Why is Humidity So High in Japan?

Japan experiences high humidity in the summer due to its geographical location and climatic conditions. Situated in the East Asian monsoon region, Japan is affected by the seasonal winds that bring moist air from the Pacific Ocean.

During the summer months, the southerly winds from the Pacific carry warm and humid air over the archipelago. Additionally, Japan’s mountainous terrain contributes to this effect by trapping moisture-laden air masses.

The combination of these factors results in persistently high humidity levels, making the summer feel much hotter and stickier.

Overview of Typical Summer Weather Patterns

The summer season in Japan typically runs from June to September. During this period, temperatures can range from 25°C (77°F) to 35°C (95°F) or higher. The season begins with the 梅雨 (tsuyu) or rainy season, lasting from early June to mid-July, characterized by frequent and heavy rain showers.

After the rainy season, the weather becomes hotter and more humid, with August being the peak of summer heat. Heatwaves are common, and typhoons may also occur, bringing heavy rain and strong winds.

These weather patterns create a challenging environment for both locals and visitors, necessitating effective strategies to cope with the heat and humidity.
