About this site
Shade Trove is a plain republication of one part of the U.S. Climate Normals 1991-2020 published by NOAA's National Centers for Environmental Information (NCEI). It is a static site: there are no accounts, no forms and no tracking scripts.
What the figures are
For each U.S. weather station that carries a temperature normal, the site shows the normal daily maximum temperature for June, July and August and the normal number of days at or above 90 F, read as-is from NCEI's monthly multivariate file. The period the figures cover is the 1991-2020 normal period as NCEI defines it. A cell with no value in the source is printed as “not available”; nothing is estimated, averaged or filled in.
Values are copied from the source records without recalculation. A number may appear with a thousands separator or with trailing decimals shortened; that is formatting only.
