Vermont Weather Records
The official all-time extremes for Vermont, as NOAA’s State Climate Extremes Committee lists them: from 107°F at Vernon to -50°F at Bloomfield.
Maximum Temperature
| Record | Date | Where | Station | Status |
|---|---|---|---|---|
| 107°F | July 7, 1912 | Vernon | 438600 | N: Value is changed from extremes tables last updated by NCEI (formerly NCDC) between 1998 and 2006. Value exceeds all other valid values. |

| Record | Date | Where | Station | Status |
|---|---|---|---|---|
| -50°F | December 30, 1933 | Bloomfield | 430690 | E: Value is unchanged from previous extremes tables last updated by NCEI (formerly NCDC) between 1998 and 2006. Value exceeds all other valid values. |
The -50 degrees F minimum temperature ties with values from NH and ME as the all-time coldest temperature for the Northeast region of the United States.
Greatest 24-Hour Precipitation
| Record | Date | Where | Station | Status |
|---|---|---|---|---|
| 9.92 inches | September 17, 1999 | Mt. Mansfield | 435416 | N: Value is changed from extremes tables last updated by NCEI (formerly NCDC) between 1998 and 2006. Value exceeds all other valid values. |
Maximum 24-Hour Snowfall
| Record | Date | Where | Station | Status |
|---|---|---|---|---|
| 42 inches | February 5, 1995 | Jay Peak | 434189 | N: Value is changed from extremes tables last updated by NCEI (formerly NCDC) between 1998 and 2006. Value exceeds all other valid values. |
Two potential 24-hour snowfall records of 44.8 inches at Peru (COOP ID: 436335) and 42.0 inches at Landgrove 1.1 NNE (CoCoRaHS ID: VT-BN-3) over a 24-hour period on 16-17 December 2020 were examined by the SCEC during the following year. The SCEC found that observational practices associated with the measurements reduced confidence in these values. The SCEC determined by two separate 5-0 votes that the existing Jay Peak record be upheld.

| Record | Date | Where | Station | Status |
|---|---|---|---|---|
| 149 inches | April 2, 1969 | Mt. Mansfield | 435416 | N: Value is changed from extremes tables last updated by NCEI (formerly NCDC) between 1998 and 2006. Value exceeds all other valid values. |
