Local Environmental Conditions
Around Town of Westford, hazel and willow crowd the water's edge, both classic sources of early allergenic pollen; this sits nearby. Year-to-year swings in rainfall and wind can shift this picture somewhat either way. Comparable land cover in surrounding areas tends to produce a similar pollen mix overall. Local microclimate and soil conditions can push these figures slightly higher or lower.
At Town of Westford, the water-adjacent hazel and willow are early risers, getting an early start, typically cresting between February and March. By late spring, grass pollen is climbing steadily toward a June high point, and ragweed later takes the lead from mid-August through October. This general pattern holds fairly steady across the surrounding county from year to year.
