Local Environmental Conditions
Around 41% of the area near the heart of Dayton, Minnesota is farmland, with a good deal of woodland and some open grassland. The damp ground beside a stream or river nearby supports trees such as poplar, adding to local pollen. Allergenic trees nearby include maple, oak and poplar. Grasses are a major source, with ragweed adding to the weed pollen load.
Tree pollen peaks in mid-spring, when the weather warms to around 5°C and maple, oak and poplar are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. The season closes with ragweed from late summer into mid-fall. Rain is heaviest in summer, often giving short breaks from high pollen levels. By late fall, pollen levels are low again.
