"I requested somebody from Magical Maintenance to sort out my office, Cattermole. It’s still raining in there."
Corban Yaxley to Ron Weasley (disguised as Reginald Cattermole)[src]

The Atmospheric Charm (incantation unknown) was a type of Weather-Modifying Charm, which was used to create certain weather condition indoors. It could be removed with Meteolojinx Recanto.[1]



The famous Magizoologist Newton Scamander was known to have cast various highly intricate and powerful atmospheric charms in his magically expanded suitcase, which he used to house his various magical creatures, to create weather conditions suitable to the habitats of individual creatures, in order to adequately house them.[2]

The Wizbiz segment of The New York Ghost Sunday edition published on 28 November 1926 had an article regarding to how shopping experiences were affected by the atmospheric charm.[3]


During the 1990–1991 school year, the enchanted windows at the British Ministry of Magic Headquarters were bewitched with this charm using Reginald Cattermole's wand, possibly by an unidentified Metamorphmagus, causing them to display a hurricane. Professor Filius Flitwick identified this charm from the wand.[4]

Second Wizarding War

Ron Weasley: "I'll go and sort out Yaxley's office – but how do I stop it raining?"
Hermione Granger: "Try Finite Incantatem, that should stop the rain if it's a hex or curse; if it doesn't, something's gone wrong with an Atmospheric Charm, which will be more difficult to fix, so as an interim measure try Impervius to protect his belongings –"
Hermione Granger and Ron Weasley discussing how to fix broken Atmospheric Charms[src]

During the height of the Second Wizarding War, when Lord Voldemort was in control of the British Ministry of Magic, several Atmospheric Charms in the Ministry malfunctioned causing rain in offices.[1]

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 fix the malfunctioning charm.[1]

Behind the scenes

  • 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.
  • This charm is identified as the "Atmosphere Charm" in Harry Potter: Magic Awakened. On the spell card, Cassandra Vole casts the charm to create a local thunderstorm, but if the player taps the scene, Cassandra will say "Meteolojinx Recanto", which is in fact the incantation of a spell that removes the effect of the Atmospheric Charm.
