Methods and systems for humidity monitoring and adjustment are described herein. Data from at least one external sensor system is received by a computing device. The external sensor system determines at least one of outdoor air temperature and outdoor air humidity. Data from at least one internal sensor system is received by the computing device. The internal sensor system determines at least one of indoor air temperature and indoor air humidity. A dew point for an indoor environment is calculated based upon the data from the external sensor system and data from the internal sensor system. A graphical indication of an indoor environment climate may be displayed based upon the calculated dew point. Access openings, such as windows, may be opened or closed to change the humidity of the indoor environment.
