Authorities issued heatstroke alerts for seven locations across Fukuoka and Nagasaki prefectures on Saturday as dangerous heat gripped northern Kyushu [1].
The extreme temperatures pose a significant public health risk, as heat levels frequently exceed normal human body temperature and increase the likelihood of heat-related illnesses.
Forecasts for Saturday indicated that Hita in Oita Prefecture and Kurume in Fukuoka Prefecture would both reach a maximum temperature of 38C [1]. Actual observations already showed high levels of heat, with Yatsushiro in Kumamoto Prefecture recording 36.9C and Dazaifu in Fukuoka Prefecture reaching 36.4C [1].
The dangerous weather pattern is expected to persist through Sunday, July 12. Meteorologists said that both Fukuoka City and Kumamoto City will reach maximum temperatures of 38C [1].
This current heat wave follows a pattern of extreme seasonal spikes in the region. Forecasts for later this month indicate further intensity, specifically on July 23, when Hita is expected to reach 39C [2]. On that same day, Saga City and Kumamoto City are projected to hit 38C [2], while Kurume in Fukuoka Prefecture is also expected to reach 38C [3].
Local governments said residents should take immediate precautions to avoid heatstroke. These measures typically include staying hydrated, using air conditioning, and limiting outdoor activity during the peak heat of the day.

The recurrence of temperatures hitting 38C and 39C across multiple cities in northern Kyushu suggests a severe summer heat cycle. The issuance of heatstroke alerts for seven specific locations indicates that the humidity and temperature combination has reached a critical threshold where the human body can no longer cool itself efficiently, necessitating government-level intervention to prevent mass casualties.
