May 1, Labor Day and the start of a long holiday stretch, is expected to be mostly sunny and mild. Skies are forecast to clear gradually from western areas in the morning, making conditions suitable for outdoor activities.
Yonhap reported Thursday that temperatures will be near seasonal norms, with morning lows of 8 to 12 degrees Celsius and daytime highs of 18 to 26. Seoul is expected to reach 26, with Daejeon at 23 and Daegu at 24. Inland areas will see a large day-to-night swing of about 15 degrees, requiring extra care for health.
Ozone levels are also a concern. The National Institute of Environmental Research forecast “bad” ozone levels across most regions, including Gyeonggi, Chungcheong, Honam, Yeongnam and Jeju. Air quality could worsen late in the afternoon as ozone flows in from outside the country.
Dry conditions and strong winds will persist. Dry weather alerts are in effect for Seoul, Chungcheong and inland North Gyeongsang Province. Gusts of about 55 kilometers per hour are expected across inland areas, the East Sea coast and Jeju, raising the risk of fires. The strong winds are forecast to continue through May 2.
The holiday forecast is expected to shift. May 2 will be similar to May 1, but rain is likely nationwide on May 3 under the influence of a low-pressure system.
At sea, fog is expected May 1-2, especially in the central Yellow Sea, sharply reducing visibility in some waters. From May 2, sea levels are also expected to rise, and low-lying coastal areas should prepare.
