The Lowdown
Hey, Rusty here. Let’s talk about Narrabeen-North, a beach/sandbar spot that catches the swell. Water temp is about normal for this time of year.
First up, Tuesday August 11th: not huge, but there’s something. Morning has 2ft of swell from the ENE, period 9 seconds. Wind is W at 15 km/h, a cross-off, so it’s clean. Swell energy is weak at 78. It’s surfable, just ordinary. Tuesday afternoon: still 2ft from the ENE, period 9 secs, wind turns light offshore from the WNW at 10 km/h – glassy. Energy up to 96, still weak. You could get a little fun one if you’re nearby.
Then it goes quiet. From Wednesday August 12th right through to Saturday August 22nd, it’s mostly poor. There’s a bump of 4ft on Sunday August 16th, but period is a short 6 seconds from the SSE and energy hits 167 (moderate), with onshore wind and mess. By Monday August 17th, swell hits 7ft from the SE, period 8 secs, energy 549, but onshore wind and rain make it poor. That size with short period and onshore wind at a beach break is kite-surfing territory, not paddle. This onshore, messy pattern sticks around until August 20th.
After that dry spell, Friday August 21st morning is a small bright spot. Swell drops to 3ft from the ENE, period 8 secs. Wind is light at 5 km/h from the ESE, glassy calm. Energy is moderate at 129. Conditions are clean, but the waves are ordinary. A quiet, glassy session if you’re keen.
Saturday August 22nd morning and afternoon offer 4ft from the ENE, period 8-9 secs, with a gentle cross-shore breeze from the NE at 15 km/h. Energy moderate at 264, but it’s marginal with lumpy cross-chop. Not a standout.
Now, the big one: Wednesday August 26th morning. This is the best on offer. Swell is 8ft from the SE, period 8 seconds – solid size, short period means it’ll be heavy. Wind is from the NNW at 15 km/h, a cross-off, clean. Combined swell energy is very strong at 1330. This is expert-only: over 8ft and short period, it’s going to be challenging. Crowds are likely. For the experienced crew, conditions are excellent.
So there you have it – a slow start, a long flat run, and then a more distant, promising window on the 26th. That late date is still a couple weeks out, so it’s promising but not locked in yet.
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.
