U.S. Climate Extremes, Significant Events November, Fall 2015
November, saw 4,502 record warm daily high (1,642) and low (2,860) temperature records, which is five times the 866 record cold daily high (494) and low (372) temperature records, NOAA reported.
Climate Highlights — (September–November)
- The September-November contiguous U.S. average temperature was record warm at 56.8°F, 3.3°F above the 20th century average. This surpassed the previous record warm autumn of 1963 which had a temperature of 56.6°F.
- Every state across the contiguous U.S. and Alaska had an above-average autumn temperature. Forty-one states across the Rockies, Great Plains, Midwest, Northeast, and Southeast were much warmer than average. Florida tied its warmest autumn on record with a statewide temperature of 75.5°F, 3.6°F above average.
- Above-average November temperatures were widespread across the eastern half of the nation, where 32 states were much warmer than average. New Jersey had its warmest November on record with a statewide temperature of 49.7°F, 6.6°F above average.
- Connecticut, Massachusetts, New Hampshire, and Rhode Island had a record warm autumn maximum temperature.
- The autumn minimum (nighttime) temperature was 45.1°F, 3.7°F above average, the warmest on record. This bested the previous record set in 1998 by 0.3°F.
- Minimum temperature in Colorado, Florida, New Mexico, North Dakota, Nebraska, and Minnesota was record warm.
- South Carolina had its wettest autumn on record, partially driven by historic rainfall in early October. South Carolina’s autumn precipitation total was 23.62 (600mm) inches, 13.77 inches above average, and bested the previous record of 18.42 inches set in 1959.
- Based on REDTI, the contiguous U.S. temperature-related energy demand during November was 68.0 percent below average and the fourth lowest in the 1895-2015 period of record.
To avoid many overlapping or crowded dots on the map, a subset of only about 200 stations across the United States were plotted. There are many stations having “top three” or “bottom three” years that are not shown here. The stations under consideration are listed in other supplemental pages (temperature, precipitation).
