Climate change in Bend, Oregon

Climate change is affecting locations like Bend in a variety of ways. In fall, these impacts include more extreme rainfall, changes to fall foliage, and more frequent fire weather.

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

Since 1970, average annual temperatures in Bend have gotten 2.4°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.

Since 1970, Bend's annual precipitation has decreased by 4.6 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 9, 2026, Bend has experienced 54 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).

Bend's climate threats in include:

The amount of rainfall during the heaviest rain events each year in the Northwest has increased by 1% since 1958.

Since 1970, average fall temperatures in Bend have gotten 3.3°F warmer, reflecting an overall warming trend.

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

Bend has experienced 23 more fire weather days since 1973.

Climate change is causing more frequent fire weather — a combination of hot, dry, windy conditions that prime the landscape for wildfires to ignite and spread

About 99% of Oregon is currently in drought or abnormally dry.

Rising temperatures are worsening the risk of drought in parts of the U.S.
Droughts can lead to crop failure or pasture losses, impact water supplies, affect public health, degrade ecosystems, and increase the amount of fuel for wildfires by drying grasses and forests.
The map shows the percentage of land area that is abnormally dry (category D0) or in drought (categories D1-4). This is according to the U.S. Drought Monitor's drought classification scale.

Heavier downpours

Climate change is supercharging the water cycle, driving heavier rainfall and flood risk.

Key concepts:

Climate change is supercharging the water cycle, driving heavier rainfall and flood risk.
From 1958–2021, extreme precipitation days grew in every region, led by the Northeast (+60%) and Midwest (+45%).
Intensification will continue with future warming.
Short bursts of extreme rain threaten people, ecosystems, and infrastructure nationwide.

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 fire weather

Wildfire seasons are lengthening and intensifying.

Key concepts:

Climate Central analyzed U.S. fire weather (hot, dry, windy conditions) from 1973–2024.
Wildfire seasons are lengthening and intensifying, especially in the West.
Fire weather is rising most in spring nationwide

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.
