Moderate Pollen in Sioux Falls, SD

About pollen in Sioux Falls

Tree pollen is the main source of allergy activity in Sioux Falls today, registering at a moderate level. This means those who are sensitive to tree pollen, especially allergy sufferers reacting to ash, maple, oak, celtis, or cottonwood, may notice some mild symptoms, while others likely won't be affected much at all. Looking ahead, tree pollen is expected to hold steady at this moderate level over the next stretch of days. This is a bit unusual for mid-November, since tree pollen typically peaks in spring; a late-season release from local trees like these can sometimes occur as temperatures fluctuate before winter fully sets in. Grass and ragweed are not factors this time of year, so tree pollen remains the one to watch for now.

What to do today

• Pollen is moderate today; sensitive people should limit long stretches outdoors, especially in the afternoon.
• Shower and change clothes after spending time outside.
• Keep windows closed during the highest-pollen hours.
