Local Environmental Conditions
Built-up land and woodland share the area around the heart of La Louvière, plus some open grassland. Allergenic trees nearby include oak, alder and maple. Grass pollen is significant here, and pigweed and plantain contribute weed pollen. In the immediate area, street trees, gardens and lawns supply most pollen in the built-up parts.
The pollen year starts in late winter, when alder flowers. Oak and maple follow in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by late summer. Pigweed and plantain bring a final peak from midsummer into mid-fall. Warm, damp weather through summer also raises mold spore levels.

How often is the La Louvière pollen forecast updated?
The La Louvière pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in La Louvière 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 La Louvière 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 La Louvière, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
