Monthly Highlights

- Monthly precipitation amounts were significantly above normal in western Japan and the Pacific side of eastern Japan due to active stationary fronts and moist air inflow into the main island of Japan in the middle of this August.
- Monthly sunshine durations were significantly below normal and monthly mean temperatures were below normal in western Japan, and monthly sunshine durations were below normal in eastern Japan due to cloudy and rainy weather conditions associated with the fronts.
- Monthly precipitation amounts were below normal on the Sea of Japan side of northern Japan due to high-pressure systems that often covered the region.
- Since Okinawa/Amami was affected by tropical cyclones and depressions in early August, monthly mean temperatures of the region were below normal.
