South Korea will experience clear skies and high temperatures during the final weekend of May, with some cities reaching 32 °C [1].
These conditions pose potential health risks due to elevated ozone levels and high ultraviolet radiation, particularly in southern regions. The weather pattern is driven by a dominant high-pressure system that is clearing the skies and increasing solar radiation across the peninsula.
In Seoul, temperatures were recorded at 23.3 °C during the morning broadcast [1]. The YTN News weather team said the city's temperature is expected to rise to 28 °C [1]. Weather caster Won Ida said that as the sun rises higher, temperatures are climbing rapidly [1].
Other regions are expected to see even higher peaks. Daegu is forecasted to reach 32 °C [1], while general daytime temperatures across the country will hover around 30 °C [2].
Officials warned that the combination of strong sunlight and clear skies will cause the UV index to surge. The YTN anchor said that UV levels will be very high, noting that some areas in Gwangju, Jeonnam, and Jeju will reach dangerous levels [1].
Residents are encouraged to take precautions against the heat and sun exposure. The forecast highlights a trend of rising temperatures compared to the previous day, with Seoul expected to be warmer than yesterday [1]. The high-pressure system remains the primary driver for this early summer warmth, creating a window of intense heat before the typical seasonal transitions.
“Seoul temperature is expected to rise to 28 °C.”
The convergence of a high-pressure system and late-May solar positioning creates a volatile environment for public health. When UV and ozone levels reach 'dangerous' thresholds in southern provinces like Jeju and Jeonnam, it increases the risk of heat exhaustion and skin damage, signaling an early onset of summer weather patterns for the region.
