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.

May in Kitaizumi offers generally favorable surf conditions, with an average swell height of 1.5m and a decent period of 8.8s, providing consistent, well-formed waves. The swell direction is predominantly from the east to southeast, with ENE, E, and ESE swells delivering the most rideable waves in the 1-2.5m range. These directions account for the majority of the best conditions, particularly in the 1-1.5m and 1.5-2m categories. The wind is ideal for surfing 31% of the time, with lighter winds (0-20kph) from the east to southeast being the most favorable, while stronger southerly or southwesterly winds (20-40kph) can create choppier conditions. Expect a mix of clean medium-sized waves and occasional bigger sets, especially when swells align with offshore or light cross-shore winds. Overall, Kitaizumi in May is reliable for intermediates to advanced surfers, with peak sessions occurring when ENE-E swells meet lighter easterly winds.
