Seasonal Distribution of Precipitation
Sendai, Japan experiences significant precipitation throughout the year, with seasonal variations influencing the distribution. During the warm and humid summer months (June to August), the city receives heavy rainfall, primarily due to the influence of the summer monsoon.

The spring and autumn seasons (March to May and September to November) tend to bring a moderate amount of rainfall, with occasional dry spells.
Climate and Precipitation Patterns
Sendai’s climate is classified as both humid subtropical and temperate oceanic, contributing to its varied precipitation patterns. The humid subtropical climate, influenced by the warm Pacific Ocean currents, results in abundant rainfall throughout the year.
