The U.S. just experienced its hottest 12 months on record
"In March the average temperature in the contiguous U.S. was about 50.9 degrees Fahrenheit (10.5 degrees Celsius) 9.35 degrees F higher than the 20th-century average for the month. It marks the first time any month's average has been nine degrees F higher than the 20th-century baseline, NOAA said in a statement. The warmer temperatures were particularly pronounced during the daytime, coming in at 11.4 degrees F higher than the last century's average."
"The average of these maximum daytime temperatures was so warm that it not only exceeded the average temperature for that month but was almost a degree F warmer than the 20th-century average for April a month that tends to be hotter as well. Ten U.S. states, including Arizona, California, Colorado, Idaho, Nevada and Texas, had their warmest recorded March."
"Alaska was the sole outlier state, with an average temperature of 0.6 degree F, making it the fourth coldest March there since Alaska's records began in 1925. And in March the World Meteorological Organization found that the period from 2015 to 2025 represented the 11 hottest years on record globally."
March in the contiguous U.S. averaged 50.9°F (10.5°C), which was 9.35°F higher than the 20th-century average for the month. The month marked the first time any monthly average exceeded the 20th-century baseline by nine degrees Fahrenheit. Daytime temperatures were especially elevated, averaging 11.4°F above the last century’s norm. The average maximum daytime temperature was nearly 1°F warmer than the 20th-century average for April. Ten states recorded their warmest March on record, including Arizona, California, Colorado, Idaho, Nevada, and Texas. Alaska was the exception, with an average temperature 0.6°F, making it the fourth coldest March since 1925. Globally, 2015–2025 included the 11 hottest years on record.
