Air Quality and Average Temperature in Eugene, Oregon

We all know that Eugene has beautiful weather, but what about the air quality? While Eugene’s average temperature, weather, and climate are great overall, some say it appears polluted compared to other small US cities. But it isn’t all bad news since Eugene’s air quality has been improving for the last few years. And as you read on, you’ll find out more about the air quality in Eugene.

Eugene, Oregon, is a beautiful city with a variety of fun things to do. If you’re planning to visit or move to Eugene, we have some important information for you. Below, you’ll learn more about Eugene’s temperature, weather, and life in this metropolis.

Eugene Air Quality Assessment and Facts: How Bad is Eugene’s Air?

Understanding the distinction between polluted emissions and observed air quality levels is crucial for understanding Eugene’s air quality. When evaluating air quality, climatic variables like wind, rain, and temperature can have a massive effect. This is due to the crucial role that the weather and temperature serve in the spread of pollution.

For instance, although rainfall and wind may distribute and reduce pollution levels, their absence can lead to emissions building up. The state of the temperature can also have a similar effect.

In Eugene, Oregon, short-term particulate matter (PM2.5) has cost the city more than any other emissions. The annual average for PM2.5 days in Eugene is 6.2, almost twice the regulatory guideline of 3.2 days.

PM2.5 is a collective term for atmospheric smaller-than-2.5-micron-diameter particles, such as tar, smoke, soot, dust, allergens, and toxins. Unlike gasses and other frequently detected harmful emissions, PM2.5 is classified according to its size instead of its chemical composition. This is because PM2.5 refers to particles that are so tiny they can pass through the causeways in our nostrils and lungs and circulate in our bloodstream.

The Willamette Valley’s grass seed fields contribute particles to Eugene’s PM2.5 pollution. This pollutant also originates from industrial and vehicle fumes, combustion byproducts and residue, air-borne pollen and chemicals from farmland, and sub regional emissions from nearby towns and states.

Although the air quality in Eugene only falls short of the Environmental Protection Agency (EPA) standards for short-term PM2.5 pollution, other emissions indicators also need to be improved.

Which Months Have the Highest PM2.5 Emissions?

Because of home wood fires, PM2.5 emissions in Eugene often peak in the winter, early fall, and late summer, coinciding with the wildfire season. With PM2.5 values of 21.7 g/m3 and 16.8 g/m3, respectively, which are around 4 – 5 times more than July averages, November and December were Eugene’s most polluted months in 2019.

These elevated observed values are primarily caused by climatic factors that retain small particles in the air instead of a rise in total emissions.

How is Eugene, Oregon Improving its Air Quality?

With the help of several strategies, Eugene has reduced daily emissions throughout the city. The two biggest improvements have been made by attempts to switch citizens over to electric vehicles and sustainable power.

Incentives for Electric Vehicles

In US cities, automobiles are typically the biggest cause of air pollution, adding to dangerous atmospheric PM2.5 and ozone. Electric and hybrid cars provide a way to reduce emissions from this industry. Oregon encourages the use of electric cars using incentive schemes that offer consumers up to $5,000 in savings, which will continue to positively impact the Eugene air quality over time.

Sustainable Electricity

One of the country’s most environmentally friendly power grid assets serves Eugene well.

Hydroelectric energy, which produces no carbon dioxide or atmospheric pollution, provides around 80% of Eugene’s renewable sources.

Furthermore, more traditional power sources account for the remaining 20%. Fossil fuels provide almost no energy. Currently, among one of the world’s top safest electricity towns, Eugene eliminated coal-fired energy facilities and switched to renewable energy sources.

Pro Tip

Although “weather” and “climate” are distinct, many people mix them.

  • Weather is the atmosphere’s behavior and how it affects daily operations and living. The weather may vary minute by minute.
  • Moreover, the long-term weather pattern in a location is referred to as the climate. Climate can refer to the typical conditions for a given area and time period over 30 years.
