The Third Battle of Seoul, also known as the Chinese New Year's Offensive, the January–Fourth Retreat (Korean: 1•4 후퇴) or the Third Phase Campaign Western Sector (Chinese: 第三次战役西线; pinyin: Dì Sān Cì Zhàn Yì Xī Xiàn), was a battle of the Korean War, which took place from December 31, 1950, to January 7, 1951, around the South Korean capital of Seoul. In the aftermath of the major Chinese People's Volunteer Army (PVA) victory at the Battle of the Ch'ongch'on River, the United Nations Command (UN) started to contemplate the possibility of evacuation from the Korean Peninsula. Chinese Communist Party chairman Mao Zedong ordered the Chinese People's Volunteer Army to cross the 38th Parallel in an effort to pressure the UN forces to withdraw from South Korea. On December 31, 1950, the Chinese 13th Army attacked the Republic of Korea Army (ROK)'s 1st, 2nd, 5th and 6th Infantry Divisions along the 38th Parallel, breaching UN defenses at the Imjin River, Hantan River, Gapyeong and Chuncheon in the process. To prevent the PVA forces from overwhelming the defenders, the US Eighth Army now under the command of Lieutenant General Matthew B. Ridgway evacuated Seoul on January 3, 1951. Although PVA forces captured Seoul by the end of the battle, the Chinese invasion of South Korea galvanized the UN support for South Korea, while the idea of evacuation was soon abandoned by the UN Command. At the same time, the PVA were exhausted after months of nonstop fighting since the start of the Chinese intervention, thereby allowing the UN forces to regain the initiative in Korea.

The climate of Seoul features a humid continental climate with dry winter, called "Dwa" in the Köppen climate classification. Seoul is classed as having a temperate climate with four distinct seasons, but temperature differences between the hottest part of summer and the depths of winter are extreme.

In winter the city is topographically influenced by expanding Siberian High-pressure zones and prevailing west winds, temperatures dropping almost as low as -20 °C (-4 °F) in severe cold waves. The bitterly cold days tend to come in three-day cycles regulated by rising and falling pressure systems.

Most of Seoul's precipitation falls in the summer monsoon period between June and September, as a part of East Asian monsoon season.
