The first freeze is occurring later in many parts of the United States

Many US cities are recording their first 32° F days later in the year, based on each location's long-term trend from 1970 to 2023, according to an analysis by Climate Central, a nonprofit research and communications group.

An arrow map showing about 200 larger US cities by when the first 32º F temperatures arrived in 2023 versus 1970.
Note: Change in the first freeze is calculated as the linear trend in first 32° F dates from 1970 to 2023 multiplied by the length of the record — not a direct 1970 versus 2023 difference. Cities in Alaska and cities with infrequent freeze events are not shown.
