Find the dates and values for record-setting conditions at weather stations. Find data for records such as the highest and lowest temperatures, the most rain or snow, and the number of days below or above selected temperatures within the period of record.

Where do these data come from?

Measurements are collected by the U.S. Cooperative Observer Network (COOP), which typically has about 8,000 stations operating in any one year. Monthly extremes are extracted from the U.S. COOP Summary of the Month dataset (DSI-3220).
