Pollen Surge Hits South Dakota as Spring Allergies Peak

Spring has arrived in South Dakota, but for millions of residents, the season brings more than blooming flowers and warming temperatures—it brings sneezing, congestion, and itchy eyes. Pollen counts have reached elevated levels across the state, triggering a wave of seasonal allergies as trees and grasses release their pollen into the air.

According to allergy tracking data, South Dakota's allergy season peaks between April and June, with September marking a secondary surge. Tree pollen dominates spring allergies in the state, followed by grass pollen in summer months. Residents experiencing fall symptoms typically face weed pollen triggers. The symptoms are widespread: stuffy or runny noses, itchy and watery eyes, congestion, coughing, headaches, sneezing, and even brain fog.

Nationally, about 1 in 3 adults and 1 in 4 children are dealing with seasonal allergies, according to health experts. For South Dakota residents managing these symptoms, timing outdoor activities is critical. Pollen counts tend to peak during morning and afternoon hours, making evening the optimal time for outdoor activities during peak allergy season.

Health officials recommend residents monitor daily pollen counts and adjust their outdoor exposure accordingly. Over-the-counter medications provide temporary relief, but experts suggest consulting with healthcare providers about long-term allergy treatment plans. For those traveling to South Dakota during peak allergy months or managing symptoms at home, creating a personalized allergy management strategy before conditions worsen can help minimize disruption to daily life.

South Dakota's allergy season typically continues until the first frost of winter, giving residents several months of potential triggers ahead.
