Monthly Attribution Overview February 2025

In February 2025, U.S. temperature anomalies were split, with 92 cities warmer and 99 cooler than the 1991-2020 normal. Despite an average anomaly of -0.3°F and significant cold in the Northern Rockies and Plains, no city set a low temperature record for the month. Conversely, Phoenix, Arizona, recorded its hottest February on record. Analysis using the Climate Shift Index (CSI) indicates that temperatures in many cities remained warmer than they would have been without climate change, as more cities experienced days with positive than negative CSI values. Long-term trends show that 189 out of 191 analyzed stations have warmed since 1970, with Juneau, Alaska, being the fastest-warming station for February.

• Temperature anomalies across 191 analyzed U.S. cities in February 2025 were divided, with 92 cities warmer than normal and 99 cooler than normal, resulting in an average temperature anomaly of -0.3°F.
• While cities in the Northern Rockies and Plains were on average 7.3°F cooler than normal, no city in the analysis set a low temperature record for February. In contrast, Phoenix, Arizona, set a record for its hottest February.
• Climate change continued to influence temperatures despite the overall cold anomalies; more cities experienced days with positive Climate Shift Index (CSI) values than negative ones, and the average number of days with a CSI of 3 or higher exceeded those with a CSI of -3 or lower.
• Long-term data indicates a widespread warming trend in February since 1970, with 189 of the 191 analyzed ACIS stations showing positive trends. Juneau, Alaska, is identified as the fastest-warming station for February, increasing by 9.6°F on average since 1970.
