Local Environmental Conditions
Niagara Falls State Park is a gorge edge with mixed hardwood forest and spray-zone vegetation near the falls. Tree pollen peaks in May. Constant mist from the falls creates conditions where mold spores rival pollen as an allergy trigger.
Niagara Falls State Park, a landmark in Niagara Falls, opens its pollen season with maple and elm from March with birch and oak following close behind through April and May. Peak grass pollen arrives in June and July, and a modest weed pollen tail continues into September. The New England climate compresses tree, grass, and weed pollen into a shorter but intense season throughout the year.

How often is the Niagara Falls pollen forecast updated?

Does pollen in Niagara Falls 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 Niagara Falls 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 Niagara Falls, 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. |
