Kitaizumi - surf spot statistics

Kitaizumi in Japan offers varying surf conditions throughout the year, with distinct seasonal patterns influencing swell and wind quality. The best months for surfers generally align with higher ground swell percentages, manageable wind conditions, and consistent wave size. From January to March, ground swells dominate (59% in January, 55% in February, 46% in March) with mean swell sizes around 1.4-1.6m, offering reliable wave energy. However, wind conditions are less favorable, with bad winds prevailing 72% of the time, which can create choppy surfaces. The mid-year months (April to August) see a shift toward wind swells (peaking at 88% in June) and smaller average wave sizes (1.3-1.6m), making conditions less ideal for advanced surfers seeking clean, powerful waves. While summer months like July and August bring slightly better wind stats (33% good winds), the prevalence of wind swells often results in weaker, less organized waves. Autumn (September to November) marks a transitional period, with ground swells increasing again (28-40%) and mean swell sizes holding steady at 1.4-1.6m. November stands out with 35% good wind conditions—the highest of the year—offering a better balance between swell quality and offshore winds. December sees a return to mixed ground and wind swells (51%/45%) but retains smaller waves (1.3m) and challenging winds (69% bad). Overall, the prime window for surfing at Kitaizumi is late autumn (November), when ground swells remain decent, wind conditions improve slightly, and wave size is consistent. Winter (January-March) provides powerful ground swells but suffers from poor winds, while summer months are dominated by weaker wind swells. Experienced surfers may prioritize winter for its raw swell energy, but November offers the most balanced conditions.

November at Kitaizumi offers decent surf conditions with a mix of swell sizes and generally favorable wind patterns. The average swell height is 1.4m with a solid period of 9.8s, providing consistent energy for intermediate to advanced surfers. The dominant swell directions are from the east-northeast (ENE) and east (E), with the majority of waves falling in the 0.5-2m range—ideal for performance surfing. Larger swells (2m+) are less frequent but occasionally produce powerful sets, particularly from ENE and ESE directions. Wind conditions are favorable 35% of the time, with offshore or light winds most common from the east and northeast. Stronger onshore winds occasionally come from the west and northwest, particularly in the 10-30kph range, which can degrade wave quality. Overall, November is a reliable month for surfers seeking playful to powerful waves, though timing sessions around wind shifts is key for optimal conditions.
