Frequently asked questions about Oregon pollen forecasts

How often should I check the pollen forecast in Oregon?
If you are sensitive to seasonal allergies in Oregon, it helps to check the pollen forecast daily during peak allergy seasons. Weather changes, wind, rainfall, and temperature swings can all shift pollen exposure from one day to the next.
Why can pollen counts vary across cities in Oregon?
