The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for Narrabeen-North over the next couple of weeks.
Truth be told, the start of this run is a bit of a write-off. We’ve got a solid gap with nothing worth paddling out for right through until the end of the month. The wind and swell just aren’t playing ball, with small, messy, and onshore conditions dominating. You’d be fighting a losing battle out there.
Wednesday morning the 19th, we get a brief flicker of hope. The wind drops to glassy, and while the swell is tiny at only 2ft from the ESE with a period of 10 seconds, it’s surfable. The combined wave energy is weak (147), but it’s clean. It’s a last-resort kind of session, but if you’re desperate for a paddle and a few small ones, you could make it work. There’s a similar little window on the 20th and the 25th, but nothing that gets the heart racing.
The first real standout comes on Saturday the 29th of August. The morning shows a jump in size to 5ft from the SSE with a 10-second period. The wind is a clean cross-offshore from the west, and the combined energy is strong at 509. It’s still a bit raw and the score is marginal, but this is the first proper swell of the period and the conditions are much better. The size is manageable for most, but the swell direction is better for the reefs and points than a beach break like this.
Then Sunday the 30th and Monday the 31st see a massive spike in energy, with combined swell readings hitting 1700 and 2948. We’re talking 8ft to 12ft of SE/ESE swell, but it’s accompanied by howling onshore winds from the south, making it a complete mess. This is heavy, powerful, and blown-out. That’s not a paddle-surf day; that’s a day for the kite crew or the very brave. Only experts should even think about it, and even then, the conditions are poor.
Into the first week of September, the energy drops back, but the wind stays messy. Tuesday the 1st of September morning offers a 7ft ESE swell with an 11-second period, but a cross-shore wind spoils it. It’s still a lot of water moving around, with moderate energy (1121), but you’d be scratching for a clean one.
So, for the real standout, I’m pointing you to Saturday the 29th of August. The morning session at Narrabeen-North is your best bet. That 5ft SSE swell with clean cross-offshore wind is the best balance of size and quality in this entire forecast. It’s not perfect, but it’s the only window that looks genuinely worthwhile.

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.
