Local Environmental Conditions
Around Governor Thompson State Park Campground, a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen, just around the area. Located within the neighborhood's edge, this area has oak and birch trees, with birch pollen especially potent during its brief spring window. Local microclimate and soil conditions can push these figures slightly higher or lower.
In Governor Thompson State Park Campground, along the waterway, hazel and willow release pollen first, climbing steadily from late winter into March. Woodland oak and birch pick up the pace next, through mid-to-late spring, cresting around April and May in the year's sharpest tree-pollen spike. Grass pollen rises through late spring toward a June high point, before ragweed's late-summer surge carries the season into October.

Are pollen levels in Town of Stephenson based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Town of Stephenson, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.
