Caribou's setting on broad potato-farming country in far northern Maine supports potato fields, spruce-fir woodlots, and roadside grasses as the leading local vegetation, all factoring into the pollen count through the year. Wind patterns across the area help determine how far pollen travels from these source plants. None of this differs sharply from one year to the next barring unusual weather.

Does pollen in Caribou 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 Caribou 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 Caribou, 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.
