Local Environmental Conditions
Most of the area around the center of Montélimar is built-up land, with a good deal of woodland. Common allergenic trees nearby include oak, poplar and ash. Grass pollen is significant here, and ragweed and mugwort contribute weed pollen. Ragweed is unusually common here compared with most other locations, making it a particularly important local pollen source.
Oak, poplar and ash lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in early summer and easing off by early fall. The most intense period comes from late summer into mid-fall, when ragweed and mugwort are in flower. By late fall, as temperatures fall to around 10°C, pollen levels are low again.

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