Has Quantico been warmer than normal lately?

2023 averaged 60.1°F, 2.0°F above the 1991-2020 normal of 58.1°F. 3 of the 3 complete years since 2021 ran warmer than the normal.

How does Quantico's climate compare?

Quantico is warmer than 56 of the other 80 places with their own NOAA record in Virginia, and wetter than 6. Across the 7,247 U.S. stations with normals, its annual mean of 58.1°F is warmer than 69%.

In the Köppen classification computed from these normals, Quantico is Cfa: temperate, no dry season, hot summer. What the classes mean.

Which places near Quantico share this climate record?

16 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
