Local Environmental Conditions
The area around this part of Roscoe Township is mostly woodland, with a good deal of open grassland. Close to a watercourse, riverside vegetation contributes to what is in the air. Of the trees nearby, maple is the one that matters most for allergies. Grasses add a sizeable share of the local pollen.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in early summer and keep pollen in the air into early fall. A smaller weed peak follows from early summer into early fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.
