Local Environmental Conditions
Here, in the surrounding area, the nearest stream or river hosts hazel and willow, two of the most allergenic early-season trees. Here, in the vicinity, maintained parkland where turf grass and ornamental species add to the grass and ragweed mix. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
Along the waterway, hazel and willow release pollen first, topping out well before most other trees start releasing pollen, around February and March. Moving into early summer, grass pollen climbs to its seasonal high in June, then yields to ragweed, the dominant late-summer and fall allergen through October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

How often is the Troy pollen forecast updated?

Does pollen in Troy 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 Troy 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 Troy, 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.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
