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.

August in Raglan offers consistent surf with an average swell height of 2.3m and a solid 12.8s period, delivering powerful, well-formed waves. The dominant swell direction is WSW (contributing 20.71% of waves in the 1.5-2m range and 15.44% in the 2-2.5m range), ensuring favorable long-period groundswells that groom the points and reefs. Smaller swells from W and WNW also occur, but WSW swells provide the best quality. Wind conditions are less ideal, with only 18% of days offering clean offshore or light winds; the majority are onshore or cross-shore, particularly from SW to W (notably SW and WSW winds at 10-30kph, which can create chop). While the swell energy is reliable, surfers should watch for wind shifts—early mornings or protected breaks may provide cleaner sessions. Overall, August delivers solid surf but requires patience for optimal conditions.
