Incheon - When to Visit

When to Visit Incheon

Year-round climate guide & best times to travel

Incheon experiences a humid continental climate with four distinct seasons, characterized by hot, humid summers and cold, dry winters. The city follows the typical Korean weather pattern with a monsoon season from late June through August, bringing heavy rainfall and high humidity. Spring (March-May) and autumn (September-November) are considered the most pleasant seasons, offering mild temperatures, lower humidity, and beautiful seasonal changes with cherry blossoms in spring and colorful foliage in fall. Winter temperatures can drop well below freezing with occasional snowfall, while summers can be quite hot and muggy with temperatures reaching into the 30s°C (high 80s-90s°F). The monsoon season accounts for about 60% of the annual precipitation, making summer months wet and humid. The coastal location moderates temperatures slightly compared to inland areas, but also increases humidity levels throughout the year.
