Local Environmental Conditions
This location in Lake Mack-Forest Hills is surrounded mainly by woodland, which covers around 86% of the nearby area. With Lake Mack-Forest Hills nearby, lakeside vegetation along its shore contributes to the local mix. The surrounding woodland makes trees an important local pollen source. Grass pollen adds noticeably to the overall load.
Tree pollen comes first, peaking in early spring. Grasses take over in early spring, with temperatures around 20°C, and their pollen lingers into mid-fall. A smaller weed peak follows from early summer into early fall. Mold spores join in from midsummer into early winter, when damp, warm spells let them thrive.
