Local Environmental Conditions
Bernay's tree cover, concentrated in parks and along the Seine, is dominated by birch and oak. Nearby dairy pasture and orchard bocage add significant grass pollen exposure through the growing season, while the oceanic climate shapes how pollen disperses across the town.
Bernay sees its pollen season begin in late winter, with hazel and alder the first to appear, then peaks with birch and oak across April and May, before grass from pasture then dominates into early summer, a rhythm shaped by the area's oceanic climate.

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

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
