The Lowdown
Alright, let’s talk about Narrabeen-North in the units you’re used to. This is a long stretch of small, average surf, and I’m not going to sugarcoat it.
For the first week, the only real chance of a decent session is Tuesday afternoon, August 25. You’re looking at a 5ft NE swell, with a period of about 8 seconds, and a nice cross-off breeze from the NNW at 9 mph. The combined energy of all swells is moderate (229). That’s the pick of the bunch. The water is around 63°F, which is pretty normal for this time of year.
Tuesday afternoon (August 25) is the standout. That offshore wind will keep the surface clean, and the waves will be in the waist-to-chest high range. It’s a beach break, very consistent, so you’ll get plenty of waves, but it’s often crowded, so expect company.
After that, it’s a long slide into small surf. Wednesday (August 26) gets messy with a southerly wind and rain. Then from Thursday (August 27) all the way into early September, you’re looking at waves under 2ft. The energy is weak (two-digit numbers), and the wind is mostly onshore or side. A few mornings are glassy, like Friday (August 28) with 2ft from the ENE, but it’s just too small to be worth it.
The second week is even quieter. From September 1 onward, the swell barely reaches 2ft, with energy under 100. The winds are often offshore in the mornings, teasing you with clean conditions but no real wave. There’s a small bump on Tuesday, September 8, with a 4ft NE swell and moderate energy (140), but the period is short at 7 seconds. It’s surfable, but not special.
So, if you’re itching to get wet, Tuesday afternoon, August 25, is your only real play. After that, the bank is flat for days. It’s a normal quiet spell for this area, so don’t hold your breath. The forecast can change, but as it stands, that’s the story.

A general guide to surfing at Narrabeen-North can be found by selecting the local surf guide option on the grey menu. Our Narrabeen-North 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.

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-North 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.
