'''불쾌지수'''({{llang|en|Temperature Humidity Index, THI}})는 열과 [[습도]]의 영향을 결합하는 지수를 말한다. 불쾌지수는 [[이슬점]]을 기반으로 한 [[무차원 수]]이다.

== 역사 ==
불쾌지수를 결정하기 위한 현재의 공식은 1979년에 캐나다 대기 환경 서비스의 J.M. 마스터튼과 F.A. 리처드슨이 개발했다. 불쾌지수는 미국에서 사용된 [[열지수]]와 [[상대 습도]]보다는 [[이슬점]]에서 파생된 점이 다르다.

오랫동안 캐나다의 불쾌지수 기록은 캐나다 환경청에 보고된대로, 1953년 6월 20일에 52.1일을 기록한 온타리오 주 윈저에서 결정되었다.
