Local Environmental Conditions
A stretch of hazel and willow lines the water, feeding some of spring's earliest pollen; this sits close to home here. Located within the neighborhood, this area has tree cover made up mostly of oak and birch, both significant spring allergen sources. Nearby, within the local area, green space with maintained lawn and planted trees, both contributing to grass and ragweed counts.
Hazel and willow near the water open the pollen calendar early, reaching its high point sometime in late winter or early spring. Woodland oak and birch pick up the pace next, through mid-to-late spring, reaching its high point through April and into May. As spring turns to summer, grass pollen rises toward its June high, handing off to ragweed, which peaks from mid-August through October.

Does pollen in Revere 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 Revere 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 Revere, 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. |
