{"chart":{"slug":"us-temperature-last-12-months","title":"How have the last 12 months compared with normal in the US?","takeaway":"Of the 12 months from October 2025 to September 2026, March 2026 was the warmest compared with normal across the contiguous US, 9.4°F above its 1901–2000 average for that month. May 2026 was the coolest compared with normal, at 1.5°F (below zero means colder than average). Each bar compares a month with the same month's average, so a warm January and a warm July are measured alike.","topic":"Climate","chart_type":"bar","ranking":false,"x_label":"Month","y_label":"°F above (or below) that month's 1901–2000 average","unit":null,"points_count":12,"source":{"name":"NOAA National Centers for Environmental Information, Climate at a Glance","url":"https://www.ncei.noaa.gov/access/monitoring/climate-at-a-glance/national/time-series"},"license":{"name":"Public domain (U.S. government work)","url":"https://www.usa.gov/government-copyright"},"data_as_of":"2026-09-30","updated_at":"2026-10-17T18:50:41.767Z","url":"https://chart.ly/charts/us-temperature-last-12-months","api_url":"https://chart.ly/api/v1/charts/us-temperature-last-12-months","csv_url":"https://chart.ly/charts/us-temperature-last-12-months/data.csv","image_url":"https://chart.ly/charts/us-temperature-last-12-months/image.png","embed_url":"https://chart.ly/charts/us-temperature-last-12-months/embed","credit":"NOAA National Centers for Environmental Information, Climate at a Glance, via Chartly (https://chart.ly/charts/us-temperature-last-12-months)","credit_html":"NOAA National Centers for Environmental Information, Climate at a Glance, via \u003ca href=\"https://chart.ly/charts/us-temperature-last-12-months\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"Oct 2025","value":2.85},{"label":"Nov 2025","value":5.0},{"label":"Dec 2025","value":5.15},{"label":"Jan 2026","value":3.0},{"label":"Feb 2026","value":6.44},{"label":"Mar 2026","value":9.35},{"label":"Apr 2026","value":3.73},{"label":"May 2026","value":1.49},{"label":"Jun 2026","value":2.19},{"label":"Jul 2026","value":3.32},{"label":"Aug 2026","value":3.46},{"label":"Sep 2026","value":4.58}],"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/us-temperature-last-12-months)"}
