Historical heat index data
These daily mean, minimum, and maximum heat index products are guidance products. Official forecasts of instantaneous apparent temperatures (e.g., heat index or wind chill) are displayed on the National Weather Service web page. Definition of Heat Index: The heat index is an estimate of how hot the air “feels” to the human body and provides a relative indication of potential health risks. Among others, the two primary factors in the heat index equations are temperature and water vapor (i.e., moisture/humidity). Reported measures are the average temperature, number of observations, and range for the daily maximum and minimum air temperatures, and also percent coverage for the daily maximum heat index. Data are available by place (combined 48 contiguous states, region, division, state, county), time (year, month, day) and specified maximum and minimum air temperature, and heat index value. Reported measures are the average temperature, number of observations, and range for the daily maximum and minimum air temperatures, and also percent coverage for the daily maximum heat index. Data are available by place (combined 48 contiguous states, region, division, state, county), time (year, month, day) and specified maximum and minimum air temperature, and heat index value.

The page that follows will feature numerous categories and links. Climate data may be arranged on a daily, monthly and annual basis. Click the links and use any pull-down menus to navigate to the information you desire. Month-to-date data likely will appear on this climate page and is among the most popular. Climate data, including past weather conditions and long-term averages, for specific observing stations around the United States is only a few clicks away. Certified weather data for use in litigation is available only through the National Climatic Data Center in Asheville, N.C.

Air Dwpt This figure shows the annual values of the U.S. Heat Wave Index from 1895 to 2015. These data cover the contiguous 48 states. Interpretation: An index value of 0.2 (for example) could mean that 20 percent of the country experienced one heat wave, 10 percent of the country experienced two heat waves, or some other combination of frequency and area resulted in this value.
Oct 11, 2018 The heat index, also known as the “feels-like” temperature, shows how hot it feels and Chicago are calculated using weather station data between 1981 and 2005, and do not match model-estimated historical heat indexes.
