Long-Term Trends

Over the past several decades, Iizuka has experienced a gradual increase in annual precipitation.

The increase in precipitation has implications for water management and infrastructure, as well as the potential for flooding and other natural disasters.

In addition to the long-term trend, Iizuka also exhibits inter-annual variability in precipitation. Some years may receive significantly more or less rainfall than average, depending on factors such as El Niño-Southern Oscillation (ENSO) events and other climate patterns. These variations can impact local water resources and agricultural production.

Seasonal Variations in Rainfall

Iizuka, Japan experiences distinct seasonal variations in rainfall. During the summer months (June to September), the city receives heavy precipitation due to the influence of the East Asian monsoon.

The summer rainfall is often accompanied by intense thunderstorms and sporadic periods of heavy downpours.

In contrast, the winter months (December to February) are relatively dry, with monthly rainfall amounts typically below 50 millimeters. The lack of precipitation during this time is primarily attributed to the dominance of cold and dry air masses from Siberia. The precipitation that does occur during the winter tends to be in the form of light snow or sleet.
