South Korean authorities issued a severe heat wave warning for Seoul and Goyang as temperatures are forecast to reach 39 °C [1].

The extreme weather alert highlights a critical public health risk as the metropolitan region faces a peak in prolonged high temperatures. This level of heat can lead to increased heat-related illnesses and puts significant strain on the city's power grid.

Officials have implemented a "heat wave severe warning" across most of the metropolitan area and Gwangyang in South Jeolla Province. A YTN weather reporter said extreme heat approaching 40 °C will prevail under this severe alert [3].

In Seoul, the forecast indicates that midday temperatures will rise to 39 °C [1], which is approximately two degrees higher than the previous day [2]. The intensity of the current weather pattern is the result of a prolonged accumulation of high temperatures across the region [4].

Nighttime relief has also been absent for residents. The temperature in Seoul was recorded at 29.1 °C during the report [2]. This marks the 15th consecutive day that the city has experienced a tropical night [2].

Local residents are advised to limit outdoor activities during the peak heat of the day. The government continues to monitor the situation as the heat wave reaches its highest intensity this week.

Temperatures are forecast to reach 39 °C in the South Korean metropolitan area.

The issuance of a 'severe warning' indicates that the heat wave has surpassed standard seasonal expectations, moving into a category of extreme weather that requires emergency government intervention. The combination of 39 °C daytime highs and a 15-day streak of tropical nights prevents the urban environment from cooling down, which significantly increases the risk of heatstroke for vulnerable populations.
