standouts are Monday 20th and Tuesday 21st mornings for clean, manageable surf, and Friday 24th afternoon for big, powerful waves if you’ve got the skills.

Stay stoked, get out there when it’s good, and don’t bother paddling out when it’s rubbish.

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.
