Local Environmental Conditions
The heart of Niort is densely built up, with some woodland. Close to the Niortaise River, riverside trees such as willow and alder add to local tree pollen. Of the trees nearby, maple, hazel and alder are the ones that matter most for allergies. Grass pollen is plentiful, while pellitory and plantain lead among the weeds.
First to flower are hazel and alder, in late winter. Maple follows in early spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer and keep pollen in the air into early fall. Pellitory and plantain flower through much of the warmer half of the year. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Niort pollen forecast updated?

Does pollen in Niort 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 Niort 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 Niort, 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. |
