Local Environmental Conditions
This part of Worcester is surrounded mainly by woodland, with some open grassland and built-up land. A nearby park adds mown lawns and planted trees to the local pollen mix. Allergenic trees nearby include birch, maple and oak. Grass pollen is plentiful, while mugwort leads among the weeds. In the built-up parts of the area, street trees, gardens and park lawns add to the local mix.
Birch, maple and oak lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Mugwort brings a final peak from midsummer into early fall. By late fall, pollen levels are low again.

How often is the Worcester pollen forecast updated?
The Worcester pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Worcester 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 Worcester 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 Worcester, 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. |
