It's hot as if the whole country went into a sauna.
As hot, humid air continues to flow into the rim of the North Pacific High Pressure, strong sunlight is expected during the day.
A heat wave warning has been issued for most of the country, and in many places the temperature has exceeded 30 degrees in the morning.
Considering that the average high temperatures in Seoul and Seongnam as of July 2 are 27.7 degrees and 28.8 degrees, the temperature is 4-5 degrees higher than normal midday, appearing before 10 am.
In Daegu and Yeongdeok-gun, Gyeongsangbuk-do, the current temperature is 32 degrees.
Daytime highs are expected to be between 28 and 36 degrees, the highest between 9 a.m. and 6 p.m.
It is predicted that the daytime temperature will rise to 36 degrees in Daegu, 35 degrees in Gwangju, 34 degrees in Daejeon, and 33 degrees in Seoul and Ulsan.
Gwangju, Jindo-gun, Jeollanam-do, Jeju-si, and Seogwipo-si have the highest UV index, which is 'dangerous'.
As the temperature rises during the day, there will be showers throughout the inland area from the afternoon to the evening.
