National Climate Report - Annual 2018
Regional Warmest/Wettest Year

« National Climate Report - Annual 2018


Regional Warmest/Wettest Year


Precipitation averaged across the contiguous United States (CONUS) during 2018 was the third wettest in the 124-year record. Despite the expansive wetness across the CONUS, only 6.4 percent of the total CONUS area experienced a record wet annual period. 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.
