This year’s Korean rainy season, known as jangma in Korean, just started.
Jangma started in Jungbu (Central Region) on the night of June 17, and is expected to move southward steadily as it rains throughout the country on June 18 and 19. The most surprising aspect of this year’s jangma is that it started in the Jungbu Region and not on Jeju Island where it usually does, an occurrence that has not happened for 32 years.
This year’s starting date arrived twelve days sooner than last year and a week sooner than the yearly average. The rainy season tends to last for one month and is often paired with the summer heat.
Visitors planning to visit Korea during the rainy season are advised to check the weather forecast frequently.
