The Lowdown
G’day, it’s Rusty here.
Honestly, looking at the next couple of weeks, it’s a bit of a flat spell for Narrabeen-North (Northern Beaches). We’re not going to see anything that’ll have you scrambling for your board bag in a hurry. The first week is pretty much all small, weak, and messy – more of a “cruise on the longboard if you’re desperate” situation than a proper surf. The waves that do show up are mostly in the 3 ft to 5 ft range with short, weak periods. The mornings look cleaner than the afternoons, especially when we get a bit of glassy conditions, but there’s just no push behind them. The combined energy is mostly weak, with readings like 95, 92, and 168 early on, and we dip down to as low as 7 on the 25th. It’s pretty average.
Now, the water temp is 62°F and that’s about 2°F colder than normal for this time of year. Nothing crazy, but you’ll feel it, so bring the booties if you’re sensitive.
The first few days, the 17th and 18th, have a tiny bit of surf in the morning – around 3 ft – with light offshore or glassy winds. Tuesday the 18th morning looks the pick of the early week, with clean 3 ft waves and a period of 7 seconds. It’s surfable, but it’s pretty ordinary. The afternoons are generally shot with onshore breezes chopping things up. Thursday the 20th morning has some clean 3 ft waves with a light cross-offshore wind, which is okay, but it's small.
The weekend of the 22nd and 23rd is looking really slim. Saturday the 22nd is a write-off in the afternoon with a fresh S/SE wind and only 2 ft. Sunday the 23rd is just tiny, dropping to 1 ft.
The second week is looking quieter still. There’s a bit of a bump on the 26th afternoon when a new swell tries to push in, hitting 6 ft with a 10-second period. It’s got some energy (516 in the combined), but it’s coming from the south-southeast and the wind is still onshore, so it’ll be a messy, cross-onshore mess. Not worth getting excited about unless you’re a glutton for punishment. The 27th is similar, with a longer period swell but still poor quality. After that, it drops right off again into the end of the month.
So, there’s nothing here that’s a true standout. No clean, solid days that get the heart racing. It’s a case of picking your moments. The cleanest windows are on the 17th, 18th, and 19th mornings when it’s glassy, and the 21st has a clean offshore wind but it’s small. But with swell that small and periods so short, it’s not going to be epic. Might just be worth taking a few days off and watching the cams.
Stay patient, mate. It’ll turn around eventually.
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.
