Record-setting weather - Charts and Maps

Climate Data Online > Data Tools > Daily Weather Records

Explore the number of weather records broken over recent periods. Compare counts of temperature and precipitation records in the United States or across the globe.

Please note that these counts can provide insight into recent climate behavior, but they do not offer a definitive way to identify trends in the number of records set over time.

Where do these data come from?

The Daily Weather Records data tool is hosted and maintained by NOAA NCEI as part of Climate Data Online. Broken and tied records counted or displayed by this tool are compiled from a subset of stations in the Global Historical Climatological Network. For a station to be counted as having broken or tied a record, it must have a minimum of 30 years of observations for that variable, with more than 182 days complete during each of the 30 years. If you have further questions or comments about the Daily Weather Records tool, you can reach out to NCEI through this email address.

  • How do I use the site?

    Go to the Daily Weather Records page at NOAA NCEI.

    On the View Records Summary tab, select U.S. Summaries or Global Summaries, and then scroll down to view the charts.

    On the  View Selected Records tab, use the drop-down menus to select a timescale, location, and date range, and parameters of your search.

    • Click "Show Records" 
    • If records were broken (or tied) at valid station within the selected date range, the map will show locations where the record was set. A table describing the broken (or tied) records will appear below the map.

    What can I do with these data?

    • Click the View Records Summary tab to compare counts of broken or tied records in the United States and around the world. 
    • Compare the ratios of different types of temperature records (High Max vs. Low Min, for example) to look for trends. Which types of records are most dominant during the period you checked?
    • Click the View Selected Records tab to identify record-setting events on a map and in a table. Compare recording-setting values to their previous values.
