Humidity in Hakodate, Japan Overview

Hakodate, a captivating port city nestled in Hokkaido, Japan, experiences varying levels of humidity throughout the year. While the summers tend to be warm and humid, with average relative humidity levels hovering around 70-80%, the winters are relatively dry, with humidity levels dropping to around 50-60%. The humidity in Hakodate is primarily influenced by its maritime climate, which is characterized by the presence of large bodies of water that regulate temperature and moisture levels.

During the summer months, warm and moist air from the Pacific Ocean is carried inland by prevailing winds, resulting in higher humidity levels. This humidity can contribute to a muggy and uncomfortable feeling, especially during the peak of summer when temperatures can soar to the mid-30s Celsius (90s Fahrenheit). In contrast, during the winter months, cold and dry air from the Siberian mainland dominates the weather patterns, leading to lower humidity levels. These conditions create a crisp and refreshing atmosphere, with occasional snowfall adding to the city’s winter charm.

Wind Patterns and Seasonal Variations

Hakodate, located on the southern tip of Hokkaido, Japan, experiences a unique wind regime influenced by its geographical location. The prevailing wind direction is westerly, due to the strong atmospheric circulation in East Asia. During the summer months, the sea breeze from the cooler Hakodate Bay provides a refreshing contrast to the warmer land masses. In winter, on the other hand, strong northwesterlies known as the “Yamase” winds descend from the surrounding mountains, bringing cold and humid conditions. These wind patterns contribute to the city’s distinctive climate, with average annual wind speeds exceeding 6 meters per second.
