"List the record temperatures for each state in the United States."
All 50 of 50 U.S. states are covered, each with its official all-time maximum and minimum measured air temperature in °F, the date and recording location of each, and the high-to-low span. The official values are single-sourced from the NOAA/NCEI State Climate Extremes Committee, checked 2026-09-08, with independent secondary pages used for verification.
Warm colours = hotter record; cool colours = colder record. Hover a state for both records, dates and places.
Eight states' records disagree between NOAA and secondary compilations — Hawaii's low (12 vs 15 °F), Idaho's high (118 vs 119 °F), plus Kentucky, South Carolina, South Dakota, Utah, Vermont and Wyoming. ncei.noaa.gov
