Fitzroy Beach - surf spot statistics

Fitzroy Beach in New Zealand is a consistent surf spot with reliable ground swells throughout the year, though the best conditions vary seasonally. The swell is predominantly ground swell, peaking in frequency from February to April (82-83%), while wind swell is generally low, except in December (31%). The mean swell size increases from 1.5–1.6m in summer (January-March) to a peak of 2.1–2.2m from May to October, offering more powerful waves in autumn and winter. However, wind conditions are challenging, with good winds only occurring 14-25% of the time, worst in spring (September-November: 14-16%). The best balance between swell size and wind is likely in April, when ground swell is still strong (82%), average size increases to 1.8m, and good winds reach 25%. Winter months (May-August) bring bigger waves (2.1-2.2m) but persistent onshore winds (77-80% bad conditions). Summer (January-March) has smaller swells but slightly better wind chances (19-24%), making it more suitable for intermediate surfers. Overall, advanced surfers may prefer autumn (April-May) for larger swells and marginally better winds, while summer offers more manageable conditions for less experienced riders. If you prioritize size, winter is powerful but less consistent with clean conditions.

September at Fitzroy Beach delivers consistent surf with an average swell height of 2.2m and a solid 13.0s period, indicating powerful, well-spaced waves. The dominant swell direction is from the WSW, which produces the highest frequency of rideable waves—particularly in the 1.5–2.5m range (over 32% combined for WSW). This direction also brings the largest waves (over 2.5m, 1.15%). SW and WNW swells contribute smaller but still surfable waves, while northerly and easterly swells are negligible. Wind conditions are less favorable, with only 15% of days offering ideal offshore or light winds. The prevailing winds come from the W to NW sectors, often blowing 20–30kph (5.42% WSW), which can create choppy conditions. However, occasional lighter winds (0–20kph) from the N, NE, or SE directions (around 2–4% each) provide cleaner surfaces. Overall, September is reliable for intermediate to advanced surfers, with the best sessions occurring when WSW swells coincide with rare lighter winds. Bigger, more powerful days are likely, but wind management is key.
