Local Environmental Conditions
Most of the area around the center of Greenwich is woodland, with a good deal of built-up land and some open water. The damp ground beside a watercourse nearby supports trees such as plane tree, adding to local pollen. Plane tree heads the list of allergenic trees nearby, ahead of olive. Grasses and weeds such as pigweed and pellitory round out the local mix.
Plane tree and olive lead the season in early spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in mid-spring, with temperatures around 20°C, and their pollen lingers into mid-fall. Pigweed and pellitory bring a final peak from early summer into early fall. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

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