Sunny weather returned to Seoul and western and eastern regions of South Korea this Friday, triggering a rapid increase in temperatures.
The sudden shift to early-summer conditions follows a period of gray skies and rain, signaling a sharp transition in the regional seasonal pattern.
Daytime temperatures in most regions rose by five to seven degrees Celsius [1] this afternoon. On the east coast, high temperatures reached the mid-to-upper teens in degrees Celsius [1]. This warmth is building quickly as sunshine replaces the previous overcast conditions.
Forecasts indicate that the warming trend will continue through the coming days. Temperatures in Seoul are expected to hit 30°C by Monday [1].
Other projections suggest even higher peaks later in the week. Some reports indicate temperatures could reach near 90°F, or approximately 32°C, by Thursday [2]. These breezy conditions are expected to persist as the summer-like warmth takes hold across the western parts of Korea and the capital region.
The transition from rain to high heat occurs as the region moves out of a volatile weather pattern. Residents are seeing a swift climb in mercury levels that deviates from typical gradual spring warming.
“Daytime temperatures in most regions rose by five to seven degrees Celsius this afternoon.”
The rapid temperature spike suggests a volatile transition into the summer season for South Korea. The discrepancy between forecasts—ranging from 30°C on Monday to 32°C by Thursday—indicates a continuing upward trajectory of heat that may put early pressure on urban infrastructure and public health systems in Seoul.
