About 0.5°F per decade, measured from Montgomery's official daily weather records, 1971–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
Is that a lot? Montgomery's warming is broadly in line with other cities in United States — neither unusually fast nor unusually slow.

Montgomery's temperature, year by year
Average temperature for each year from 1971 to 2025.
a warmer-than-average year a cooler-than-average year
Each bar is one year. Most recent years sit above the older ones.
Some recent years still came in cool — warming is a slope,
not a straight climb.
In day-to-day terms, that long-term shift shows up as about 12 more days above 90°F compared with the 1970s.

Useful if you garden or care about a particular season —
otherwise the headline above already has the answer.
February has warmed the most — about 2.0°F. The warming runs across the whole year, not just one season.
