How to connect?

Medford's Mystic River valley setting in the Greater Boston metropolitan area features oak, maple, and ash as the main tree pollen sources, with the dense suburban tree canopy and riverside parks shaping local exposure. New England's classic hardwood forest produces a pronounced spring tree pollen peak, while ragweed and grass pollen contribute through late summer.

Mugwort extends exposure into September, while the enclosed Rogue Valley concentrates pollen under calm conditions and the hot, dry Medford summer is more intense than in western Oregon cities, suppressing but not eliminating late-season exposure.
How often is the Medford pollen forecast updated?

Does pollen in Medford 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 Medford 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 Medford, 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.
