County Extremes

County level data can provide a more localized picture of weather and climate conditions. Previously, the smallest aggregated scale of nClimGrid consisted of nClimDiv, which is the climate division dataset, consisting of 344 specified divisions across the contiguous United States. Counties are typically smaller than divisions, which makes them ideal for smaller-scale analyses. Currently, there are more than 3,100 counties or county-equivalents across the contiguous United States.

County-level data can provide specific information that is useful for drought managers, university researchers, agriculture producers, and business leaders. Below are the counties that experienced the most extreme average temperature and total precipitation values in October, August-October and January-October. Each color represents a historical county rank for the time period. Shades of blue or red represent counties whose temperature values were cooler or warmer than their historical average. Shades of brown or green represent counties whose precipitation values were drier or wetter that their historical average. For more information on ranks, please see Climatological Rankings.
