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 September, Raglan offers solid surf conditions with an average swell height of 2.3m and a consistent period of 13.0s, ensuring powerful, well-formed waves. The predominant swell direction is from the WSW (20.07% for 1.5-2m and 14.42% for 2-2.5m), delivering quality groundswells that favor the point breaks. Swells from the W and WNW also contribute, particularly in the 2-2.5m+ range, adding variety and occasional larger sets. Wind conditions are less favorable, with only 14% of the time offering ideal offshore or light cross-shore winds. The dominant winds come from the SW and WSW, often in the 20-30kph range (4.21% and 3.59%), which can create choppy conditions. However, mornings or periods with lighter winds (0-10kph) from the ENE or NE (around 0.5-0.6%) provide cleaner surfaces. Overall, September is a reliable month for experienced surfers seeking powerful waves, though wind conditions require patience for optimal sessions.
