Local Environmental Conditions
The waterway's edge supports hazel and willow, species known for potent, wind-carried pollen, within 50m of this spot. Here, only about 150 meters off, tree cover made up mostly of oak and birch, both significant spring allergen sources. Nearby weather stations report comparable trends across the broader stretch of the county.
Hazel and willow by the water are typically first out of the gate, hitting its peak before most trees have even budded, around late winter into March. Oak and birch nearby take over the pollen calendar through mid-spring, reaching its high point through April and into May. 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.

Does pollen in Boston 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 Boston 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 Boston 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. |
