Local Environmental Conditions
The heart of Colliers Wood is surrounded mainly by built-up land, which covers around 71% of the nearby area, with some woodland. Among allergenic trees nearby, plane tree leads, followed by maple and oak. Grasses also feature strongly, alongside plantain and pellitory among the weeds. Compared with most places, birch is especially widespread here, which makes it one of the key local allergens.
Plane tree, 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 15°C, and their pollen lingers into late summer. The season closes with plantain and pellitory from late spring into late summer. The birch period in mid-spring is usually the most intense time of year here.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Colliers Wood 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 Colliers Wood, 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.

| 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. |
