Local Environmental Conditions
Mouscron's parks and the Mouscron River corridor oak and linden are the leading pollen sources, with grass becoming significant from late spring onward. The Wallonia farmland nearby and any local parks both shape how exposure varies across the area.
From an early hazel and alder start, Mouscron's pollen season builds to a oak and linden peak in spring before grass extends exposure into early summer; January through August covers the full window. Calmer, drier days tend to let pollen linger longer here than in windier weather.

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