Vernal Equinox Brings Warmer Weather Across South Korea

Today, March 20, 2025, marks the vernal equinox, a day recognized for its equal lengths of day and night, symbolizing the onset of spring. As the sun rises higher, temperatures across South Korea are expected to increase significantly, bringing a welcome change from the recent cold spell.

This morning, the temperature in Daegu started at a chilly -0.7 degrees Celsius; however, by the afternoon, it will rise to a pleasant 17 degrees Celsius. Other regions are experiencing similar changes, with Seoul expected to reach 14 degrees Celsius, a noticeable jump from yesterday's high of 7.3 degrees Celsius, according to reports.

As spring blossoms, pollen levels are set to rise, complicating matters for allergy sufferers. The daily temperature variations are particularly significant this time of year, potentially exceeding 15 degrees Celsius. This fluctuation between warm afternoons and cool mornings requires residents to dress accordingly.

Air quality is another concern as fine dust from overseas begins to infiltrate the atmosphere, particularly affecting the western regions. The forecast indicates that cities like Seoul, Daejeon, and Daegu will experience poor air quality today, exacerbated by the influx of ultrafine dust. As a precaution, health officials advise those with respiratory issues to exercise extra caution.

The Meteorological Administration has warned that although temperatures are rising, the strong winds expected — particularly along the East Sea — could reach gust speeds of 20 to 25 m/s. A strong wind advisory is currently in effect, warning of potential hazards.

In the central inland areas, the sky is partly cloudy, but the rest of the nation is expected to enjoy mostly clear skies today. Morning lows across the country range from -4 to 3 degrees Celsius, while highs will reach between 11 and 17 degrees Celsius.

Seoul is forecasted to have a high of 14 degrees Celsius today; exceptional warmth is anticipated over the weekend, with temperatures expected to soar to 21 degrees Celsius by Sunday, March 23, confirming the arrival of spring.

As conditions warm up, it's vital to remain vigilant about fire hazards, especially in the eastern regions, where drier air has elevated the risk of wildfires. The waves in the coastal areas of the East, West, and South Seas are predicted to be moderate, with heights ranging from 0.5 to 2.0 meters inshore and slightly higher offshore.

In summary, March 20 heralds a significant transition as the vernal equinox ushers in warmer weather across South Korea. Despite the beautiful springtime conditions, the combination of rising temperatures and environmental factors like air quality and wind can pose challenges. Residents are encouraged to enjoy the emergence of spring while taking necessary precautions.
