Typhoon Champy Weakens: South Korea Faces Cold Snap

Typhoon Champy, the 30th typhoon of the season, has weakened into an extratropical cyclone after approaching waters south of Jeju Island early on October 26, 2026. While the storm has lost its original intensity, it continues to bring strong winds and heavy rainfall to coastal regions, with a significant drop in temperatures expected across South Korea by mid-week.

Why it is trending now

As of October 26, 2026, search interest is high as residents track the impact of the storm and prepare for an incoming cold front. Although the typhoon has dissipated, weather authorities have maintained warnings for strong winds and high waves in several coastal areas. The transition from typhoon conditions to a sharp autumn cold snap has prompted widespread public attention.

Key facts

• According to MBC News, Champy is the latest-forming 30th typhoon since records began in 1951.
• The Korea Meteorological Administration reported that Jeju Island received over 300mm of rain over three days due to the storm's indirect influence.
• YTN reports that despite the weakening of the storm, wind speeds in coastal areas like Yeosu have reached 30 meters per second.
• Wind and wave advisories remain in effect for parts of the southern and western coasts.

Why this is trending in South Korea

The sudden shift from typhoon-related weather to a forecast of 2°C morning temperatures in Seoul has made the weather a primary concern for the public. Residents are actively searching for information to prepare for the rapid drop in temperature and lingering wind hazards.

Background and context

Typhoon Champy moved toward the Korean Peninsula late in the season, losing its tropical characteristics before making landfall in Japan. While the storm did not strike the peninsula directly, its indirect influence caused flight delays, ferry cancellations, and localized damage in Jeju and southern coastal regions. The current cold snap is driven by cold air moving in from the northwest.

What happens next

Temperatures are expected to decline significantly starting tomorrow, with Seoul's morning low predicted to hit 2°C on October 28. Authorities advise caution regarding facility management due to strong winds. Additionally, another round of rain is expected to affect the country on Thursday and Friday, followed by further cooling over the weekend.
