Local Environmental Conditions
In Big H Campground, along the damp banks, hazel and willow release some of the year's first tree pollen; this sits within the neighborhood. Actual counts still shift year to year with temperature, rainfall, and prevailing wind. Local readings for the surrounding area tend to follow this same general pattern.
Around Big H Campground, the waterside hazel and willow are consistently first to release pollen each year, peaking in late winter through March. Grass pollen rises through late spring toward a June high point, before ragweed's late-summer surge carries the season into October. This general pattern holds fairly steady across the surrounding county from year to year.
