Breaking: First Heatwave Advisory Issued for 6 Gyeonggi Areas with Feels-Like Temperature of 33°C

Introduction to the First Heatwave Advisory of 2025

On June 15, 2025, starting at 9 a.m., the Korea Meteorological Administration (KMA) issued the first heatwave advisory of the year for six areas in Gyeonggi Province: Pocheon, Gapyeong, Paju, Anseong, Yeoju, and Yangpyeong. This advisory warns residents to prepare for high temperatures and humidity, with feels-like temperatures expected to reach around 33°C.

Understanding the Heatwave Advisory Criteria

The heatwave advisory is issued when the daily maximum feels-like temperature is expected to be 33°C or higher for two consecutive days. The feels-like temperature accounts for both air temperature and humidity, making the perceived heat more intense. For instance, when humidity increases by 10%, the feels-like temperature rises by about 1°C. This year’s first advisory came five days later than last year, when the first heatwave warning was issued on June 10.

Weather Conditions Leading to the Advisory

The KMA explained that strong sunlight combined with high humidity in these inland areas is driving the rise in feels-like temperatures. The high humidity is partly due to recent rains, which increase moisture in the air, exacerbating the heat sensation. Despite the advisory, localized rain showers are expected from the night of June 15, which may shorten the duration of the heatwave conditions.

Community and Public Reactions

Local communities have responded with caution, sharing tips on social media and community forums such as Naver and Daum about staying hydrated and avoiding outdoor activities during peak heat hours. Some residents expressed concern about the impact of early summer heat on vulnerable populations like the elderly and children. Online communities also discussed the delayed onset of the heatwave compared to previous years, noting the variability of climate patterns.

Cultural Context and Importance of Heatwave Advisories in Korea

In Korea, heatwaves are a significant public health concern, especially given the high humidity that intensifies discomfort and health risks. The government and local authorities use these advisories to encourage preventive measures such as wearing light clothing, drinking plenty of water, and taking breaks in shaded or air-conditioned areas. The heatwave advisory system is well-known among Koreans, who often share advice and warnings through popular online platforms and messaging apps.

Looking Ahead: Weather Forecast and Safety Tips

The KMA forecasts that after the brief rain expected on the night of June 15, temperatures will continue to be high across inland regions, with many areas experiencing daytime temperatures around 30°C or higher. Residents are advised to monitor weather updates and follow safety guidelines to reduce heat-related illnesses. Public health officials emphasize the importance of community support, especially for those living alone or with limited access to cooling facilities.
