Has the climate in Tusayan changed?
Tusayan has warmed about 1.7°F since 1997.
About 0.6°F per decade, measured from Tusayan's official daily weather records, 1997–2025. Individual years still bounce around — some recent ones came in cool — but the long-term line has clearly risen.
What has actually changed
Each card compares the 1970s (the first ten years of the record) with recent years (the last ten) — the same span the headline and the chart use.
Tusayan's temperature, year by year
Average temperature for each year from 1997 to 2025.
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 19 more freezing nights a year and about 4 more days above 90°F compared with the 1970s.
Methodology & sources
Temperature — 1991–2020 normals computed from 24 years of daily observations at Grand Canyon NP AP, a weather station, about 4 km from the city centre. The underlying daily records come from NOAA's global station network.
