On Tuesday, May 19, early summer weather is expected to continue across the country, with heat intensifying. In particular, daytime temperatures are forecasted to exceed 30 degrees Celsius, especially in the Gyeongsang region, necessitating caution for health management.

According to the Korea Meteorological Administration, the morning low temperatures nationwide are expected to range from 14 to 20 degrees Celsius, while daytime highs will be between 24 and 33 degrees Celsius.

In Daegu and southern Gyeongbuk, the maximum perceived temperature may rise to around 31 degrees Celsius, indicating a hot midday. However, temperatures are expected to drop quickly after sunset, resulting in a significant temperature difference of about 15 degrees Celsius, so appropriate clothing choices are advised.

The sky will be partly cloudy nationwide, gradually becoming overcast from the evening. Thanks to favorable atmospheric dispersion, fine dust levels are expected to remain at 'good' to 'moderate' levels across all regions, making outdoor activities manageable.

Sea conditions will be relatively calm across all waters. In the East Sea, wave heights will be between 0.5 and 1.0 meters, while in the West Sea and South Sea, wave heights will remain around 0.5 meters. In the offshore waters, wave heights will be 0.5 to 1.0 meters in the East Sea and 0.5 to 1.5 meters in the West and South Seas.
