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.

In July, Kitaizumi offers surfable conditions with an average swell height of 1.3m and a decent period of 9.2s, providing relatively clean and organized waves. The swell predominantly comes from the E to SE directions, with the most consistent wave heights in the 1-1.5m range (occurring around 10-12% of the time from the E and ESE). Larger swells (1.5-2.5m) are less frequent but still present, mainly from the SE and S, offering some punchier days for experienced surfers. Wind conditions are favorable for surfing 33% of the time, with lighter offshore or sideshore winds (especially from the SW to NW) helping to shape the waves. However, stronger onshore winds from the S to SE can occasionally disrupt conditions, particularly in the afternoons. Overall, July delivers rideable waves, with the best sessions likely early in the day when winds are lighter and swells are cleanest. Intermediate to advanced surfers will find the most opportunities, though smaller days may suit beginners.
