Summer 2026 Weather Outlook for the United States

As summer approaches, understanding the expected weather patterns can help individuals and communities prepare for the upcoming season. Here's what to anticipate for the United States in summer 2026:

What are the expected temperature trends for summer 2026?

The National Oceanic and Atmospheric Administration (NOAA) forecasts above-normal temperatures for much of the contiguous United States during the June-July-August (JJA) period. This trend is particularly pronounced in the Pacific Northwest and Alaska, where the highest probabilities of above-normal temperatures are expected. (cpc.ncep.noaa.gov)

How will precipitation patterns affect different regions?

Precipitation forecasts indicate:

• Above-normal precipitation: Elevated chances for increased rainfall are expected in parts of the Southwest, Great Basin, Central to Southern Rockies, and the Northeast. (cpc.ncep.noaa.gov)

• Below-normal precipitation: Certain areas, including the western Gulf Coast, Northern Great Plains, and Upper Mississippi Valley, may experience drier conditions. (cpc.ncep.noaa.gov)

What is the anticipated impact of El Niño on summer weather?

El Niño conditions are likely to develop during the summer of 2026, with a 61% chance of emergence in the May-June-July period. El Niño is expected to persist through at least the end of 2026. This climate phenomenon can influence weather patterns, potentially leading to warmer and drier conditions in some regions. (cpc.ncep.noaa.gov)

How might drought conditions evolve during the summer?

The Seasonal Drought Outlook suggests:

• Improvement or removal: Forecasts indicate potential drought improvement or removal in areas such as the Northeast, parts of Florida, and the coastal southern Carolinas due to expected increases in rainfall later in the summer. (cpc.ncep.noaa.gov)

• Persistence: Drought conditions are expected to persist in regions like the interior Southeast, south-central Great Plains, and parts of the Upper Midwest, with potential development anticipated in the northern Great Plains and adjacent Mississippi Valley. (cpc.ncep.noaa.gov)

What should residents and communities prepare for?

Given the forecasted above-normal temperatures and varying precipitation patterns, it's advisable for residents to:

• Stay informed: Regularly monitor updates from the Climate Prediction Center and local weather services.

• Prepare for heat: Implement heat safety measures, especially in regions expecting higher temperatures.

• Plan for potential drought: Conserve water and stay updated on drought conditions, particularly in areas where drought is expected to persist or develop.

By staying informed and proactive, communities can better navigate the challenges and opportunities presented by the summer 2026 weather patterns.
