Local Environmental Conditions
Around 98% of the area near the center of Town of Cortlandt is woodland. Close to running water, riverside trees such as plane tree contribute to what is in the air. Of the allergenic trees nearby, maple matters most, while oak and plane tree also contribute. Grasses also feature strongly, alongside mugwort among the weeds.
Maple, oak and plane tree lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Later, mugwort keeps weed pollen in the air from midsummer into early fall. By late fall, pollen levels are low again.

How often is the Town of Cortlandt pollen forecast updated?

Does pollen in Town of Cortlandt 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 Town of Cortlandt 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 Town of Cortlandt, 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.
