Temperatures are expected to climb to around 30 degrees Celsius in inland areas of central and southern South Korea on Tuesday. The rise in temperature is accompanied by increased ozone concentrations, reaching “poor” levels in most regions nationwide. High ultraviolet (UV) radiation is also forecast across the country. Authorities advise citizens to take precautions against heat-related illnesses and sun exposure. The warming trend follows a period of relatively mild weather, raising concerns about potential health impacts. This combination of heat, ozone, and UV radiation poses risks to vulnerable populations, including the elderly and those with respiratory conditions. Citizens are encouraged to stay hydrated and limit outdoor activities during peak hours.
