North Narrabeen - surf spot statistics

North Narrabeen is a consistent surf spot with a mix of ground and wind swells throughout the year, offering surfable waves in almost every month. The best conditions typically occur from March through August, when ground swell percentages rise above 20%, peaking around May to July at 30-31%. These months also bring better wind conditions, with May, June, and July seeing the highest frequencies of favorable offshore winds (40-41%) and the lowest onshore winds (59-60%). Swell size remains relatively stable year-round, averaging 1.4m to 1.6m, though slightly smaller in late winter (August-September). The summer months (December-February) are less reliable for quality surf due to higher wind swell dominance (82-87%) and poorer wind conditions (bad winds 79-82%). While North Narrabeen rarely has flat spells, autumn and winter provide the best combination of cleaner ground swells and lighter onshore winds, making them the prime time for experienced surfers. That said, the spot remains surfable year-round thanks to consistent swell energy—just expect more wind-affected waves in summer and early autumn.

November at North Narrabeen offers decent surfing conditions with an average swell height of 1.5m and a solid period of 8.4s, providing consistent, well-formed waves. The swell direction is predominantly from the eastern quadrant (ENE to SSE), with the highest frequency of rideable waves (1-2.5m) coming from ENE, E, SE, and SSE. Clean conditions are somewhat limited, with only 24% of winds being ideal—typically light offshore (W, WNW, or NW) or light cross-shore breezes. Stronger onshore winds (especially NE to SE) are more common, which can create choppy or blown-out conditions, particularly when combined with larger swells. The best sessions will likely occur when NE swells meet lighter W/NW winds, offering groomed faces. While bigger days (2m+) are less frequent, they do happen, particularly with E/SE swell directions. Overall, expect a mix of fun, mid-sized waves with occasional clean days and some challenging wind-affected sessions.
