Various regions across Japan are expected to register above-normal temperatures between June and August, the weather agency says
The southern islands of Okinawa, the northern prefecture of Hokkaido and the six most northerly prefectures on Honshu have a 50 per cent likelihood of elevated temperatures, according to the agency.
Another record-breaking summer could lead to a repeat of Japan’s weather trend over the previous three years, with 2025 the hottest on record. Average temperatures between June and August are expected to be 2.36 degrees Celsius above the 30-year average, surpassing the 1.76 degrees above average reported last year.
Of 153 meteorological stations across the country, 132 recorded record highs, while a temperature of 41.8 degrees was reported in the city of Isesaki, Gunma prefecture, on August 5, the highest ever in Japan. Across 13 prefectures, 30 locations reported above 40 degrees.
Yoshihiro Tachibana, a professor in Mie University’s Department of Environmental Science and Technology, said the mercury level could surge to a new record this year.
