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 the frequency of heatwaves has 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 over one meter, 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 heatwaves 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.

In September 2024, the average temperature in Incheon, South Korea was 25.4 degrees Celsius. August 2024 was the city's hottest month in the past five years, while December 2022 was the coldest, with an average temperature of minus 2.6 degrees Celsius.

In September 2024, the average temperature in Busan, South Korea was 26.7 degrees Celsius. August 2024 was the city's hottest month in the past five years, while January 2021 and December 2022 were the coldest, with an average temperature of 3.3 degrees Celsius.

In September 2024, the average temperature in Jeju, South Korea was 27.6 degrees Celsius. The island's hottest month was August 2024, while February 2022 was the coldest, with an average temperature of 5.6 degrees Celsius.

In 2023, precipitation in Gyeongnam Province in South Korea was the highest nationwide, with about 2,084 millimeters. Jeonbuk followed with around 1,980 millimeters.

In September 2024, the average temperature in Gwangju, South Korea was 26.3 degrees Celsius. August 2024 was the city's hottest month in the past five years, while December 2022 was the coldest, with an average temperature of 1.1 degrees Celsius.

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. In general, summer in South Korea is humid and hot, and 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 throughout 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 producing a lot of greenhouse gases. Due to the manufacturing-oriented industrial structure, greenhouse gas emissions from energy use accounts for a large portion.

Understanding climatic effect on wildlife is essential to prediction and management of climate change’s impact on the ecosystem. The climatic effect can interact with other environmental factors. This study aimed to determine effects of climate and altitude on Siberian roe deer (Capreolus pygargus) activity in temperate forests of South Korea. We conducted camera trapping to investigate roe deer’s activity level from spring to fall. Logistic regressions were used to determine effects of diel period, temperature, rain, and altitude on the activity level. A negative relationship was noted between temperature and the activity level due to thermoregulatory costs. Roe deer activity exhibited nocturnal and crepuscular patterns during summer and the other seasons, respectively, possibly due to heat stress in summer. In addition, the effect of temperature differed between high- and low-altitude areas. In low-altitude areas, temperature affected negatively the activity level throughout the study..., The camera trapping method was used to observe temporal variations in roe deer capture (sampling days: September to October 2021 and April to August 2022). In the study area, a 5 × 6 grid design (interval = 600 m) was established, and one trail camera (Spec Ops Elite HP4; Browning Co., USA) was deployed corresponding to each cell of the grid. The study period was divided into five seasons, and further analyses were performed for each season: spring (15 April to 15 May, 960 trap-days), early summer (16 May to 30 June, 1380 trap-days), summer (1 July to 31 August, 1860 trap-days), early fall (September, 900 trap-days) and fall (October, 810 trap-days). The camera-plot altitudes were categorised into four classes: 600 (600–800 m asl, n = 3), 800 (800–1,000 m asl, n = 10), 1,000 (1,000–1,200 m asl, n = 11) and 1,200 (1,200–1,400 m asl, n = 6). We created a roedeer variable as presence/absence of observation per 2-h in each altitude class. In order to account for sampling effort depending on..., , This README file was generated on 2023-09-22 by Tae-Kyung Eom.

In 2023, the average temperature for summer in South Korea was 24.7 degrees Celsius. South Korea has four distinct seasons, which can be seen in the different average temperatures for each season.

Oysters are a major commercial and ecological fishery resource. Recently, the oyster industry has experienced mass mortality in summer due to environmental factors. Generally, the survival of oysters in aquatic environments is mainly impacted by environmental stressors such as elevated sea temperatures and reduced salinity; however, the stressors impacting tidal flat oysters that are repeatedly exposed to air remain poorly understood. Hence, we studied the relationship between environmental factors and the survival of tidal flat pacific oysters in Incheon, South Korea, where mass mortality is common. Principal component analysis and Bayesian networks revealed that air temperature (in spring and summer) and sea temperature (in summer) are related to oyster production. In habitats of the tidal flat oysters during the summer, high temperatures of 34.7–35.4°C (maximum 47.6°C) were observed for average durations of 0.8–1.9 hours (maximum 3.6 hours). Furthermore, heat waves occurred for up to 12 consecutive days. Results from the multiple stress test showed that when exposed to 45°C (air temperature) for 4 hours per day, the survival rate of oysters was 42.5% after only 2 days and 0% after 6 days. The findings stemming from the field observations and stress tests suggest that high temperatures during emersion may contribute to mass mortality of oysters in summer, indicating a potential threat to oysters due to climate change. To understand the effects of future thermal stress on oysters more accurately, simultaneous long-term trend analyses and field-based observations are required.

In 2023, the average maximum temperature in South Korea reached 19.2 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 history of average summer temperature recorded in South Korea has ranged around 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 0.2 degrees Celsius in 2022. 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 found addressing the enactment and revision of policies to be a priority for responding to the climate crisis.
