Local Environmental Conditions
The landscape around the heart of Roanne is densely built up. Common allergenic trees nearby include willow, poplar and maple. Grasses also feature strongly, alongside ragweed and pigweed among the weeds. Locally, planted trees and mown lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and willow, poplar and maple are in full flower. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into late summer. Later, ragweed and pigweed keep weed pollen in the air from late summer into mid-fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.

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