Seoul Issues First Heat Wave Warning of 2025 as Temperatures Expected to Reach 36°C

Seoul meteorological authorities issued the city's first heat wave warning of 2025 on July 7, with temperatures expected to soar to 36°C (97°F) on Tuesday. The extreme weather has prompted emergency health measures as heat-related illnesses surge across the metropolitan area, marking the beginning of what experts predict could be an exceptionally challenging summer season.

Meteorological Conditions and Forecast

According to the Korea Meteorological Administration, the heat wave warning will take effect from July 8, with maximum temperatures in Seoul expected to reach 36°C. This marks the first such warning issued for the capital this year, arriving somewhat later than in previous years but with potentially greater intensity.

The persistent high-pressure system from the North Pacific continues to dominate the Korean Peninsula, creating stable atmospheric conditions that trap heat and prevent cooling. Urban heat island effects in downtown Seoul are expected to make the perceived temperature even higher than recorded measurements, potentially pushing the felt temperature above 40°C in some areas.

Minimum overnight temperatures are forecast to remain around 25°C, creating tropical night conditions that prevent adequate cooling and recovery. This combination of extreme daytime heat and persistently warm nights poses significant health risks, particularly for vulnerable populations.

Rising Heat-Related Health Emergencies

The escalating temperatures have led to a dramatic increase in heat-related medical emergencies across Seoul. On July 7 alone, nearly 60 people sought emergency treatment at major hospitals throughout the city for suspected heat-related illnesses. Tragically, two individuals succumbed to heat-related complications, highlighting the serious nature of the current situation.

Most heat illness victims are elderly residents and outdoor workers, particularly those in construction and delivery services. Medical professionals report seeing numerous cases of dehydration, heat exhaustion, and heat stroke, with symptoms ranging from dizziness and nausea to loss of consciousness.

Emergency room physicians emphasize the critical importance of immediate cooling measures for heat stroke victims. "The key is rapid recognition and immediate action to lower body temperature," explained Dr. Kim Min-jung from Seoul National University Hospital. "Every minute counts in preventing permanent organ damage."

Government and Municipal Response

Seoul Metropolitan Government has expanded its network of cooling centers to help residents escape the dangerous heat. Currently, more than 1,400 designated cooling shelters operate throughout the city, including community centers, libraries, subway stations, and shopping malls equipped with air conditioning.

The city has also intensified welfare checks for vulnerable populations, including elderly residents living alone and those in low-income housing. Social workers and visiting nurses conduct regular safety visits, providing cooling supplies and bottled water when necessary.

Fire and emergency services have increased ambulance availability and updated heat emergency response protocols. The 119 emergency hotline now provides enhanced telephone consultation for suspected heat-related symptoms, helping callers determine when immediate medical attention is required.

Public Health Guidance and Safety Measures

Health authorities have issued comprehensive guidance for heat wave safety. Key recommendations include avoiding outdoor activities between noon and 5 PM, wearing light-colored, loose-fitting clothing, and maintaining frequent hydration even before feeling thirsty. Officials particularly warn against alcohol and caffeine consumption, which can worsen dehydration.

Indoor cooling strategies focus on appropriate air conditioning use while maintaining energy conservation. The government recommends maintaining indoor temperatures between 26-28°C to balance comfort with power grid stability.

Long-term Outlook and Preparedness

Meteorologists warn that the current heat wave represents just the beginning of what could be an extended period of extreme temperatures. Climate data suggests that this summer may set new records for sustained high temperatures, with few atmospheric patterns likely to provide relief in the coming weeks.

The situation requires both individual vigilance and collective social responsibility. Public health experts emphasize that heat waves are among the deadliest weather phenomena, often causing more casualties than other natural disasters due to their silent, gradual impact on human health.

As Seoul braces for potentially record-breaking temperatures, the city's response will test both its emergency preparedness systems and community resilience in the face of increasingly extreme weather events linked to climate change.
