August 18th – August 22nd, 2025 is Autumn – End of RISSHU (Start of autumn)-39th KOU “Thick fog descends.”
According to the 24 SEKKI (Major divisions), it’s RISSHU (Start of autumn) and the SHICHIJYUNI-KOU tells that thick fog descends.
Cloud fog and radiation fog are likely to occur, especially in basins surrounded by high mountains. NAGANO City (ZENKOJI-DAIRA BONCHI) where I live is such a place.
The heat has been still intense even after the end of OBON, but the mornings and evenings have become a little comfortable. If I sleep with the windows fully open, sometimes I may find myself needing a thin blanket at dawn.
