Local Environmental Conditions
Around Town of Webster, this area sits apart from mapped forest, water, or parkland, leaving grass and ragweed as the more probable dominant allergens. Local wind exposure and land use can shift the exact mix slightly from block to block. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
For Town of Webster, grass pollen takes over next, building to a peak around June, then gives way to ragweed, which drives the season's second major surge from mid-August into October. Neighboring parts of the county typically see this same sequence with only minor timing shifts. The overall order of species tends to hold steady, even as exact dates shift slightly each year.
