Calculate, compare and share
Understanding the answer
The National Weather Service records an estimated 7°F at noon in 1985 and 27°F at noon for the 2025 presidential inauguration. Both ceremonies moved indoors because of the cold. Temperatures are historical observations, not live readings.

The decisive measurement
The National Weather Service lists a noon temperature of 7°F for the 1985 Reagan inauguration and 27°F in 2025. The measured gap is 20°F. Compare noon temperatures rather than daily lows, because mixing those measures produces a false ranking.
Why Reagan’s 1985 public ceremony moved indoors
The inauguration fell on a Sunday in 1985, with the public observance the next day. Record cold and severe wind chill shifted the public ceremony to the Capitol Rotunda.
The 2025 indoor ceremony
The 2025 ceremony also moved to the Capitol Rotunda. The National Weather Service describes 27°F around noon and a wind chill near 14°F, cold but above the 1985 noon record.
Limits of inauguration weather rankings
A historical top-ten chart should only use comparable, sourced observations. Where records use different times, sites or measurement conventions, the page should disclose that instead of inventing a ranked list.

Why 1985 Still Matters in Every Modern Comparison
When comparing a Coldest Inauguration Days in History: 1985 vs 2025 count with another year, use the same inclusive/exclusive rule and timezone for both intervals. An extra February 29 can alter the elapsed-day total, and ISO week numbering may cross January 1. Record the inputs with your calculation so another reader can reproduce it.

How to calculate and verify the result
To verify the count for Coldest Inauguration Days in History: 1985 vs 2025, write the start as 1985-01-20 and select a second complete date in ISO year-month-day format. Subtract the two civil dates, counting February 29 wherever it lies within the interval; then decide whether to include the starting date. For example, day 1 after January 20, 1985 is January 21, 1985. A Monday–Friday result differs because it removes weekends but not public holidays.

Sources and verification
Sources for Coldest Inauguration Days in History: 1985 vs 2025 appear beside the relevant historical, scientific or medical statement.

The calculator result itself follows published Gregorian calendar rules; source links are not endorsements by the named organizations.
Why the 1985 ceremony was an exceptional weather event
January 20, 1985 was a Sunday. Ronald Reagan took the constitutionally required oath privately that day, while the public ceremony was scheduled for Monday, January 21. With a noon outdoor temperature of 7°F on January 21, organizers moved the public proceedings inside the Capitol Rotunda and canceled the outdoor parade. A comparison table must identify which ceremony and date each temperature describes.
Reported temperature versus wind chill
The National Weather Service reports a January 1985 afternoon wind chill between −10°F and −20°F. Wind chill estimates the effect of moving air on exposed skin; it is not a second reading from a thermometer. Compare actual noon air temperatures with actual noon air temperatures, not a 1985 wind-chill figure with the 2025 air reading.
January 2025: another indoor inauguration
The 2025 public inauguration was moved into the U.S. Capitol Rotunda before the event because of forecast cold and wind. The National Weather Service records 27°F at noon, with a wind chill of 14°F. These official measurements make it 20°F warmer than 1985 on the comparable noon-temperature measure.
How to verify a historical inauguration comparison
Start with the National Weather Service table of inauguration weather rather than headlines mixing forecasts, overnight lows and wind chill. Check the Joint Congressional Committee account to establish the ceremony location and its actual date. For January 1985, keep the private Sunday swearing-in separate from the public Monday ceremony. When a journalist discusses “the coldest inauguration,” the definition and recorded time should be explicit.
