Plymouth's coastal Massachusetts setting features oak, pine, and maple as the main tree pollen sources, with exposure varying between the wooded inland residential areas and the more open coastal zones along Plymouth Bay. The Atlantic Ocean proximity creates temperature gradients that modify pollen dispersal, while the coastal pine barrens contribute distinctive pine pollen locally and the bay position provides periodic relief through onshore breezes.

The coastal New England setting means the season is slightly moderated compared to more inland locations, while frequent Atlantic rainfall provides regular interruptions throughout.
How often is the Plymouth pollen forecast updated?

Does pollen in Plymouth 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 Plymouth 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 Plymouth, 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.
