On Saturday, May 30, clear skies are expected across the country, with daytime temperatures rising significantly, leading to early summer heat. Daegu is forecasted to reach a high of 32 degrees Celsius, with notable warmth particularly in the Gyeongsang region.

According to the Korea Meteorological Administration on May 29, the weather on May 30 will be influenced by high pressure moving eastward over the Yellow Sea, resulting in generally clear conditions nationwide. While there are no significant rain forecasts, strong sunlight will cause inland temperatures to rise above average.

Morning lows are expected to range from 12 to 19 degrees Celsius, while daytime highs will be between 25 and 32 degrees. Compared to the average morning lows of 11 to 16 degrees and daytime highs of 22 to 27 degrees, morning temperatures will be similar or slightly higher, and daytime temperatures will be elevated nationwide. Due to the significant temperature difference between day and night, residents should take care of their health.

Morning lows in major cities are forecasted as follows: Seoul 16 degrees, Incheon 16 degrees, Suwon 14 degrees, Chuncheon 14 degrees, Gangneung 19 degrees, Cheongju 15 degrees, Daejeon 14 degrees, Jeonju 15 degrees, Gwangju 14 degrees, Daegu 15 degrees, Busan 17 degrees, Ulsan 16 degrees, and Jeju 17 degrees.

Daytime highs are expected to be: Seoul 28 degrees, Incheon 26 degrees, Suwon 27 degrees, Chuncheon 29 degrees, Gangneung 31 degrees, Cheongju 30 degrees, Daejeon 29 degrees, Jeonju 28 degrees, Gwangju 29 degrees, Daegu 32 degrees, Busan 29 degrees, Ulsan 30 degrees, and Jeju 26 degrees.

Particularly in the Gyeongsang region, many areas will see daytime temperatures exceed 30 degrees. With humidity factored in, the perceived temperature could rise to around 31 degrees, necessitating adequate hydration for those engaging in outdoor activities for extended periods.

Fog that persisted overnight will mostly dissipate, but some sea fog may linger over the Yellow Sea and around Jeju Island until morning. Vessels navigating or fishing in these areas should exercise caution for maritime safety.

Waves are expected to reach heights of 0.5 meters in the Yellow Sea, 0.5 to 1.0 meters in the South Sea, and 0.5 to 1.5 meters in the East Sea.

Air quality is expected to be at a level ranging from 'good' to 'moderate' across all regions. Some areas in the central and western parts of the country may experience temporarily elevated levels of foreign fine dust in the early morning, but conditions are expected to improve as atmospheric dispersion becomes more favorable throughout the day.
