Set on the southwestern shore of Cape Cod, Falmouth's landscape is defined by pitch pine and oak woodland alongside bayberry and salt marsh cordgrass, the main contributors to seasonal pollen exposure. Local parks and open ground tend to see higher pollen counts than the denser urban core. Microclimates within the area can shift the timing slightly from one neighborhood to the next.

How often is the Falmouth pollen forecast updated?

Does pollen in Falmouth 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 Falmouth 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 Falmouth, 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.
