Gangneung recorded a tropical night on May 31, 2024, marking the third-earliest occurrence of the phenomenon in the city's history [1].
This unusual weather pattern suggests a premature arrival of summer heat, which could impact public health and energy demand across the region. The Korea Meteorological Administration said the event indicates that this year's summer heat will begin early [1].
The tropical night occurred 19 days earlier than the previous year [1]. According to analysis by YTN News, this event ranks as the third-earliest on record, following the second-earliest occurrence in 2014 [1]. The earliest record was set on May 24, 2019 [1].
Beyond the overnight temperatures, the city experienced significant daytime heat. Daytime temperatures reached approximately 33 degrees Celsius [1]. Residents in Gangwon Province are facing these conditions as heat accumulates in the atmosphere ahead of the traditional summer season [1].
"Nighttime in Gangneung saw the first tropical night of the year, which is 19 days faster than last year and the third-fastest record ever," a YTN News anchor said [1].
Reporter Jung Hye-yoon of YTN News said the current analysis places this event in third place, trailing the 2014 record [1]. The combination of high daytime temperatures and warm nights is a result of heat building up in the atmosphere as the season transitions [1].
“this event ranks as the third-earliest on record”
The emergence of tropical nights in May, typically a mild spring month in South Korea, signals a shift in seasonal timing. When heat accumulates in the atmosphere this early, it often precedes a more intense summer period, potentially straining power grids and increasing the risk of heat-related illnesses before official heatwave protocols are fully implemented.
