Local Environmental Conditions
Located within the neighborhood, this area has hazel and willow grow along the bank, contributing some of the season's earliest allergenic pollen. Located close by, this area has a park combining lawn grass and planted trees, both minor but real contributors to pollen here. Seasonal timing here generally tracks the wider region, give or take a week or so.
The bank's hazel and willow kick off the pollen season ahead of the rest, arriving ahead of the rest of the season, cresting around late winter. Grass pollen builds through late spring and peaks in June, and then ragweed picks up the slack, running from mid-August through October. Exact peak dates shift by a few weeks year to year depending on temperature and rainfall.

Does pollen in Falcon Heights 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 Falcon Heights 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 Falcon Heights, 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/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
