Seoul Swelters: Record 37.7°C Shatters 117-Year-Old High

Seoul Experiences Hottest Early July On Record, Breaking 117-Year Streak

Seoul, South Korea, Is currently grappling with an unprecedented heatwave. the capital city recorded a scorching 37.7 degrees Celsius (99.86 degrees Fahrenheit) on Tuesday afternoon, marking the highest temperature ever registered for early July as observations began in 1908.

This new record surpasses the previous high of 36.8 C set on July 9, 1939, effectively breaking an 86-year-old benchmark. it represents Seoul’s hottest early July day in 117 years.

Nationwide Heatwave

The extreme heat isn’t limited to Seoul. Numerous cities across South Korea have also reported record-breaking temperatures for this time of year. These include Incheon (35.6 C), Wonju (35.4 C), Suwon (35.7 C), Cheongju (35.7 C), Daejeon (36.3 C), Gochang (35.8 C), and Busan (34.5 C).

Remarkably, temperatures in Paju and Gwangmyeong, cities bordering Seoul, exceeded 40 degrees Celsius (104 degrees fahrenheit). this marks the first time temperatures have surpassed this threshold in july.

Looking Ahead

While a slight respite is anticipated around Friday, the heat is expected to return with the influx of hot, humid air from the south. Forecasters predict the heatwave will persist until rainfall arrives in the capital area and western Gangwon Province around July 16.

seoul has already endured nine consecutive tropical nights, defined as temperatures remaining above 25 degrees Celsius (77 degrees Fahrenheit) overnight. the nation’s average temperature, excluding Jeju Island, for the first seven days of july was 28.1 C, the highest since record-keeping began in 1973.

Unprecedented Heatwave Grips South Korea’s Capital

Seoul is experiencing an unprecedented heatwave, with temperatures soaring to a record-breaking 37.7°C (99.86°F) on July 8th, 2025. This surpasses the previous high of 37.2°C recorded in 1908 – a staggering 117-year-old record.The extreme heat is impacting daily life across the city, prompting health advisories and straining infrastructure. This intense heat in Seoul is part of a broader pattern of rising global temperatures and increasingly frequent extreme weather events.

Impact on Daily Life in Seoul

The record heat is causing significant disruption for residents and visitors alike. Here’s a breakdown of the key impacts:

Public Health Concerns: Heatstroke and heat exhaustion cases are surging. Hospitals are reporting a significant increase in patients presenting with heat-related illnesses. Vulnerable populations – the elderly, young children, and those with pre-existing health conditions – are notably at risk.

Transportation Disruptions: Extreme heat can cause railway tracks to buckle and roads to soften, leading to potential delays and disruptions in public transportation. Seoul’s subway system, while extensive, can become stiflingly hot during peak hours.

Power Grid Strain: Increased demand for air conditioning is putting a strain on the power grid, raising concerns about potential blackouts. south Korea’s energy ministry is closely monitoring the situation and urging citizens to conserve energy.

Agricultural Impact: The heatwave is impacting agricultural yields in surrounding areas, perhaps leading to higher food prices. Rice paddies and other crops are suffering from water stress.

Tourism affected: Sightseeing in Seoul, even at popular destinations like Gyeongbokgung Palace and the Bukchon Hanok Village (as highlighted in recent Seoul travel guides), is becoming challenging during peak hours. Tourists are advised to take precautions.

Understanding the Current Heatwave: contributing Factors

Several factors are contributing to this remarkable heatwave:

Climate Change: The overarching driver is global climate change, leading to a long-term trend of rising temperatures.

High-Pressure System: A persistent high-pressure system is dominating the Korean Peninsula, blocking cooler air masses from entering the region.

Urban Heat Island Effect: Seoul, a densely populated metropolis, experiences the urban heat island effect, were concrete and asphalt absorb and retain heat, making the city substantially warmer than surrounding rural areas.

Lack of Rainfall: Below-average rainfall in recent weeks has exacerbated the heat, leading to drier conditions and increased temperatures.

Health and Safety Recommendations During Extreme Heat

Protecting yourself from the heat is crucial.Here are some essential recommendations:

1. Stay Hydrated: Drink plenty of water throughout the day, even if you don’t feel thirsty.Avoid sugary drinks and alcohol, which can dehydrate you.
2. Seek Shade: Limit outdoor activities during peak heat hours (typically between 12 PM and 5 PM). Seek shade whenever possible.
3. Wear Appropriate Clothing: Wear light-colored, loose-fitting clothing made of breathable fabrics.
4. Use Cooling Methods: take cool showers or baths, use fans, and apply cool compresses to your neck and wrists.
5. Check on Vulnerable Individuals: Regularly check on elderly relatives, neighbors, and friends to ensure they are staying cool and hydrated.
6. Recognize Heatstroke Symptoms: Be aware of the symptoms of heatstroke, including high body temperature, confusion, headache, and loss of consciousness. Seek immediate medical attention if you suspect someone is experiencing heatstroke.

Long-Term Solutions and Adaptation Strategies

Addressing the increasing frequency and intensity of heatwaves requires a multi-faceted approach:

Reducing Greenhouse Gas Emissions: Global efforts to reduce greenhouse gas emissions are essential to mitigate climate change and limit future warming.

Urban Greening Initiatives: Increasing green spaces in cities can definitely help reduce the urban heat island effect. Planting trees and creating parks can provide shade and cool the air.

Cool Roofs and Pavements: Implementing cool roof and pavement technologies can reflect sunlight and reduce heat absorption.

Early Warning Systems: Developing and improving early warning systems for heatwaves can help communities prepare and protect vulnerable populations.

Infrastructure Improvements: Investing in infrastructure upgrades, such as a more resilient power grid and improved public transportation, can definitely help mitigate the impacts of extreme heat.

Real-World Example: Seoul’s Heatwave Response Plan

The Seoul Metropolitan Government has activated its heatwave response plan, which includes:

Operation of Cooling Centers: Opening public cooling centers in community centers and libraries.

Distribution of Cooling Supplies: Providing cooling vests and fans to vulnerable populations.

Public Awareness Campaigns: Launching public awareness campaigns to educate citizens about heat safety.

monitoring of Heat-Related Illnesses: Closely monitoring hospital admissions for heat-related illnesses.
