Dover through time

Dover weather since 1893

NOAA has kept daily weather records in Dover since 1893. Here are the records and the average for each year, with the gaps and station moves noted.

All-time records

Readings from the last 12 months are recent and NOAA may still correct them.

Average temperature by year, Dover station

Years with more than 5 missing days in any month show no average.

Gaps and station moves

Dover, DE (cooperative station) (USC00072730)

Daily records start in January 1893. NOAA has no daily data for 1897, 1899 to 1905, and from June 1916 to July 1919, and only part of 1894, 1906, 2009, 2020 and 2021.
The station has moved. NOAA lists it 0.2 miles southeast of the Dover post office from 1919 to 1948, at a nearby site from 1948 to 1969, about 7 miles north of downtown from 1969 to 1995, and at the state highway department on Route 113 since 1995.
A move can change readings by a degree or more, so small differences between decades are not proof of a trend.

Dover Air Force Base (USW00013707)

NOAA GHCN-Daily has Dover Air Force Base readings for July 1946, part of 1949 and 1950, 1951 to 1970, and again from 2025. The years 1971 to 2024 are not in this dataset.
