Weather Conditions and Air Quality in Springfield, Oregon

If you’re looking to relocate to Springfield, Oregon in beautiful Lane County, you’ll want to know what the weather, air quality, and temperature in Springfield, Oregon are like. This section will tell you everything you need to know about Springfield’s climate and weather conditions.

The air quality in Springfield is average.

The average Springfield, Oregon air quality is somewhat moderate throughout the year, though it may vary slightly from season to season. In the spring, the air quality is fairly good, but it can be poor at times (particularly right before pollen season hits). During summer, it tends to be moderate as well; however, there are still some days where it becomes unhealthy for sensitive groups or extreme conditions occur. Fall brings even more stable weather and better conditions overall for most people’s respiratory health. Winter typically sees lower temperatures and therefore less pollutants in the air, so you might find yourself breathing easier during this time of year!

Pollen is moderate most of the year.

Because of its generally warm climate and high elevations, Springfield has a longer growing season than most places in the country. As a result, it is home to many kinds of plants that produce abundant amounts of pollen. The combination of warm temperature and high humidity causes pollen to clump together and fall more quickly than in other parts of the country.

Springfield’s pollen season begins in February and lasts through the end of May; it varies by year, but usually ends before the start of June. The worst times are usually during April and May when the temperature is warm enough for trees to bloom, but still cold enough that they don’t lose their leaves yet.

The time period after spring also has high pollen counts because some plants go into production as soon as they can grow again after winter ends (e.g. hay fields).
