Coldest (Norfolk, VA) and Warmest (Phoenix, AZ) HDD Observations for U.S. Meteorological Winter 2025-26

Reviewing the Climate Impact Company U.S. heating degree day (HDD) count for selected cities reveals the coldest location for meteorological winter 2025-26 was Norfolk, VA where 117.4% of the 30-year normal HDD was observed. Values above 110% are considered MUCH BELOW normal temperature (or MUCH HIGHER than normal heating demand). Norfolk was followed closely behind by New York City (117.0%), Baltimore, MD (114.3%), Richmond, VA (114.2%) and Hartford, CT (113.7%).
