Arizona climate calendars

Climate calendars are tools that provide a summary of records for an individual weather station, often based on the Calendar Year.

The Arizona climate calendars provide climate normals, means, and extremes for many active weather stations across the state. Climate normals are calculations based on 30-year monthly averages (means), often for maximum (high) and minimum (low) temperatures and total monthly precipitation.

Climate extremes are based on the period of record. The period of record is the extent of the time that the weather station has been in operation. For example, precipitation records for Yuma go back to 1876 and temperature records for Yuma go back to 1878. An extreme would be the highest, lowest, or greatest observation during the period of record.

The current 30-year climatological standard for climate normals runs from January 1, 1991 to December 31, 2020.

These records are based on the Calendar Year (January to December). Click on the location to access the climate calendar for that weather station.
