Four Seasons of Korea, pleasant and beautiful
Korea is geographically situated in a temperate climate zone at medium latitude. As a result, it has four distinct seasons. In general, spring is from March to May, summer from June to August, autumn from September to November, and winter from December to February. The weather in spring and autumn is clear and dry due to the influence of anticyclones, the location of Korea on the North Pacific Edge makes summer hot and humid, and in winter, continental high pressure brings cold and dry weather.
>> Spring, Season of Budding Flowers
The spring season is usually between March and May. The warm weather causes trees and grass to bud, but the temperature can also vary greatly causing phenomenon like spring colds*(see below). The daily temperature range* varies greatly in the spring and the weather is dry*. The Asian dust phenomenon* and northeasterly winds* are most prominent during this time. Various flowers bloom in the mild and warm spring weather. Azaleas, forsythias, and royal azaleas are forerunners of spring in Korea. In April and May, the flowers are in full bloom, attracting people to mountains and parks. In rural areas, spring is the time to start planting rice, potatoes, sow vegetable seeds, and pruning branches of fruit trees.
- * Spring colds
Spring colds usually occur in early spring. This phenomenon is caused by the Siberian air mass rising in the winter, which lasts until early spring. Spring colds accompany strong winds and a significant drop in temperature, so it feels like the winter season is back. The phenomenon usually occurs two or three times in early spring.
- * Daily temperature range
The daily temperature range measures the difference between the lowest temperature in the morning and the highest temperature in the daytime. The range is usually high in the spring. The temperature range is even wider in the mountainous regions of Gangwon-do Province where the morning temperature goes down to around -2 degrees Celsius and the daytime temperature rises to as high as 17 to 18 degrees Celsius.
Spring is a dry season in Korea. The weather is particularly dry in early April and there are many mountain fires during this period. The weather is mostly affected by the air mass from the Yangzi River, which is separated from the Siberian air mass. This phenomenon is known as a migratory anticyclone, which brings clear and dry weather.
- * Asian dust phenomenon
In the spring, sandy dusts are carried by wind from the Gobi Desert and fly as far as Korea. When the National Weather Service predicts severe Asian dust, people are advised to wear masks as to protect from possible eye or respiratory irritation.
- *Northeasterly wind
Also called Foehn, the Northeasterly wind is a hot and dry local wind rising from valleys between late spring and early summer. When the humid and cold wind from the East Sea ascends the Taebaeksanmaek Mountain Range, the temperature falls. After pouring rain on the mountains, the wind loses its moisture and as the wind descends the other side of the mountain, it turns hot and dry. Due to the heat and dryness of the wind, the regions west of the Taebaeksanmaek Mountain Range sometimes face damages to their agricultural crops.
