Haverhill's Merrimack River valley setting features oak, maple, and birch as the main tree pollen sources, with exposure varying between the wooded hillside residential areas and the more built-up Merrimack River valley commercial and industrial corridors. The Merrimack River corridor is a particularly significant local source, while the hilltop-to-river elevation gradient creates distinct pollen exposure differences between the forested ridges and the urban river valley below.

How often is the Haverhill pollen forecast updated?

Does pollen in Haverhill come from nearby or far away?

Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.

Are pollen levels in Haverhill 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 Haverhill, 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.
