Local Environmental Conditions
The nearby coastal fringe adds further grass and tree pollen exposure, particularly under the area's changeable Atlantic weather. On top of that, oak and birch are the two species driving most tree pollen in Highbury, especially around parks and green corridors. This combination means residents feel both urban and rural pollen sources depending on which way the wind's blowing.
Highbury's pollen year has two main tree culprits: oak first, birch close behind. Don't forget grass, either — it runs May to September and usually causes the most trouble in June and July. Oak pollen typically runs from April to May, before birch takes over, usually March to May. Something to plan around if pollen usually gets to you.

How often is the Highbury pollen forecast updated?

Does pollen in Highbury 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 Highbury 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 Highbury, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
