YES — Seoul lowest temperature on April 30 will be 13C. wttr.in/Seoul reports: current temp 21C, sunny, humidity 28% (very dry). Forecast low for today: 13C (56F), high 23C. Low humidity of 28% enables strong radiative cooling overnight with clear skies, supporting the lower end of the temperature range. The current sunny and dry conditions confirm no cloud cover to trap nighttime heat. A dry clear-sky spring night in Seoul with a forecast low of 13C is meteorologically consistent. Counterargument: urban heat island effect and residual daytime heat could keep temps above 13C into the 14-15C range — discounted because the extremely low humidity (28%) accelerates nocturnal cooling more than UHI can compensate. The wttr.in forecast of 13C low is the best available estimate.
