PROBLEM TO BE SOLVED: To provide a fog generation determining device, a fog generating area monitoring device, and a fog control device for monitoring a fog generating area and regulating the fog generating area within a preset range with a simple constitution.SOLUTION: The fog generation determining device includes a first thermometer arranged in vicinity of a cooling source having a lower temperature than the ambient air, a second thermometer arranged at a point substantially not receiving an influence of the cooling source, a hydrometer, thermometers arranged at respective points in a measuring point group including one or more measuring points, calculation means for determining a fog generation state by using measurement values of the first thermometer, the second thermometer, the hydrometer, and the thermometers arranged at respective points in a measuring point group, and means for outputting the calculation result. The fog generating area monitoring device determines the fog generating area based on the calculation result, and displays it. The fog control device controls the magnitude or/and shape of the fog generating area by controlling the temperature of an area in vicinity to the cooling source through change of a load of the cooling source according to the fog generating area.
