Peak UV
6.8 at 오후 12:00
UV and heat are separate hazards; the lowest-heat hour may still need sun protection.
Tomorrow's direction
1°C hotter tomorrow
Today's forecast range is 20°C–24°C.
Where these numbers come from
WeatherAPI supplies the forecast. HeatGuard calculates heat-index risk and models WBGT from forecast temperature, humidity and a daytime solar allowance. Modeled WBGT is not an on-site globe-thermometer reading.
Local planning context
Planning for heat in Seoul, South Korea
Seoul's humid summer heat can affect construction, outdoor work and training. Korean occupational-safety material uses WBGT-based heat-stress information, while official public warnings may use a separate apparent-temperature measure.
Forecasts describe outdoor conditions, not an individual's medical risk. Workload, duration, shade, clothing, acclimatization and health can change the appropriate decision.
