Raglan - surf spot statistics

Raglan, New Zealand, is a world-renowned surf destination known for its consistent ground swells and long left-hand point breaks. The data reveals that the spot enjoys reliable swell year-round, with ground swell dominating (75-87%), complemented by minor wind swell contributions. The best months for surfing in Raglan are typically from March through August, when swell consistency and size peak. March stands out with 87% ground swell, an average size of 1.8m, and relatively better wind conditions (24% favorable). Winter months (May-August) offer the largest waves, averaging 2.2-2.3m, but come with higher chances of unfavorable winds (79-82% bad conditions). Autumn (March-May) strikes a balance between solid swell (1.8-2.2m) and marginally better winds compared to winter. In contrast, summer months (December-February) see slightly smaller swells (1.6-1.8m) but suffer from poor wind conditions (75-85% unfavorable). September-November sees consistent swell size (2.0-2.3m), but wind conditions deteriorate further (85-87% bad). For advanced surfers seeking powerful, clean waves, late autumn to winter (May-August) is ideal despite challenging winds, while intermediates might prefer the shoulder months of March-April when winds are slightly less troublesome and swells remain strong.

In May, Raglan typically offers solid surf conditions with an average swell height of 2.2m and a decent 12.7s period, providing consistent, well-formed waves. The dominant swell direction is from the WSW, making up a significant portion of the swell distribution—particularly in the 1.5-2.5m range—which aligns well with the break for quality rides. However, wind conditions are less reliable, with only 21% of days offering ideal offshore or light winds for surfing. Winds from the SW and WSW are most common but often blow at moderate to strong speeds (10-50kph), potentially creating choppy or cross-shore conditions. While the swell is reliable, surfers should time sessions for days when winds are lighter or more favorable to maximize clean, ridable waves. Overall, May delivers decent surf, but wind variability can impact quality.
