What this measure is
The average number of days a year with a high of 95°F or more, over 2015–2024. Each place is the average of the 4-kilometre grid cells where its residents live, so it describes the heat people experience rather than the hottest corner of the area. It does not account for humidity. Hatched areas have no figure: the source covers only the lower 48 states, not Alaska or Hawaii.
