The Lowdown
Alright, mate, Rusty here. Let’s have a proper look at what the next couple of weeks are serving up for our stretch of sand. To be honest, it’s a bit of a flat, frustrating start. We’ve got a run of days with hardly anything on offer, but there’s a little light at the end of the tunnel if you’re willing to wait.
The first week is a write-off for any real surf. We’re looking at tiny, weak waves, mostly around 1ft to 2ft, with the swell energy barely registering (17–66). The mornings are glassy early on, but those clean surfaces are just sitting on flat, gutless surf. It’s going to be a lot of sitting on your board, staring at the horizon. The wind is mostly offshore or cross-offshore during this period, but it doesn’t matter when there’s nothing to push around. You’d need a longboard and a whole lot of patience to even catch a ripple.
There’s a brief tease on the morning of the 7th when the swell bumps to 3ft, but the period is a shocker at 5 seconds – that’s just wind chop, not real surf. And it’s still poor. By the 8th afternoon, it builds to over 4ft, but again, the period is short and the conditions are nothing to write home about.
Then the ocean properly wakes up with a south change. From the 9th through the 12th, the wind howls from the south, and while the swell size kicks up – we’re talking 4ft to 5ft – it’s all cross-onshore and blown out. The energy readings climb into the 200-300s, but it’s a messy, junkyard ocean. This isn't for the faint-hearted; it’ll be a battle, not a surf. For a beach break like this, with that much southerly juice and strong wind, it’s looking more like a day for the kite gear than a paddle board.
The real potential shows up on the 13th. The swell jumps to 6ft from the SSE with a period of 9 seconds, and the energy reading hits a strong 488. It’s a solid pulse of swell, but it arrives with more onshore/cross-onshore wind, so it will be lumpy and tough to handle. Still, there's size and power in the water.
The window you want to circle on the calendar is the morning of the 14th. The wind drops right out to glassy, and we’ve still got a very rideable 4ft of swell from the SSE (energy at 318), with that same short 8-second period. It’s not going to be a classic point-break barrel, but after all that flatness and blowouts, it will be a welcome relief – clean faces and no wind to mess it up. Narrabeen-North (Narrabeen) is a very consistent beach/sandbar setup, so even a so-so swell can produce some fun banks. It’s an advanced spot, so it won't be too crowded, but with the lack of options all week, you can bet a few locals will be out.
The 15th morning is the other standout. It’s dead calm with the swell dropping slightly to 3ft from the ENE (energy at 214), with an 8-second period. The conditions will be completely glassy, which is a major positive. It’ll be small, but clean as a whistle. For a high-performance shortboard, you’ll need to hunt for the better sandbanks, as the long-period groundswell effect doesn’t apply here; this is a short-period windswell, so it will be more crumbly than hollow. But for a mid-length or a fish, it could be a fun, playful morning.
Beyond that, the swell looks to fade back down into nothing. It’s a pretty bleak extended forecast overall, but with that first real clean day on the 14th and the glass on the 15th, there’s something to hold out for. As always, forecasts can change, so keep an eye on the charts.
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.
