© NOAA/NCEI.Annual precipitation across the contiguous U.S. has increased by about 7% over the past century. Blue bar shows the linear increase since 1895, while the red curve is a smoothed version of the year-to-year numbers in green. When averaged over running four-year periods (not shown), the past four years are the wettest on record for the contiguous U.S.
Given the fierce drought-related impacts of the 2010s—including multiple deadly wildfire disasters from Tennessee to California—it may seem a bit counterintuitive that the nation has actually been getting wetter overall. Across the contiguous U.S., average yearly precipitation has risen by about 2" over the past century, from around 29" to just over 31" (see Figure 1). For the entire nation, including Alaska and Hawaii, precipitation increased by about 4% in the period from 1901 to 2015, according to the U.S. National Assessment.
