Hokkaido, Japan’s northernmost prefecture, experiences significant seasonal shifts. October marks a transition from autumn’s vibrant foliage to the onset of winter. Temperatures drop noticeably, and while snow is not yet constant, it becomes increasingly likely, especially in higher elevations and inland areas. Coastal regions tend to remain slightly milder. Daytime highs typically range from 10C to 15C (50F to 59F) while nighttime lows can dip to between 5C and 10C (41F to 50F). This period also sees decreased rainfall compared to September.
Understanding Hokkaido’s autumnal climate is crucial for travelers and residents alike. Proper preparation, including layered clothing and appropriate footwear, is essential for comfortable outdoor activities. The changing conditions impact road travel, particularly in mountainous areas. For those interested in fall foliage viewing, early to mid-October generally provides the most vibrant displays. The transition to cooler temperatures also signals the beginning of the winter sports season, with some ski resorts opening towards the end of the month.
