The Atmospheric Charm (incantation unknown) is a type of Weather-Modifying Charm. This charm can function indoors. It can be removed with Meteolojinx Recanto.


During the height of the Second Wizarding War, when Lord Voldemort was in control of the Ministry of Magic, several Atmospheric Charms in the Ministry malfunctioned causing rain in offices.

It caused these effects in Bletchley's office and in the office of the head of the Department of Magical Law Enforcement, Corban Yaxley. Bletchley successfully removed it himself, while Yaxley assigned Reginald Cattermole — who happened to be actually Ron Weasley in disguise — to repair the charm.

  • The fact that Atmospheric Charms are known to be used in office spaces (and can malfunction, requiring custodian intervention) might be a nod to real-world air-conditioning.
