Temperature records for the past 69 years

The hottest temperature measured from 1951 to October 2020 was reported by the Chuncheon weather station. In August 2018, the record temperature of 39.5 ° C was reported here. The hottest summer from July to September, based on all 9 weather stations in South Korea below 90 meters above sea level, was recorded in 1994 with an average of 25.9 ° C. This average temperature is usually recorded every 4 to 6 hours, including the nights. Normally this value is 24.0 degrees Celsius.

The Chuncheon weather station reported the coldest day in these 69 years. Here the temperature dropped to -24.5 ° C in January 2001. Chuncheon lies at an altitude of 79 meters above sea level. The coldest winter (January to March) was in 1951 with an average temperature of -0.6 ° C. In South Korea it is usual to have about 3.9 degrees more at 3.3 ° C for this three-month period.


Long-term development of temperatures from 1990 to 2019

In contrast to individual record values, a long-term development cannot simply be brought about over all weather stations in the country. Both the number and the locations are constantly changing. A simply calculated average value would produce a falsified result. If several measuring stations are added in a year in particularly cold mountain or coastal regions, this alone would reduce the average. If a station fails over the summer or winter months, it does not provide any values ​​and falsifies the average again. The subsequent long-term development was therefore reduced to only 3 measuring points in order to actually have comparable data over the longest possible period.

In the years 1990 to 2019 there were only these 3 weather stations in the whole country, which continuously reported temperature values ​​(Gangneung, Busan, Mokpo). From these weather reports we have created a long-term development that shows the monthly average temperatures. The hottest month in this entire period was 1994 with 28.1 ° C. 2011 was the coldest month with an average of -1.9 ° C.

The annual average temperature was around 14.1 ° C in the years after 1990 and around 14.6 ° C in the last years before 2019. In other words, it has increased moderately by around 0.5 ° C over the past 30 years. However, this tendency only applies to the selected 3 weather stations in South Korea. We have provided a considerably more extensive evaluation of the global temperature rise separately.
