  1. ^ Mean monthly maxima and minima (i.e. the expected highest and lowest temperature readings at any point during the year or given month) calculated based on data at said location from 1991 to 2020.
  2. ^ Official records for Little Rock began on 1 July 1879 at the State Capitol and maintained there until 30 April 1942. The next day, and until 7 August 1942, temperature and precipitation were recorded separately at two different locations in and around Little Rock, and the official climatology station has been Adams Field since 8 August 1942.
