Overall it will always be HOT AND HUMID on the trail in August. It is not the best time or enjoyable time for walking. Please consider postponing until September.

Jeju, sunny and hot weather…Expect a maximum of 36 degrees during the day

The Jeju Regional Meteorological Administration predicted that the highest temperature during the day would reach 30-36 degrees with heat warnings in the north and east of Jeju and warnings of heat in the south and west.
According to the Meteorological Administration, the highest daytime temperature in Jeju (northern) on the previous day reached 36.1 degrees, the highest this year.
An official from the Meteorological Agency said, “There may be places where the minimum temperature is maintained above 25 degrees Celsius until 9 am on this day, and tropical nights appear at night, and even during the day it will be hot, such as 36 degrees Celsius.
“He added, “Because there are places where the wind blows strongly at 9 to 13 meters per second in the mountains of Jeju, and there could be fog around the coast of Jeju, you should be careful about safety accidents.” Source: https://www.yna.co.kr/view/AKR20200814010700056?input=1195m

The average temperature in June was higher than in July… The first in history of observation (Nationwide)

For the first time this year’s meteorological observations, a ‘reversal phenomenon’ appeared, where the average temperature in July was lower than in June. A premature heatwave came in June, and July saw the result of the rainy season and other effects.

Also, from June to early August, it was found that the precipitation was the second highest ever.   According to the explanatory data of ‘The Current Status of Korea’s Abnormal Climate and Global Climate Prospects’ released by the Climate Change Monitoring Division of the Meteorological Administration’s Climate Change Monitoring Division on the 13th, the average temperature in June was high due to an early heatwave.

It ranked first in history, but July was very cool and ranked 44th in all time.  

Records began in 1973.

Accordingly, the average temperature for this year in July (22.7 degrees) was lower than that in June (22.8 degrees).  

The usual average temperatures in June and July are 21.2 degrees and 24.5 degrees Celsius, respectively. The average temperature from January to July this year was 12.7 degrees Celsius, which is the third highest ever (11.6 degrees per year). 

Unlike Korea, which is jagged, the world’s average temperature from January to June was the second highest in history, consistently maintaining a high level with no significant difference from month to month.

From June 1st to last 10th, the national precipitation in summer was 879.0mm, which was higher than the average (470.6~604.0mm), ranking second. In 2011, the year with the highest precipitation in the country in summer was 942.2 mm. This year, the rainy season in Central and Jeju recorded the longest rainy season with 54 days (at the end of the 16th) and 49 days.  

The amount of precipitation from January to the 10th was 1193.5mm, which is the third place in history. Compared to the average 825.9 mm, it is about 44.5% more. The Meteorological Administration explained that the temperature of last month was low as the air in the upper and lower atmosphere around Korea was stagnant from the end of last June.

In addition, due to the delay in the expansion of high pressure in the warm and humid North Pacific Ocean, congested fronts with narrow widths to the north and south moved up and down Korea due to the encounter with the cold air in the north, and the rainy season continued with torrential rain.

This phenomenon is due to the occurrence of a high temperature phenomenon in the Arctic. As the strong wind (jet air flow) flowing through the upper atmosphere weakened, the fluctuations of the mid-latitude barometer increased.

At this time, high pressure zones developed in the Ural Mountains and northeastern China, slowing the east-west flow, creating favorable conditions for the continuous cold air to be located around Korea.

The high temperature in the Arctic is due to the heat wave caused by the high temperature phenomenon in Siberia while the high pressure separated from the blocking (actually stationary high pressure) that occurred in East Siberia at the end of June stagnated in the North Pole.

The meteorological agency analyzed that it was caused by a sharp decline and increased heat supply from the ocean to the atmosphere.
