Get your umbrellas ready, because the monsoon season has returned to Korea. During this monthlong span, some places will receive up to 400 millimeters of rain.

Usually, the monsoon season starts in late June, with heavy downpours initially hitting Jeju Island. Then, the seasonal rain front gradually moves northward and arrives in Seoul and its surrounding areas. In 2024, monsoon rainfall started on June 29th, but this year, it already arrived in Jeju Island on June 12th.

The monsoon season in Korea is known for bringing high humidity and heavy showers. These sudden downpours are also known as guerrilla rain because they can begin without warning and cause great damage in a short time. Meteorologists say this year’s monsoon season is likely to include many sudden and strong rainstorms.

Last summer, the rainy period extended until September, lasting longer than usual. In areas like the Jeolla Provinces, precipitation reached over 100 millimeters per hour, causing flash floods and major property damage. Roads and houses were flooded, and some residents were forced to evacuate affected regions.

Prior to this year’s monsoon season, the government prepared by inspecting infrastructure, such as drainage systems, roads, and areas on slopes. It also shared evacuation tips and natural disaster safety guidelines with the public.

Furthermore, people are advised to carry umbrellas, wear waterproof shoes, and avoid rivers or low-lying areas in the coming month. Staying alert to weather reports and emergency announcements is also crucial for everyone’s safety during this rainy season.
