Local Environmental Conditions
Built-up land makes up around 42% of the area near the center of Ploërmel, with a good deal of woodland and some open grassland. Woodland on all sides makes trees an important local pollen source. Grass pollen adds noticeably to the overall load. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Flowering trees bring the first pollen of the year in mid-spring. Grasses take over in early summer and keep pollen in the air into late summer. A smaller weed peak follows from midsummer into mid-fall. By early winter, as temperatures fall to around 5°C, pollen levels are low again. Dry, sunny and breezy weather raises levels within each period, and steady rain brings them down.

How often is the Ploërmel pollen forecast updated?

Does pollen in Ploërmel 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 Ploërmel 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 Ploërmel, 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. |
