The Lowdown
Alright, let’s break down what’s coming for Narrabeen-North over the next couple of weeks. It’s a pretty quiet start, so brace yourself for a lot of small, windy days.
The first week is weak. From the 14th through the 21st of September, there’s barely any decent surf. Water temp is 18°, about 0.7° cooler than normal – not a huge deal, just the tail end of winter.
Monday the 14th is a mess: 1.4m of short-period NE swell (5 seconds) with 25 km/h cross-shore winds, combined energy only 131. Choppy and poor. Tuesday the 15th morning is a little cleaner with 1.0m swell and light SW wind, but still small. The rest of that week sees waves under 0.5m, with everything from strong southerlies to glassy conditions on Friday the 18th morning – but the swell is only 0.1m, so you’re not surfing.
Monday the 21st afternoon brings a slight bump to 1.6m from the SSE, but onshore winds from the ESE at 20 km/h keep it messy. Energy hits 153, but still not good.
Now, the first real chance comes Tuesday the 22nd morning: 1.7m of ESE swell with light NE cross-shore winds, energy 220. It’s rated as marginal, so maybe okay for a paddle, but not a standout.
Your best bet across this whole stretch is Thursday morning the 24th of September. Clean 1.7m swell from the ENE, 7-second period, light NNE cross-offshore winds at 10 km/h. Combined energy is 297, and the report says “expect good surf conditions.” That’s the session to aim for. The afternoon gets bigger at 2.2m from the NE, but cross-shore wind makes it less clean, though energy jumps to 542.
Saturday morning the 26th is also clean: 1.5m from the ENE, 8-second period, light NNE offshore breeze, energy 281. Good, but smaller than Thursday.
Sunday the 27th afternoon looks solid with 1.6m from the SSE, clean cross-offshore wind (NNE 15 km/h), energy 416, and “expect good surf conditions.” The morning has 2.1m from the same direction but is marked as marginal.
Monday the 28th has offshore winds all day – NW 15 km/h in the morning, NNW 20 km/h in the afternoon – with waves around 1.5m and 1.4m. Energy is 220 and 392, and both sessions are rated as good. That’s a nice run.
Tuesday the 29th goes back to poor with strong cross-onshore winds and 1.0m waves.
So, the standout is Thursday the 24th morning – clean, 1.7m ENE swell with light offshore wind. Sunday the 27th afternoon and Monday the 28th are also worth getting wet. This spot is an exposed beach and sandbar, and crowds are often, so expect company on the good days. The optimum swell direction is ENE, and that Thursday morning swell hits it perfectly.
Hang in there for that Thursday session – it’s the one.

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.
