The Lowdown
G’day, I’m Rusty. Let’s run through what’s coming for Narrabeen-South over the next couple weeks, in feet this time.
The start is a bit flat. Thursday 23rd July has weak, messy little waves, clean but not worth paddling out for. Don’t bother. There’s a decent little gap before the good stuff shows.
First real standout hits Friday 24th July morning – a clean 7 ft south swell with a light cross-off wind, period around 10 seconds. The energy is strong (1388), and the conditions are lined up and clean. That’s advanced territory at that size, so bring your experience. Crowds are likely – this one’s worth getting up early for.
Saturday 25th July morning keeps it solid with a 6 ft south swell, still clean and rippable for strong surfers.
Sunday 26th July morning is another beauty – 6 ft south swell, clean, energy sitting at 817. If Friday’s a bit too big, Sunday morning is a great fallback.
Thursday 30th July gets wild – a 15 ft south swell with offshore wind and massive energy (9408). It’s clean but the forecast flat-out says it’s too big for this break. Expert only, and even then, be cautious. Friday 31st stays heavy at around 10 ft from the south-southeast.
The second standout is Saturday 1st August morning – the swell drops to 8 ft from the southeast, period stretches to 12 seconds, light cross-off wind, clean. Energy is still high (1492) and it’s the pick for experienced surfers after the chaos passes.
Sunday 2nd August morning still offers a clean 5 ft southeast swell for a more relaxed session. After that, it gets smaller and choppier through the first half of August. Wednesday 5th August afternoon shows a clean 8 ft swell but with shorter period – worth a look if you’re flexible.
Two clear highlights: Friday 24th July morning – big, clean, powerful. And Saturday 1st August morning – solid groundswell, clean, and still punchy. Those are your best calls.
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.
