Malden's Boston suburban Massachusetts setting features oak, maple, and sweetgum as the main tree pollen sources, with exposure varying between the limited wooded Middlesex Fells Reservation fringe residential areas and the more built-up commercial corridors along Commercial Street. The Middlesex Fells Reservation to the west is a particularly significant local tree pollen source, creating distinct pollen gradients between the forested reservation edge and the more urbanized downtown areas.

Does pollen in Malden 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 Malden 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 Malden, 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.
