Daily Temperature and Precipitation Reports - Data Tables

Daily Summary Observations

Daily summaries answer questions such as

  • What were the high and low temperatures at a station on a specific day?
  • How much did it rain last Wednesday?
  • How much snow was on the ground on a recent date? 

Where do these data come from?

Daily weather records come from automated and human-facilitated observation stations in the Global Historical Climatology Network-Daily database. Data from each station are reviewed regularly for quality and consistency: the data have been checked for obvious inaccuracies, but they have not been adjusted to account for the influences of historical changes in instrumentation or observing practices.

What can I do with these data?

  • Find daily records of high and low temperature and precipitation for most localities in the United States.
  • Display different variables to look for patterns and compare them among different dates.
  • Answer questions such as:
    • Where did it rain or snow on a specific date?
    • How does temperature change with latitude?
    • How much snow was on the ground at a station on a specific date?
  • How do I use the site?
