Local Environmental Conditions
Most of the area around this site in Boston is woodland, with a good deal of built-up land. Allergenic trees nearby include maple, oak and birch. Grasses are a major source, with mugwort and ragweed adding to the weed pollen load. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
Maple, oak and birch lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by early fall. The most intense period comes from midsummer into early fall, when mugwort and ragweed are in flower. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Boston pollen forecast updated?
The Boston pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Boston 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 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, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
