According to the sources, freezing temperatures in Phasmophobia are temperatures strictly below 0°C/32°F. If the thermometer reads 0°C or below, it is considered evidence of a ghost that causes freezing temperatures. However, there is an error margin of 2°C on the thermometer, which could cause incorrect readings, especially when a ghost doesnt use freezing temperatures as evidence. In Clear Skies weather, a temperature of 3°C or lower is also considered evidence of a ghostly presence. It is important to note that not all ghosts cause freezing temperatures, and only certain ghosts will cause the temperature to drop to freezing. The following ghosts can be found in freezing temperatures: Demon, Hantu, Jinn, Moroi, Oni, Onryo, Revenant, Shade, The Mimic, The Twins, and Yurei.
