On September 22, 2025, when the city was covered by a mobile high pressure system, the morning temperature in Kyoto City dropped to a near-average 19.6°C, marking the first time it had fallen below 20°C in 101 days since June 13. Cosmos flowers bloomed in the northern part of Kyoto, and Japanese pampas grass swayed in the breeze, creating a morning that finally signaled the arrival of autumn.
According to the Japan Meteorological Agency, this year, Kyoto City experienced a record-breaking heatwave, with temperatures above 20°C for 100 consecutive days after dropping to 17.7°C on June 13. As of 9:00 AM on September 22, there had been 61 days of scorching heat with temperatures exceeding 35°C, and a total of 68 days of tropical nights with minimum temperatures above 25°C, both of which were the highest ever recorded.
While the possibility of scorching heat days and tropical nights is almost certain to disappear, temperatures will remain higher than average, and "midsummer days" with temperatures above 30°C are expected to continue for some time to come.
Incidentally, last year in Kyoto City, the lingering heat in September was extremely severe, with the temperature not dropping below 20°C for 105 days from June 21st to October 4th.
