{"chart":{"slug":"rainfall-change-by-state","title":"Which US states are getting wetter or drier?","takeaway":"In the 10 years through 2025, yearly rain and melted snow compared with the 1901–2000 average ranged from 14.7% in Kentucky and 13.7% in Michigan to -12.8% in Arizona; across the contiguous US it changed by 4.5%. Ten years is short for rainfall, so a few very wet or dry years move a state a lot. Hawaii's records start in 1991, so it isn't included.","topic":"Climate","chart_type":"bar","ranking":true,"x_label":"State","y_label":"Percent change in yearly precipitation, last 10 years vs. the 1901–2000 average","unit":"percent","points_count":50,"source":{"name":"NOAA National Centers for Environmental Information, Climate at a Glance","url":"https://www.ncei.noaa.gov/access/monitoring/climate-at-a-glance/statewide/time-series"},"license":{"name":"Public domain (U.S. government work)","url":"https://www.usa.gov/government-copyright"},"data_as_of":"2025-12-31","updated_at":"2026-10-17T18:50:41.573Z","url":"https://chart.ly/charts/rainfall-change-by-state","api_url":"https://chart.ly/api/v1/charts/rainfall-change-by-state","csv_url":"https://chart.ly/charts/rainfall-change-by-state/data.csv","image_url":"https://chart.ly/charts/rainfall-change-by-state/image.png","embed_url":"https://chart.ly/charts/rainfall-change-by-state/embed","credit":"NOAA National Centers for Environmental Information, Climate at a Glance, via Chartly (https://chart.ly/charts/rainfall-change-by-state)","credit_html":"NOAA National Centers for Environmental Information, Climate at a Glance, via \u003ca href=\"https://chart.ly/charts/rainfall-change-by-state\"\u003eChartly\u003c/a\u003e","average_label":"Contiguous U.S.","zero_axis":true,"data":[{"label":"Kentucky","value":14.7},{"label":"Michigan","value":13.7},{"label":"Wisconsin","value":13.6},{"label":"Rhode Island","value":13.1},{"label":"Arkansas","value":11.9},{"label":"Tennessee","value":10.8},{"label":"Virginia","value":10.5},{"label":"Pennsylvania","value":10.3},{"label":"South Dakota","value":10.0},{"label":"New York","value":9.8},{"label":"Ohio","value":9.6},{"label":"Oklahoma","value":9.6},{"label":"Indiana","value":9.3},{"label":"Massachusetts","value":9.0},{"label":"Minnesota","value":8.8},{"label":"Louisiana","value":8.4},{"label":"Mississippi","value":8.0},{"label":"Vermont","value":8.0},{"label":"New Hampshire","value":7.5},{"label":"Illinois","value":7.3},{"label":"West Virginia","value":7.2},{"label":"Maine","value":7.1},{"label":"Iowa","value":6.6},{"label":"North Carolina","value":6.5},{"label":"Alaska","value":6.1},{"label":"Nebraska","value":5.7},{"label":"New Jersey","value":5.5},{"label":"Alabama","value":5.2},{"label":"Missouri","value":5.2},{"label":"Kansas","value":5.1},{"label":"Connecticut","value":4.7},{"label":"Contiguous U.S.","value":4.5},{"label":"Maryland","value":4.4},{"label":"Delaware","value":4.1},{"label":"North Dakota","value":3.9},{"label":"South Carolina","value":3.7},{"label":"Georgia","value":2.9},{"label":"Texas","value":2.9},{"label":"Florida","value":2.2},{"label":"Washington","value":0.4},{"label":"Wyoming","value":0.2},{"label":"California","value":-0.4},{"label":"Montana","value":-0.8},{"label":"Nevada","value":-1.9},{"label":"Idaho","value":-2.9},{"label":"Oregon","value":-4.5},{"label":"Colorado","value":-6.2},{"label":"Utah","value":-7.3},{"label":"New Mexico","value":-10.9},{"label":"Arizona","value":-12.8}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"NOAA National Centers for Environmental Information, Climate at a Glance, via Chartly (https://chart.ly/charts/rainfall-change-by-state)"}
