Temperatures from April to June “higher than normal nationwide” Japan Meteorological Agency 3-month forecast. Temperatures will rise due to the effects of the El Niño phenomenon, which is coming to an end.
The Pacific high pressure system south of Japan will become more protruding to the west, making it more likely to be covered with warm, humid air. As a result of this, precipitation is expected to be ``high'' in Okinawa and Amami, ``at or above normal'' on the Pacific side of western Japan, and almost normal in northern and eastern Japan.
