This figure appears in chapter 18 of the NOAA-led State Summaries 2019 report.

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. These values are averages from 13 long-term reporting stations. Louisiana has experienced a substantial increase in the frequency of very warm nights over the past two decades. During the most recent 9-year period (2010-2018), the number of such nights has been double the long-term average. The dark horizontal line is the long-term average of 18 days per year.
