Local Environmental Conditions
The area around this location in Thief River Falls is a mix of built-up land and open grassland, plus some woodland. Close to the Thief River, riverside vegetation adds to local tree pollen. So much tree cover makes trees an important source of pollen locally. Grasses are also a significant pollen source here.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. A smaller weed peak follows from midsummer into mid-fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen. By late fall, as temperatures fall to a few degrees below freezing, pollen levels are low again.
