Local Environmental Conditions
Grass pollen from surrounding Lancashire fields is significant through the summer months, carried in by the region's typical south-westerlies. On top of that, birch and oak are the two species driving most tree pollen in Fleetwood, especially around parks and green corridors. The relatively open, low-lying landscape lets pollen disperse readily across the area through the season.
In Fleetwood, the pollen calendar starts with birch and rolls straight into oak. Grass season overlaps a lot of this too, running May through September and peaking mid-summer. Birch pollen typically runs from March to May, with oak picking up between April and May. Worth factoring in if hay fever's ever been an issue for you here.

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