• Trump's swearing-in is set to move indoors to the Capitol Rotunda because of extreme cold.
• The temperature at noon is expected to reach around 22 degrees Fahrenheit with significant wind chill.
• This is the first indoor inauguration since 1985, during Ronald Reagan's second term.
• Alternate viewing arrangements are in place for the approximately 250,000 guests expected.
• Trump emphasized safety for his supporters amid the Arctic blast conditions.

Due to forecasts projecting extreme cold weather conditions, President-elect Donald Trump will take the oath of office from inside the Capitol Rotunda on Monday. “The weather forecast for Washington, D.C., with the windchill factor, could take temperatures into severe record lows,” Trump stated on his Truth Social platform. He added, “There is an Arctic blast sweeping the Country. I don’t want to see people hurt, or injured, in any way.”

The Rotunda, prepared as an alternative for inaugurations during inclement weather, has last hosted an indoor ceremony in 1985 for President Reagan’s second inauguration, which was marked by similarly low temperatures. The forecast for Monday anticipates temperatures plummeting to around 22 degrees Fahrenheit (approximately -6 degrees Celsius), marking the lowest temperatures for an inauguration day since that historic event, where it plunged to 7 degrees Fahrenheit (about -14 degrees Celsius).

While outgoing President Joe Biden, members of Congress, and other dignitaries will witness the ceremony inside the Capitol, alternate plans are being arranged for the estimated 250,000 guests ticketed for viewing around the grounds, plus tens of thousands more expected to line the inaugural parade route from the Capitol to the White House. Attendees will also have a chance to watch the event from Washington's Capital One Arena, which Trump plans to visit following the ceremony. His inaugural committee confirmed these arrangements, recognizing the brisk conditions expected on the day of the event.

The National Weather Service is warning that wind speeds could reach 48 to 56 km/h (30 to 35 mph), potentially driving wind chills into the single digits. Trump's inaugural events, planned for his supporters, will still take place as scheduled amidst these challenging weather conditions.
