The 2025 United States Presidential Inauguration is now more likely to be moved indoors due to the coldest weather for an inauguration in 40 years for Washington, D.C., with a high in the upper teens to low 20s.

T​his will be the first inauguration to be held indoors in 40 years. The record for the coldest January inauguration is currently held by the second inauguration of Ronald Reagan in 1985, when the temperature at noon for the swearing-in ceremony was only 7 degrees, according to the National Weather Service.

The weather for this year’s inauguration is forecast to somewhat mimic that of 1985, which took place on Jan. 21. The high temperature that day was 17 degrees, with sunny skies and afternoon wind chills in the minus 10 to minus 20-degree range. The parade was ultimately canceled, and the swearing-in ceremony had to be held indoors.

The Rotunda is prepared as the inclement weather alternative for each inauguration in the event of inclement weather, according to the Associated Press.

The 2025 Inauguration will be similarly sunny, with wind chills in the lower teens or single digits and winds gusting up to 35 mph in the afternoon. During the ceremony, the temperature will hover in the lower 20s.

Alternate plans are required for the more roughly 250,000 guests ticketed to view the inauguration from around the Capitol grounds and the tens of thousands more expected to be in general admission areas or to line the inaugural parade route from the Capitol to the White House.

Trump said some supporters would be able to watch the ceremony from Washington’s Capital One area on Monday, a day after he plans to hold a rally there. He said he would visit the arena after his swearing-in.

The current forecast high for Inauguration Day is only a couple of degrees above the current record for coldest afternoon high on Jan. 20, though it would break the record for the coldest Inauguration to take place on that date.

Only one other year had a sub-freezing high on inauguration day: Barack Obama’s first inauguration in 2009.

The warmest January Inauguration Day took place in 1981 for Ronald Reagan’s first inauguration, meaning Reagan’s two inaugurations hold the record for the warmest and coldest January Inauguration.

Warmer inaugurations have happened though: Before the 20th Amendment was enacted, Inauguration Day traditionally took place on March 4, which has an average high of 50.2 degrees. Jan. 20 has a cooler average high of 42.9 degrees.

The all-time record high for a U.S. presidential inauguration was set in August 1974 with the Inauguration of Gerald Ford with a high of 83 degrees, though that was a non-traditional inauguration date prompted by the resignation of Richard Nixon.

Here’s a look at some other notable inauguration day weather.

Snowiest Inauguration: William Taft, 1909

Fun fact: Historically speaking, there is approximately a 30% chance of snow on the ground in Washington, D.C., from a previous system for the date Jan. 20.

Worst Inauguration Day Travel: JFK, 1961

On the eve of John F. Kennedy’s inauguration in 1961, 8 inches of snow fell causing the most crippling traffic jam of its time. Hundreds of cars were stranded and abandoned. The president-elect had to cancel dinner plans and, in a struggle to keep other commitments, is reported to have had only 4 hours of sleep. Former President Herbert Hoover was unable to fly into Washington National Airport because of the weather and missed the swearing-in ceremony. By sunrise, the snowfall had ended and the skies cleared but the day remained bitterly cold.

An army of men worked all night to clear Pennsylvania Avenue, and despite the cold, a large crowd turned out for the swearing-in ceremony and inaugural parade. At noon, the temperature was only 22 degrees with the wind blowing from the northwest at 19 mph making it feel like the temperature was just 7 degrees.

Fatal Inaugurations: William Henry Harrison, 1841, and Franklin Pierce, 1853

The weather has caused two inaugurations to have fatal implications, and the most historically significant fatality was that of William Henry Harrison in 1841. Harrison decided to brave the elements and deliver the longest inauguration speech ever, an oration lasting an hour, and 40 minutes.

It was a cloudy, cold and blustery day, and the National Weather Service has estimated the temperature at noon to be approximately 48 degrees.

Harrison, who wore neither hat nor overcoat, also rode a horse to and from the Capitol ceremony. He subsequently caught a cold that developed into pneumonia. Harrison died a month later.

The second inauguration with a fatal effect was that of Franklin Pierce in 1853. The morning of the inauguration, there was heavy snow that continued until about half an hour before the ceremony. Skies looked to be brightening by noon, but the snow resumed shortly after Pierce took the oath of office.

The heavy snow dispersed much of the crowd and ruined plans for the parade. Abigail Fillmore, first lady to the outgoing President Millard Fillmore, sat on the cold, wet, exposed platform during Pierce’s swearing-in ceremony. She caught a cold that developed into pneumonia and died at the end of the month.

Rainiest Inauguration: Franklin D. Roosevelt, 1937

The first inauguration to be held on Jan. 20 – Franklin D. Roosevelt’s second inauguration in 1937 – also set the record for the heaviest rain on inauguration day. The day was cold and rainy, with sleet and freezing rain in the morning. Between 11 a.m. and 1 p.m., a period that includes the swearing-in ceremony, nearly three-quarters of an inch of rain fell.

Roosevelt insisted on riding back to the White House in an open car with half an inch of water on the floor. Total rainfall for the day was 1.77 inches, which remains the rainfall record for Jan. 20.

First Outdoor Oath: James Monroe, 1817

The first seven inauguration ceremonies from 1789 to 1813 were conducted indoors, making James Monroe’s 1817 inauguration the first that was held outdoors in the weather. Luckily, it was warm and sunny that day, with an estimated temperature at noon of 50 degrees.
