Local Environmental Conditions
The area around the heart of Honfleur is a patchwork of woodland, built-up land and open grassland. Of the allergenic trees nearby, willow matters most, while birch also contributes. Grasses and weeds such as plantain and pigweed round out the local mix. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
Tree pollen peaks in early spring, when the weather warms to around 10°C and willow and birch are in full flower. Grasses take over in early summer, with temperatures around 15°C, and their pollen lingers into late summer. Later, plantain and pigweed keep weed pollen in the air from late spring into early fall. Warm, damp weather from early summer into early fall also raises mold spore levels.

How often is the Honfleur pollen forecast updated?

Does pollen in Honfleur 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 Honfleur 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 Honfleur, 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. |
