Seoul experienced its second consecutive "super tropical" night as the mercury again shot over 30 degree Celsius through the early hours of Friday morning. 

Super tropical nights are when temperatures exceed 30 degrees Celsius from 6 p.m. through 9 a.m. the following morning.

The Korea Meteorological Administration said morning lows in Seoul on Friday were 30-point-four degrees, the highest figure to be posted since the capital began weather observation in 1907. Temperatures broke a record high posted only the day before. 

Seoul has been seeing tropical nights for 13 days now. Such sweltering nights have continued for 17 days in Busan, 16 in Yeosu, and 14 in Gwangju and Daejeon. 

As of Friday afternoon, Yeongcheon, North Gyeongsang Province saw the highest afternoon temperature at 40 degrees Celsius. Capital Seoul also saw its afternoon high peaking at 37-point-nine degrees.
