Monthly Weather Trends Guide for the United States in 2026
Understanding the anticipated weather patterns for 2026 is essential for planning and preparedness. This guide provides an overview of expected temperature anomalies, precipitation forecasts, and regional climate influences across the United States.
January 2026: A Warm Start to the Year
January 2026 is projected to begin with temperatures significantly above the 1850-1900 pre-industrial baseline. The North American Multi-Model Ensemble (NMME) forecasts global temperatures rising to nearly 1.8°C above this baseline by the end of 2026, with a strong likelihood of above-normal temperatures across the U.S. during the winter months.

February 2026: Persistent Warmth and Drought Conditions
In February, the warmth continues, with forecasts indicating above-normal temperatures across most of the U.S. The development of El Niño conditions in the tropical Pacific is expected to influence global temperatures, contributing to the warmth. Precipitation during this period is anticipated to be below normal, with the south-central U.S. and Southeast experiencing significant drought conditions. (climatecentral.org)
March 2026: Transition to Spring and Energy Implications
March marks a transition to spring, but the warmth persists. The NMME projects global temperatures to remain steady before increasing again by late boreal summer. The Pacific Northwest is expected to experience above-normal temperatures, with a 90% chance of this occurring by August. This prolonged warmth leads to increased cooling degree days, indicating higher energy demand for air conditioning. (climatecentral.org)
April 2026: Elevated Fire Risks and Marine Heatwaves
April brings continued warmth, with cities in the western U.S. experiencing more days with temperatures at least twice as likely due to human-caused climate change. A persistent marine heatwave off the coasts of California and Mexico is expected to continue, with conditions at least six times more likely due to climate change. This combination of factors elevates the risk of wildfires, particularly in the interior mid-Atlantic, southern Appalachians, and parts of the Southeast. (climatecentral.org)
May 2026: Intensifying El Niño Effects
By May, the El Niño pattern is expected to strengthen, leading to above-normal temperatures across nearly the entire United States during the summer months. The highest confidence for significantly above-average temperatures appears centered over the Pacific Northwest. This warming trend is associated with the development of a potentially very strong El Niño in the tropical Pacific later in 2026. (wusf.org)
June to August 2026: Hot and Dry Conditions
The summer months are projected to be characterized by above-normal temperatures across the U.S., with the Pacific Northwest experiencing the most significant anomalies. The development of El Niño conditions is expected to influence global temperatures, contributing to the warmth. Precipitation patterns are anticipated to be below normal, with the south-central U.S. and Southeast continuing to experience drought conditions. (wusf.org)
September to December 2026: Cooling and Potential for El Niño Persistence
As the year progresses into the fall and winter months, temperatures are expected to gradually decrease but remain above historical averages. The persistence of El Niño conditions may continue to influence weather patterns, potentially leading to warmer-than-normal temperatures and altered precipitation patterns in certain regions.

Regional Highlights
-
Northeast and Great Lakes: A cooler start to spring with late-season snow and frost potential; some flooding likely later from snowmelt and rain. (accuweather.com)
-
Southeast and Mid-Atlantic: Early-spring fire risk in the interior mid-Atlantic, southern Appalachians, and parts of the Southeast. Drought concerns early, followed by increasing rain and flood risk along the Gulf Coast. (accuweather.com)
-
Pacific Northwest: Above-normal temperatures are expected, with a 90% chance of this occurring by August. (climatecentral.org)
Conclusion
The year 2026 is anticipated to be marked by above-normal temperatures across the United States, influenced by developing El Niño conditions. These patterns are expected to lead to increased energy demand, elevated fire risks, and ongoing drought conditions in certain regions. Staying informed and prepared for these conditions is crucial for residents and businesses alike.
