Warm Weekend Weather for Korea: Rain & Strong Winds Ahead

A welcome respite from winter’s chill is arriving across South Korea this weekend, with temperatures expected to climb significantly, potentially reaching 20 degrees Celsius in some areas. While the warmer weather offers a tempting invitation for outdoor activities, forecasters are also warning of strong winds and localized rainfall, particularly in central regions. This combination of pleasant temperatures and potentially hazardous conditions requires careful planning for anyone considering a weekend outing.

The approaching warmth is attributed to a southward flow of warm, southwest winds influenced by a high-pressure system positioned off the southern coast of Japan. This, coupled with increased solar radiation, is expected to bring temperatures well above seasonal averages for this time of year. The shift in weather patterns presents a stark contrast to recent colder spells and offers a glimpse of spring’s arrival, though it’s a fleeting one, as cooler temperatures are predicted to return next week.

Weekend Weather Forecast: A Detailed Look

According to the latest forecasts from the Korea Meteorological Administration, Saturday, February 21st, and Sunday, February 22nd, will see generally mild conditions across the country, including the mountainous Gangwon province. However, the central region should prepare for rainfall between dawn and morning on Sunday, with precipitation expected to be light, less than 5 millimeters. The combination of warmer temperatures and potential rainfall creates a humid environment, which may feel pleasant but also requires attention to potential slippery conditions.

Specific temperature predictions for major cities include a low of 4°C and a high of 17°C in Seoul, 6°C and 12°C in Incheon, 3°C and 19°C in Daejeon, 3°C and 18°C in Gwangju, 1°C and 19°C in Daegu, 2°C and 18°C in Ulsan, and 7°C and 16°C in Busan. Notably, areas in North Gyeongsang Province, such as Sangju and Yecheon, are forecast to reach a high of 20°C, offering particularly pleasant conditions for outdoor activities. These warmer temperatures are a significant departure from the typical February climate in South Korea.

Strong Winds and Safety Concerns

Alongside the warmer temperatures, a significant weather concern is the anticipated strong winds. From the afternoon of February 21st through February 23rd, winds with instantaneous speeds of around 55 kilometers per hour (70 kilometers per hour in mountainous regions) are expected to sweep across most of the country. Coastal areas, the mountains of Gangwon province, and the eastern mountains of Gyeongbuk province are particularly vulnerable, with potential wind gusts reaching up to 70 kilometers per hour (90 kilometers per hour in mountainous areas). These strong winds pose a risk to infrastructure and could lead to safety hazards, requiring caution during outdoor activities.

The Korea Meteorological Administration advises securing outdoor objects, exercising caution during mountain hikes, and being aware of potential disruptions to transportation. The strong winds will also impact marine conditions, with rough seas expected along the West Sea starting in the afternoon of February 21st, extending to the East Sea, southwestern coast, and south of Jeju Island by nightfall. Waves are predicted to reach heights of 1 to 4 meters, making maritime activities hazardous. A dry weather warning is also in effect for the eastern coast of Gangwon, eastern Jeollanam-do, Yeongnam, and parts of southern Chungcheong Province, increasing the risk of wildfires.

Air Quality and Health Considerations

While the warmer temperatures are welcome, air quality remains a concern. Until the morning of February 21st, fine dust concentrations are expected to be somewhat high in most areas due to the influence of foreign air pollution. The metropolitan area and Gangwon-do Yeongseo are expected to experience “bad” air quality levels, while Gangwon-yeongdong, Jeonnam, and Jeju are also forecast to have “bad” levels until dawn. Chungcheong, Gwangju, Jeonbuk, Daegu, and Gyeongbuk are also expected to experience “bad” air quality until morning. However, the National Institute of Environmental Research anticipates that southerly winds will begin to improve air quality starting in the southwestern region during the afternoon.

Individuals with respiratory sensitivities are advised to take precautions, such as wearing masks and limiting outdoor exposure during periods of high pollution. The daily temperature range is also expected to widen to around 15 degrees Celsius, particularly in the central inland and Yeongnam regions, which could impact health. Staying hydrated and dressing in layers are recommended to adjust to the fluctuating temperatures.

Looking Ahead: A Return to Cooler Temperatures

The mild weather is not expected to last. A continental high-pressure system moving east from China’s Shandong Peninsula will bring a return to cooler temperatures after the weekend. By February 23rd, the lowest morning temperature is forecast to be between -6 and 3 degrees Celsius, with daytime highs ranging from 3 to 13 degrees Celsius. This shift represents a return to more typical February conditions in South Korea. On February 24th, temperatures are expected to be between -4 and 6 degrees Celsius in the morning and 3 to 12 degrees Celsius during the day.

The Korea Meteorological Administration will continue to monitor the weather situation and provide updates as needed. Citizens are encouraged to stay informed about the latest forecasts and heed any safety advisories issued by local authorities. The fluctuating weather conditions underscore the importance of preparedness and caution during this transitional period.

The next official weather update from the Korea Meteorological Administration is scheduled for February 22nd at 6:00 PM KST, providing a more detailed forecast for the remainder of the week.
