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.

February at Kitaizumi offers solid surf conditions with a dominant northeast swell direction, providing consistent wave energy. The average swell height is 1.4m with a healthy 10.4s period, delivering well-formed, rideable waves. The most frequent and sizable swells come from NE (28.81% of waves between 1-2.5m) and ENE (22.66% in the same range), making them the primary swell directions. Smaller but notable contributions from NNE and NW add variety. Wind conditions are less ideal, with only 28% of winds being favorable for surfing—typically lighter offshore winds from the west/northwest quadrant (WNW, NW, NNW) which are most common but can also bring stronger onshore gusts. Larger swells (over 2m) occur about 10% of the time, mainly from NE, ENE, and NW directions. Expect a mix of mid-sized surf with occasional punchy, bigger days, but be mindful of wind quality as it’s often a limiting factor. Pack your standard shortboard and a step-up for bigger NE pulses.
