In Survey Of 195 US Cities, Average Winters Nine Days Shorter Compared To 1970-1997 Baseline

For the millions of people across the United States who have spent the last month digging themselves out of above-average levels of snow and ice, this winter has felt especially long and harsh. But the typical winter is actually getting shorter in 80% of major US cities scrutinized by researchers, according to new data released by Climate Central, an independent climate science and communication group.

Researchers found that across 195 US cities, winters are on average nine days shorter today than they were from 1970 to 1997, as the climate crisis progresses. For the purposes of the study, analysts defined winter as the coldest 90 consecutive days of the year during the past period, 1970-1997, and then compared the frequency of winter-like temperatures during the most recent 28-year period, 1998-2025. Across the country, they found that winter-defining temperatures are arriving later and ending earlier than in the 20th century.

Cities across the US south-east, north-east, upper midwest and south have experienced the largest average decrease in winter days, according to the research. Juneau and Anchorage in Alaska have seen winters shrink the most, by 62 and 49 days, respectively. Approximately 15% of the 295 cities analyzed saw winters lengthen, particularly along the California coast and in the Ohio valley.

Warmer, shorter winters have significant consequences for both humans and the environment, including reduced water supply, decreased summer crop yields and worsening allergy seasons. “These are not just impacts that you see when you look out the window or affect if you are able to drive into work,” Barlow said. “These are also pretty substantial changes to ecosystems, the health of our natural community and our water resources.” Shorter winters are also creating challenges for local economies. The multibillion-dollar winter recreation industry faces challenges from rising temperatures and reduced snow and ice cover. In certain parts of Colorado, ski resort visits are down 20% this year amid severe snow drought.
