Local Environmental Conditions
The area around the heart of Bromley is a mix of built-up land and woodland. Of the trees nearby, oak, maple and birch are the ones that matter most for allergies. Plantain and pigweed are the main local weed pollen sources. Compared with most places, oak is especially widespread here, which makes it one of the key local allergens.
Oak, maple and birch lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. The season closes with plantain and pigweed from late spring into late summer. The oak period in late spring is usually the most intense time of year here. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

How often is the Bromley pollen forecast updated?

Does pollen in Bromley 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 Bromley 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 Bromley, 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. |
