Weather specialists in Japan predict lingering summer heat, known locally as 'zansho,' will continue to affect parts of Kanto and Kyushu during the last weekend of September. According to predictions, the temperatures in these regions will be higher than the seasonal average, creating potential discomfort for the residents. While the peak of summer has passed, people are urged to take measures to guard against heatstroke and other heat-related illnesses.

The concept of 'zansho,' or late-summer heat, is almost peculiar to Japan. It usually refers to the period when summer weather lingers even after the peak of summer is over. Japanese people often take note of these weather changes and adjust their daily activities, even traditions, accordingly. There is a prevalent emphasis on health and precautions against heat-related illnesses during these periods.

While in the US, specifically in areas with a more temperate climate, late-summer heat is less of a concern, the phenomenon is familiar in the southern states. The same is true in Southern Europe, where late summer can bring unexpected heatwaves. However, both these regions often do not exhibit the same level of cultural adaptations as seen in Japan.
