Local Environmental Conditions
Surrounding West Lancashire farmland contributes substantial grass and tree pollen, moving into town when winds blow from the east. On top of that, birch and sycamore are the two species driving most tree pollen in Skelmersdale, especially around parks and green corridors. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.
The tree pollen story in Skelmersdale is really about birch and sycamore, in that order. Expect birch pollen roughly from March to May, while sycamore follows on from April to June. After that, grass pollen carries the season from May through to September, with June and July normally the toughest stretch. Useful to know if you tend to feel it every spring.

Does pollen in Skelmersdale 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 Skelmersdale 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 Skelmersdale, 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. |
