The Lowdown

Alright folks, Rusty here. Let's have a look at what's cooking for Narrabeen-South over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of sessions that are gonna make it all worthwhile.

The early part of the outlook is pretty ordinary, honestly. Sunday (6th September) kicks off with a 4 ft SSW swell but a solid 16 mph SW wind blowing offshore. The energy is weak (163), so it’s not doing much. The afternoon picks up a touch with a 4 ft SSW swell and a cross-off wind, but the energy is still only moderate (325). It’s just not clean or powerful enough to get excited about.

Then we hit Monday morning (7th September). Now we're talking. The swell bumps up to 5 ft from the south, but the magic is in the wind – glassy, absolutely no wind. This is the standout of the whole period. The energy is moderate (312) and the period is 8 seconds, so it's a short period wind swell, but with those conditions, you’ll be getting some fun, clean waves. This is your best bet for a good session.

The next few days are a bit of a write-off. The swell builds, but the wind and conditions just aren't there. Tuesday (8th September) has an 8 ft SSE swell but it's cross-off and the energy is strong (896). It's not going to be clean. Wednesday (9th) is a mess with a 8 ft S swell and a fresh breeze. Not good.

Thursday morning (10th) sees an 8 ft S swell with 10 second period and moderate energy (1528), but by the afternoon it jumps to a 10 ft S swell with strong energy (1518). That's too big for this break for most of us, only for the experts.

Friday morning (11th) is looking promising again. A 7 ft S swell with a 10 second period, light WNW wind, and it’s clean. The energy is moderate (981). It won't be as good as Monday morning, but still a solid session.

Saturday morning (12th) is another glassy session with a 5 ft S swell and 10 second period. Clean, fun waves. Good for a longboard or a fish.

From Sunday (13th) onwards, it drops off. Swell drops, wind is onshore or cross-onshore, and the conditions are poor. Monday (14th) and Tuesday (15th) are both poor. Wednesday (16th) and Thursday (17th) are not much better. Friday (18th) is a bit better with a cross-off wind, but the swell is small.

The last good looking session is Saturday morning (19th). A tiny 2 ft S swell but with a long 18 second period and a light WNW wind. It's clean, but it's going to be small and the long period will make it break straight. A longboard might be the go.

After that, it's back to ordinary conditions for the rest of the outlook. The energy is weak and the swell is small.

So, to sum it up: the absolute standout is Monday morning (7th September) with the glassy conditions. Saturday morning (12th September) is a close second. If you're an expert, Thursday afternoon (10th) might be worth a look, but it's too big for most. The rest of the period is a bit of a write-off.

Stay stoked.
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.
