In 2024, the average maximum temperature in South Korea reached 19.7 degrees Celsius, slightly higher than the previous year. The annual average maximum temperature in South Korea has risen steadily over the measured period. Temperature trends by season South Korea has four seasons, each characterized by its own distinctive temperature trends. The average summer temperature recorded in South Korea has ranged from 23 to 25 degrees Celsius. Although average temperatures generally indicate moderate warmth, 31 heat-wave days were recorded in 2018 alone, far above the average value. Conversely, winter in South Korea is the coldest and driest season, with an average temperature of about 2.4 degrees Celsius in 2023. Climate change and response Climate change has impacted South Korea. Despite the minor ups and downs in temperature, the annual average temperature has moved gradually upward, showing a difference of more than one degree Celsius from 2023 to 1973. Additionally, the number of heatwave days has increased substantially compared to previous decades. This has not gone unnoticed, as most legislative members of the National Assembly have identified addressing the enactment and revision of policies as a priority in responding to the climate crisis.

In 2024, the average minimum temperature in South Korea was 9.9 degrees Celsius. This was the highest temperature since 1973. The annual average minimum temperature in South Korea has risen steadily during the measured period.

In May 2025, the average temperature in Jeju, South Korea, was 17.5 degrees Celsius. The island's hottest month was August 2024, while February 2022 was the coldest, with an average temperature of 5.2 degrees Celsius.

In May 2025, the average temperature in Busan, South Korea was 17.4 degrees Celsius. August 2024 was the city's hottest month in the past five years, while February 2025 was the coldest, with an average temperature of 2.9 degrees Celsius.

Temperature in North Korea increased to 8.33 celsius in 2024 from 8.07 celsius in 2023. This dataset includes a chart with historical data for North Korea Average Temperature.

In 2023, the average fall temperature in South Korea was around 15.1 degrees Celsius, up from 14.8 degrees Celsius in the previous year. The highest temperature since 2000 was 15.2 degrees Celsius in 2019, while the lowest temperature was 12.2 degrees Celsius in 2002.

The average temperature in South Korea in 2024 was 14.9 degrees Celsius. The average temperature in South Korea has risen steadily over the years, which is shown in the graph. Extreme weather South Korea has a distinct four-season climate. Generally, summer in South Korea is humid and hot, while winter is dry and cold. However, the summer climate, which usually lasts from June to August, is getting longer and can last from May through to September. Especially in summer, extreme weather such as tropical nights, typhoons, and heatwaves occur. Recently, there was an increase in the consecutive days in which heatwaves reached temperatures above 33 degrees. Greenhouse gas emissions South Korea is suffering from air pollution problems, such as yellow dust and fine dust, that have increased rapidly over recent years. In addition, as the carbon dioxide concentration has continued to rise, the average annual temperature has also risen steadily, resulting in abnormal climates, such as heatwaves in summer or extreme cold in winter. South Korea is one of the countries that produces a lot of greenhouse gases. Due to the manufacturing-oriented industrial structure, greenhouse gas emissions from energy use account for a large portion.

In May 2025, the average temperature in Ulsan, South Korea, was 17 degrees Celsius. The city had its hottest month in the past six years in August 2024, while February 2025 was the coldest month with an average temperature of 1.9 degrees Celsius.

In 2023, the average spring temperature in South Korea was around 13.5 degrees Celsius, up from 13.2 degrees Celsius in the previous year. It was the highest temperature since 2020, while the lowest temperature was 10.6 degrees Celsius in 2010.

In 2018, South Korea recorded its hottest summer since 1973, with 31 heat-wave days. Heatwaves with maximum temperatures above 33 degrees Celsius usually occur after the rainy season in summer. In recent years, not only has the frequency of heatwaves increased, but also their intensity. Summer in South Korea Summer in South Korea (from June to August) is usually hot and humid with a lot of rainfall during the rainy season of the East Asian monsoon (Changma). About 60 percent of precipitation falls during this season. The average temperature in summer was around 24.7 degrees Celsius in 2023. The amount of precipitation in summer that year stood at over 1,000 millimeters, more than four times higher than in winter. Climate change South Korea is known for its four distinct seasons, yet weather patterns have increasingly changed in recent decades, resulting in longer summers and shorter winters. This shows that South Korea is not excluded from the effects of climate change. Changing climate patterns in recent decades have also led to an intensification of precipitation and more heat waves in South Korea. Meanwhile, climate change is taken very seriously by South Koreans: about 48 percent of respondents to a 2019 survey said that global warming or climate change is the most important environmental issue for South Korea.

In 2023, the average summer temperature in South Korea was around 24.7 degrees Celsius, up from 24.5 degrees Celsius in the previous year. The highest temperature since 2000 was 25.3 degrees Celsius in 2018, while the lowest temperature was 22.2 degrees Celsius in 2003.

A mid-term forecast is a forecast that is announced by dividing the weather outlook, land and sea weather, highest and lowest temperatures, and wave heights for up to 11 days following the short-term forecast, into morning and afternoon (daily for 8-10 days).
