Seasonal Patterns of Humidity
Akiruno, Japan, experiences distinct seasonal patterns of humidity. During winter months (December to February), the air is considerably dry, with average relative humidity levels ranging from 40% to 50%. This dryness is influenced by cold, dry air masses originating from Siberia. However, as spring approaches (March), humidity levels begin to climb, reaching their peak during the rainy season in June and July. During this period, the air is saturated with moisture, with relative humidity frequently exceeding 80%. The high humidity is caused by warm, moist air currents from the Pacific Ocean, which provide ample precipitation and contribute to lush vegetation.
Summer and Autumn Humidity
As the rainy season subsides in August, humidity levels gradually decrease. During summer (July to September), the air is generally more humid than in winter but less so than in spring, with relative humidity typically ranging from 60% to 70%. The high temperatures during this time can make the humidity feel oppressive. In autumn (October to November), humidity levels continue to decrease, reaching levels similar to those in winter. The change in humidity is associated with the transition to cooler, drier air masses.
Wind Patterns and Climate
Akiruno, located in the northwestern part of Tokyo, Japan, experiences a humid subtropical climate characterized by hot, humid summers and relatively mild winters.
