Regional Warmest/Wettest Year


Year 2016 was the second warmest of the 122 on record, when temperatures are averaged across the contiguous United States (CONUS). The breadth of the 2016 warmth is unparalleled in the nation's climate history. No other year had as many states breaking or close to breaking their warmest annual average temperature. Despite the expansive warmth across the CONUS, only 3.7 percent of the total CONUS area experienced a record warm annual period. Places have unique climate histories, including the local and regional "warmest Years on record".

The first map below shows the local warmest Year on record across the CONUS, considering average temperature. The five largest footprints, which aren't necessarily the five warmest 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: minimum ("overnight low") temperature, maximum ("afternoon high") temperature and total precipitation.
