This summer has been a record-breaking heat wave, and the high temperature trend will continue in autumn. It seems that the severe lingering summer heat will last for a long time. Precipitation in September will be above normal in eastern and western Japan. Here are the weather and temperature trends for the next three months (September to November).
High temperature trend in autumn Slow progress of season
This year has been a record heat wave, but the high temperature trend is expected to continue in autumn.
From September to November, the whole country will be covered with warm air. Average temperatures are expected to be higher than average nationwide in September and October. In November, northern Japan will be near normal, but eastern and western Japan will be near normal or above normal, and Okinawa and Amami will be above normal.
Severe lingering heat will continue in September, and the progress of the season is likely to slow down from October onwards. Short sleeves will still be on the market for a while. The autumn leaves may also change color later than usual. Even in November, cold air from the north tends to be weak in eastern and western Japan, and winter news such as the first snowfall may be delayed.
September tends to have more precipitation in eastern and western Japan
Over the past month, some areas in western Japan experienced record-breaking rainfall due to Typhoon No. 6 and No. 7, while other areas experienced extremely low rainfall. From Hokuriku to the Sea of Japan side of Tohoku and Kanto-Koshin, the amount of rainfall is less than normal, and there are places where the water storage rate of dams is decreasing.
The amount of rainfall in September will be normal in northern Japan and eastern Japan along the Sea of Japan. The weather changes every few days, and rain is likely to be a blessing. The Pacific side of eastern Japan, western Japan, and Okinawa/Amami will be affected by warm, moist air around the edge of the Pacific anticyclone and an autumnal rain front, so precipitation will be above normal. The water jars in the Kanto area may recover somewhat, but the water shortage will not be resolved immediately, so please continue to conserve water.
Precipitation in October and November will be at the same level nationwide.
Northern Japan: Hokkaido/Tohoku
Eastern Japan: Kanto Koshin, Tokai, Hokuriku
Western Japan: Kinki, Chugoku, Shikoku, Kyushu
