Labor Day on May 1, 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 generally suitable for outdoor activities.
According to Yonhap on April 30, temperatures are expected to be near seasonal norms, with morning lows of 8-12 C (46-54 F) and daytime highs of 18-26 C (64-79 F). Seoul is expected to reach 26 C, with Daejeon at 23 C and Daegu at 24 C. Inland areas are expected to see large day-to-night swings of around 15 C, calling for caution with health management.
Ozone levels also warrant attention. The National Institute of Environmental Research forecast “bad” ozone levels in most regions, including Gyeonggi, Chungcheong, Honam, Yeongnam and Jeju. Air quality could worsen from late afternoon as ozone flows in from outside the country.
Dry conditions and strong winds are expected to persist. Dry weather advisories are in effect for Seoul, Chungcheong and inland North Gyeongsang Province. Strong gusts of about 55 kph (34 mph) are forecast across inland areas, the East Sea coast and Jeju, raising the risk of fires. The strong winds are expected to continue through May 2.
Holiday weather is expected to shift. May 2 is forecast to 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 over the central West Sea on May 1-2, sharply reducing visibility in some waters. From May 2, sea levels are also expected to rise, and low-lying coastal areas should prepare.
