Based on the daily meteorological data in Fuzhou from 1961 to 2012, the monthly human comfortability is analyzed with the torridity index. The results show that: (1) The human comfort index based on daily mean temperature can reflect human sensation in all seasons except summer; however, the human comfort index from maximum temperature can reflect human’s real feeling. (2) The comfort degree can be divided into 5 levels: January to February (cold); March, November, and December (slightly cold); April to June and September (comfort); July to August (a little hot); October (fairly comfort). May is most comfort, January is most cold, and July is the hottest. (3) The comfort index increased obviously during the last 50 years. Although the increase trend of comfort index was not significant, the large values appeared after the late 1990’s. The results indicate that the human comfort degree increased in winter, especially after the late 1980’s.
