The Lowdown
G’day, Rusty here. Let’s have a look at what’s on offer for Narrabeen-North over the next couple of weeks.
Right now, the story is pretty quiet. We’ve got a long stretch of small, ordinary surf kicking off from Wednesday morning and dragging through most of the following week. The first decent chance doesn’t roll in until Thursday the 27th of August, so there’s a solid gap of about a week with nothing worth paddling out for. The water temperature is sitting about average for this time of year, so no surprises there.
When things finally pick up, Thursday the 27th of August morning is the standout. Narrabeen-North sees a clean 3 ft swell from the ESE with a period of 8 seconds, and a moderate combined wave energy of 209. The wind is offshore from the NNW at 9 mph, giving you glassy, clean conditions. This is a beach/sandbar setup, so it’s an exposed one, and the optimum swell direction is ENE, so that ESE swell is a nice fit. Crowds are possible here, so keep that in mind. The afternoon only gets better – the swell jumps to 5 ft from the SE with a period of 8 seconds, combined energy of 313, and light N winds at 6 mph, making for clean, fun waves. This is the pick of the whole forecast.
Beyond that, the following days mix in some ordinary conditions with light rain and onshore winds, and the swell stays small and messy. Saturday the 29th of August brings a big spike in swell – 12 ft from the SSE – but with strong onshore winds at 28 mph, it’s blown out and only for experts. The energy hits 1994, but it’s not worth it for paddle surfing. That setup looks more interesting for kite surfing than a traditional surf.
The last few days of the forecast into early September fade back to small, weak swells with cross-shore or onshore winds, so nothing to get excited about.
Rusty.

Information about the Narrabeen-North Surf forecast
The above surf forecast table for Narrabeen-North provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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. If you surf the same spot (Narrabeen-North) 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-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.
