Local Environmental Conditions
This mix of urban and rural influence gives Colne a fairly typical pollen pattern for the wider region. That's on top of birch and oak, which are the main local tree pollen sources around Colne's parks and quieter streets. Local farmland and hedgerows nearby add meaningful grass pollen through late spring and summer, especially under moist Atlantic fronts.
Colne's pollen year has two main tree culprits: birch first, oak close behind. Grass pollen then stretches from May into September, with the worst of it typically landing in June and July. Birch tends to release pollen between March and May, and oak keeps things going from April right through to May. Useful to know if you tend to feel it every spring.

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