Annual Averages

When considering the annual average temperature, Edogawa enjoys a pleasant climate with a mean temperature of 15.8°C (60.4°F). This mild climate is influenced by the region’s proximity to the Pacific Ocean, which helps regulate temperatures, preventing extreme heat or cold. The annual temperature range, the difference between the warmest and coldest months, is relatively narrow, contributing to Edogawa’s consistent and comfortable climate.

Formation and Appearance

Clouds in Edogawa, Japan, are shaped by the interaction of various atmospheric factors. The presence of warm ocean currents and the surrounding mountains contributes to the abundant moisture in the air. As moisture condenses and rises, it forms clouds of different shapes and sizes. During the morning hours, clouds often form as low-lying stratus or stratocumulus clouds, which appear as flat gray layers or puffy masses. As the day progresses and the sun heats the air, convection currents develop, leading to the formation of cumulus clouds. These clouds have a characteristic rounded top and flat base, resembling cotton balls. In the afternoon, these cumulus clouds can further develop into towering cumulonimbus clouds, which bring thunderstorms and heavy rainfall.

Impact on Weather

The presence of clouds has a significant impact on the weather conditions in Edogawa. Clouds can provide shade from the sun, reducing temperatures and making it more comfortable during hot summer months. They also trap heat from the earth’s surface at night, preventing temperatures from dropping too low. Clouds act as a barrier to incoming solar radiation, affecting the amount of sunlight reaching the ground and influencing the growth of vegetation. Additionally, clouds are instrumental in the formation of precipitation. As water vapor condenses within clouds, it forms water droplets or ice crystals, which can then fall as rain, snow, or hail. The type and intensity of precipitation are influenced by the cloud’s thickness, temperature, and moisture content.

Annual Precipitation

Edogawa, located in the Greater Tokyo Area, experiences a humid subtropical climate, characterized by abundant rainfall throughout the year. The annual precipitation in Edogawa averages around 1,500 millimeters (59 inches), with marked seasonal variations. The wettest months are May to September, when the rainy season (tsuyu) and typhoon season typically bring heavy rainfall. During these months, Edogawa can receive more than 200 millimeters (8 inches) of precipitation per month.

Seasonal Distribution

The driest months in Edogawa are December and January, when precipitation averages below 50 millimeters (2 inches) per month. This period is known as the dry season, and it offers a respite from the high humidity and rainfall of the rest of the year. The annual precipitation in Edogawa is relatively evenly distributed throughout the remaining months, with October, November, and February receiving moderate amounts of rainfall. The city’s proximity to the Pacific Ocean and the warm Kuroshio Current contribute to its high humidity and abundant precipitation.

Annual Precipitation Patterns

Edogawa, Japan, experiences a temperate climate with abundant precipitation throughout the year. The annual rainfall averages around 1,500-1,700 millimeters (59-67 inches), distributed relatively evenly across the seasons. However, there are slight seasonal variations, with the wettest months being June, July, and September. During these months, heavy rainfall is common due to the influence of the summer monsoon and tropical cyclones. In contrast, winter months (December to February) tend to be drier, although occasional snowfall and sleet can occur.

Intensity and Variability

The intensity and variability of rainfall in Edogawa can vary significantly from year to year. The city is susceptible to extreme rainfall events, such as cloudbursts and torrential downpours, which can lead to flash floods and landslides. These events are more likely to occur during the summer months, when atmospheric instability and high levels of atmospheric moisture create favorable conditions for heavy thunderstorms. In contrast, droughts, while less common, can also occur during the dry season, typically during the late winter and early spring. These events are often associated with high-pressure systems that block precipitation-bearing clouds.
