Early Pollen Season Worsens Allergy Woes in South Korea
SEOUL, South Korea (2025-05-02) – While May is often celebrated for it’s pleasant weather and vibrant spring blooms, it also marks the peak of pollen season, bringing misery to allergy sufferers across South Korea. recent climate changes have exacerbated the problem, leading to earlier and more intense pollen dispersal, according to the Korea Meteorological Administration.
Earlier Pollen Release
The spring season, typically characterized by temperatures ranging from 61 to 70 degrees Fahrenheit in Seoul, is a prime time for outdoor activities and enjoying the colorful displays of cherry blossoms and other flowering trees. Though,these very trees are also significant contributors to airborne allergens.
Kim Sun-hee, a researcher at the National Institute of Forest Science’s Urban Forest Research Center, explained that trees release large amounts of pollen as part of their reproductive cycle. “The pollen is carried by the wind to fertilize other trees,” Kim said. “Birch, oak, and pine trees are among the species that release significant amounts of pollen in the spring, typically from late April through May, resulting in high pollen counts.”
Analysis by the Korea Meteorological Agency reveals that the pollen season is starting earlier than in previous years. A study of 11 cities across the country showed that the pollen season in the central region, including Seoul, Daejeon, and Gangneung, is starting up to five days earlier. The southern regions, including Daegu, Busan, and Jeonju, are experiencing a pollen season that begins up to seven days earlier.
In response to these changes, the korea Meteorological Administration updated its pollen calendar in 2019. The calendar is available on the Meteorological Agency’s website.
The pollen calendar varies significantly from year to year. Pollen observation shows that the type, timing, and amount of pollen differ by region. We create the calendar by averaging about 11 years of data. Spring,summer,and winter temperatures are rising,so the start date is getting earlier.
Kim Gyu-rang, a researcher at the Korea Meteorological Administration’s National Institute of Meteorological Sciences, said.
Increased Pollen Concentration
While the duration of the pollen season may be decreasing, the concentration of pollen in the air is increasing, particularly from common street trees like ginkgo.
Precautions for Allergy Sufferers
health officials advise individuals to take precautions during outdoor activities to minimize exposure to pollen. Recommendations include:
- wearing masks and sunglasses to prevent pollen from contacting the skin and eyes.
- Washing hands and face thoroughly after being outside.
- Avoiding outdoor exercise during dawn and morning hours, when pollen counts are typically highest.
