A temperature of 64-70°F (18-21°C) is considered ideal. At lower temperatures,  below 54°F (12°C), the desired aging process of the cigars is impaired.  Therefore, cold wine cellars are only suitable for cigar storage to a limited  extent. Even worse are high temperatures. Temperatures of over 75°F (24°C)  can lead to worm infestation and cigar rotting. For this reason, the humidor should  not be exposed to direct sunlight.
