On August 1, the first day of the month, a heat wave will persist across most of the country, reaching its peak. The sweltering heat is expected to continue through the weekend, lasting until August 2.

According to the Korea Meteorological Administration on July 31, daytime temperatures this weekend will rise between 32 and 38 degrees Celsius. With strong sunlight and urban heat island effects, the perceived temperature in some areas may exceed these figures.

Regionally, Seoul's maximum temperature will reach 34 degrees, while the metropolitan area, including Incheon, Suwon, and Paju, will see highs of 32 to 33 degrees. In Icheon, Gyeonggi Province, temperatures could climb to 36 degrees. In the southern regions, particularly in Gyeongnam, where a heat advisory has been issued, daytime temperatures may approach 39 degrees, with perceived temperatures exceeding 38 degrees.

During the weekend, the central region will experience occasional cloud cover, while the southern regions and Jeju Island will remain mostly clear with strong sunlight.

As the heat wave continues, the risk of heat-related illnesses increases, prompting advisories to limit outdoor activities and prolonged work in the heat, along with ensuring adequate hydration. Tropical nights are also expected nationwide, indicating that nighttime heat will persist.

With no significant rain in the forecast, temperatures in Seoul are expected to rise to 37 degrees next week, indicating that the heat wave may intensify further.
