On Monday, freezing temperatures in Washington D.C. prompted organizers to move President Donald Trump’s inauguration ceremony inside the Capitol Rotunda for the first time since 1985.

Washington, D.C., will experience a high of 21 degrees and a low of 11 degrees around noon when the inauguration is set to begin.

It will be the coldest Inauguration Day since former President Ronald Reagan’s second inauguration in 1985, when the noon temperature was 7 degrees.

The worst weather for an inaugural came in March 1909, when 10 inches of snow forced William H. Taft to move indoors to be sworn in.

The second Presential inauguration of Donald Trump averaged 24.3 million viewers, a audience lower than Biden in 2021 (33.8 million) and Trump in 2017 (30.6 million).

Ironically, the coldest inauguration was just four years later, when President Ronald Reagan publicly took the oath for a second time. The morning started off at 4 below zero. By noon, it was just 7 degrees, and wind chills ranged from -10 to -20 degrees. Not only was the swearing-in held indoors, but the parade was also canceled.

President-elect Donald Trump selected opera tenor Christopher Macchio to perform the national anthem at the inauguration. Here's a list of some singers at previous presidential inaugurations.
