Regional Warmest/Wettest Year

« National Climate Report - Annual 2019


Regional Warmest/Wettest Year


Precipitation averaged across the contiguous United States (CONUS) during 2019 was the second wettest in the 125-year record. Despite the near-record wetness across the CONUS, only 5.8 percent of the total CONUS area experienced a record wet annual period. It is also interesting to note that some of the same regions experienced back to back record wet annual periods. These regions that were record wet in 2018 and 2019 are spatially in tune with the recent annual precipitation trends. Places have unique climate histories, including the local and regional "wettest years on record".

The first map below shows the local wettest year on record across the CONUS, considering total precipitation. The five largest footprints, which aren't necessarily the five wettest years overall, are depicted in unique colors; all other Years are combined into an "other" category. The other maps depict the same type of analysis, for: average temperature, minimum ("overnight low") temperature and maximum ("afternoon high") temperature.
