Understanding 2026's Monthly Weather Trends in the United States

In 2026, the United States experienced notable shifts in weather patterns, marked by record-breaking temperatures, significant precipitation anomalies, and the onset of a strong El Niño event.
How Did 2026's Temperatures Compare to Historical Averages?
The year began with exceptionally high temperatures. March 2026 was the warmest on record for the contiguous U.S., with an average temperature of 50.85°F, surpassing the previous record by 9.35°F. This warmth was widespread, with ten states recording their warmest March on record. (mtsinsights.com)
April 2026 continued this trend, ranking as the third-warmest April on record. The last 12 months (May 2025–April 2026) were the warmest 12-month period on record for the contiguous U.S. (ncei.noaa.gov)
What Precipitation Patterns Emerged in 2026?
Despite the warmth, precipitation patterns varied across the country. The first quarter of 2026 (January–March) was the driest on record, with precipitation less than 70% of the average. California, in particular, received less than 10% of its normal March precipitation, marking its driest March on record. (mtsinsights.com)

How Did El Niño Influence 2026's Climate?
In June 2026, the National Oceanic and Atmospheric Administration (NOAA) confirmed the onset of a strong El Niño event, expected to be among the strongest ever recorded. This phenomenon is anticipated to further elevate global temperatures through 2027 and has been linked to extreme weather events, including droughts, floods, and increased wildfire risks.
