Local Environmental Conditions
This location in Bloomington, Minnesota, is surrounded mainly by woodland, which covers around 50% of the nearby area, with some built-up land and open grassland. A nearby park adds mown lawns and planted trees to the local pollen mix. Oak is the most prominent allergenic tree nearby, with maple and poplar also present. Beyond the trees, grasses matter a great deal, and ragweed is the main weed source.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, maple and poplar are in full flower.

Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.
