An atmospheric pressure tendency informing apparatus and atmospheric pressure tendency informing method inform atmospheric pressure tendency. In one implementation, the atmospheric pressure tendency informing apparatus includes: an informing section, an atmospheric pressure measuring section, an atmospheric pressure inflection point judging section and an informing control section. The atmospheric pressure inflection point judging section judges whether there is an inflection point of atmospheric pressure, based on atmospheric pressure values of at least three points of time including an atmospheric pressure value measured at present. The informing control section controls the informing section to inform the inflection point of atmospheric pressure as the atmospheric pressure tendency based on a judgment result when the atmospheric pressure inflection point judging section judges there is an inflection point of atmospheric pressure.
