Local Environmental Conditions
Woodland and built-up land share the area around the heart of Braintree. A nearby park adds mown lawns and planted trees to the local pollen mix. Among allergenic trees nearby, oak leads, followed by maple and birch. Grasses are a major source, with mugwort and plantain adding to the weed pollen load.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, maple and birch are in full flower. Then come the grasses, strongest in early summer and fading by early fall. Mugwort and plantain bring a final peak from midsummer into early fall. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Braintree pollen forecast updated?
The Braintree pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Braintree 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 Braintree 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 Braintree, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
