Observed Number of Very Warm Nights
Figure 44.3North Carolina State University
Kenneth E. Kunkel
The observed number of very warm nights (annual number of days with minimum temperature at or above 75°F) for 1900–2018, averaged over 5-year periods (bars; last bar represents 4-year average). Filled circles connected by black line segments show annual values. The horizontal black line shows the long-term average for 1900–2018 is 1.6 nights per year. These values are averages from 12 long-term reporting stations. While high nighttime temperatures are historically rare for Utah due to its semiarid climate and high average elevation, the frequency of very warm nights has risen dramatically over the past three decades. During the 2000–2004 period, the number of such nights was more than double the long-term average. Source: CICS-NC and NOAA NCEI.
