Has Mayo been warmer than normal lately?
Over 46 complete years from 1951 to 2025, the station's annual mean temperature rose at a fitted 1.3°F per century (+0.07°C per decade). A fitted rate summarizes the whole record; single years swing well above and below it.

Which places near Mayo share this climate record?
Day has no NOAA station with 1991-2020 normals of its 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.
