Jeju’s second tropical night this year… and record breaking rainy season length

During the rainy season, the Jeju Island had a tropical night. This is the second in 2020.

According to the Meteorological Administration on the 27th, the lowest temperature in Jeju was recorded at 25.1 degrees during the night, and a tropical night was observed. In Seongsan, the lowest temperature was 25.3 degrees.

The Korea Meteorological Administration considers it to be a tropical night if the minimum temperature does not drop below 25 degrees from 6 p.m. on the previous day to 9 a.m. on the following day.

On this day, as the rain fell weak during the night, all the heavy rains warning on the mountain at 6:10 am were lifted.

Precipitation at 6 am was 87.5 mm on the tripod peak of Halla Mountain, 70.5 mm on the rhododendron field.

By this morning, it will rain more in the southern and western mountain area. Depending on where it is produced, it is possible that it will rain more by afternoon.

Rivers and valleys can suddenly blow in a short period of heavy rain, so campers such as mountains and valleys must take special care.

Tomorrow (29th) will occasionally rain from morning to day, mainly in mountainous regions affected by topography. When the rain stops, the rainy season is expected to end.

The rainy season, which began on June 10th, continues on the 49th day until today. This is the longest record ever since 47 days recorded in 1973.

The number of precipitation days during the rainy season is also the longest. The average number of precipitation days since June 10 is 30 days. Today’s precipitation was replaced by 29.5 days of the longest precipitation in 1974.
