Climate change in Dallas, Texas

Climate change is affecting locations like Dallas in a variety of ways. In fall, these impacts include changes to fall foliage, more unusually warm days, and more intense hurricanes.

Explore these pages to learn how people in Dallas are at risk in a warming world.

Since 1970, average annual temperatures in Dallas have gotten 3.9°F warmer, reflecting an overall warming trend.

Warming puts people and ecosystems at risk from more frequent and intense extreme weather.
Overall, the contiguous U.S. is about 2.8°F warmer today than in 1970, based on average temperatures.
Data source: NOAA ACIS

Since 1970, Dallas' annual precipitation has increased by 3.8 inches.

Climate change is supercharging the water cycle and bringing heavier precipitation extremes across the U.S.
For every 1°F of warming, the air can hold 4% more moisture, increasing the chances of heavier downpours that contribute to flash flooding hazards.
Data source: NOAA ACIS

As of October 3, 2026, Dallas has experienced 84 days this year with temperatures made twice as likely by climate change.

This is according to the Climate Shift Index (CSI), which quantifies the influence of human-caused climate change on daily average temperatures. Temperatures on these days had a CSI level 2 or higher, which indicates local temperatures were at least two times more likely due to climate change.
The CSI ranges from -5 to +5. Positive levels indicate temperatures made more likely due to climate change (while negative scores indicate conditions made less likely).

Dallas' climate threats in include:

During the past 20 years, Texas experienced 96 more billion-dollar disasters from severe storms compared to the previous 20 years.

As the planet warms, extreme weather events are becoming more frequent and intense, resulting in devastating losses.
This data shows how the total number of severe storms with at least one billion dollars in damages has changed from 1980-1999 to 2005-2024.

Dallas has experienced 13 more extremely hot days (with temperatures above 99.0°F) since 1970.

More frequent and intense extreme heat — the deadliest type of weather in the U.S. — is a direct result of a warming planet.
Extremely hot days are defined as days with maximum temperatures hotter than 95% of local temperatures from 1991-2020.
Data source: NOAA ACIS

Between 1980 and 2024, Texas experienced 16 billion-dollar hurricanes.

As the planet warms, extreme weather events are becoming more frequent and intense, resulting in devastating losses.
Tropical cyclones (which include hurricanes and tropical storms) are the most costly extreme weather events in the U.S.
This data shows the total number of hurricanes with at least one billion dollars in damages that occurred during 1980-2024.
Data source: NCEI U.S. Billion-Dollar Weather and Climate Disasters

Since 1970, average fall temperatures in Dallas have gotten 4.1°F warmer, reflecting an overall warming trend.

Fall warming means that risky heat, fire weather, and allergies linger later into the year.

Explore some ways climate change is affecting Dallas in fall

Impacts to fall color

Conditions that trigger fall color are shifting with climate change.

Key concepts:

Foliage depends on temperature, day length, and rainfall — as well as other conditions including extreme weather events.
Cool fall nights can boost color, but they have warmed 2.7°F (1970–2023) in 212 U.S. locations.
Warmer falls can delay or shorten peak foliage.

More warm fall days

Fall (September-November) has warmed nationwide since 1970.

Key concepts:

Fall (September - November) has warmed nationwide since 1970.
Warming is nationwide, strongest in the Southwest.
Hotter falls extend risks from heat, wildfire, allergies, and more.

More intense hurricanes

Warmer oceans from climate change fuel stronger hurricanes.

Key concepts:

Warmer oceans from climate change fuel stronger Atlantic hurricanes with heavier rain and higher storm surge.
Rising seas amplify storm surge, increasing risks for coastal residents.
Warmer air holds more moisture, driving heavier downpours and flooding.

Changes in severe storms

Certain conditions favorable to thunderstorms and tornadoes are occurring more often

Key concepts:

Severe storms make up half of U.S. billion-dollar disasters since 1980.
Climate change is shifting storm conditions into new seasons and regions.

Impacts to food prices

Extreme events fueled by climate change can damage crops, reduce yields, and disrupt supply chains.

Key concepts:

Food and climate change are closely linked. Food systems account for about one-quarter of all heat-trapping pollution.
Meanwhile, extreme events fueled by climate change can damage crops, reduce yields, and disrupt supply chains — all of which can drive food prices higher.
The availability, quality, and affordability of food reflect a complex set of climatic and socioeconomic factors. Emerging research is providing insight into the role of climate change.
