According to climate analysis data from Yonhap News Agency and the Korea Meteorological Administration on the 6th, the number of days with thunder and lightning last month, which even caused casualties from lightning strikes, was 3.5 days (average of 13 observation points), higher than the average of 1.9 days and the highest ever recorded. Additionally, there were 12 days when thunder and lightning were observed at least at one of the 13 observation points.

Last month, the nationwide average temperature was 22.3 degrees Celsius. Since the expansion of the national weather observation network in 1973, which serves as the basis for various weather records, this was the fourth highest average temperature for June. It was 0.9 degrees higher than the average June temperature of 21.4±0.3 degrees Celsius for the normal period (1991?2020).

In the early part of last month, warm air flowed in from inland China and Mongolia via westerly winds. In mid-June, the weather was clear due to a mobile high-pressure system, and in late June, temperatures rose as southwesterly winds blew along the edge of the North Pacific High.

The nationwide average number of heatwave days and tropical nights last month were 0.9 days and 0.1 days respectively, both higher than the normal averages of 0.7 days and 0 days.

On the 26th, tropical nights typical of June appeared in Miryang, and on the 28th in Seoul, Cheongju, Gangneung, and Sokcho. Seoul experienced a June tropical night for the second consecutive year after first experiencing it last year.

The nationwide average precipitation last month was 208.9 mm, exceeding the normal range of 101.6 to 174.0 mm. This ranked 11th highest on record. This was due to the monsoon rains starting on the 25th from Jeju and the southern regions. The precipitation in late June (178.2 mm) was the third highest for late June on record.
