General

Explore the number of weather records broken over recent periods. Compare counts of high maximum, high minimum, low maximum, and low minimum temperature records as well as records for precipitation, snowfall, and snow depth in the United States or across the globe. Be aware 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?

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.
