Local Environmental Conditions
The vegetation around Lecco, on the eastern shore of Lake Como beneath the Grigne peaks, is led by pine and oak among tree species, with grass adding to seasonal totals from the surrounding Lombardia land. Streets close to open ground typically see a different mix than the denser centre, particularly once the main tree pollen peak has eased off.
From an early pine and eucalyptus start, Lecco moves into a pine and oak peak before grass extends the season into early summer, with the winter-to-summer stretch from January to August covering the year's exposure in this part of Lombardia. a typically dry summer means late-season exposure stays low, a pattern shaped in part by the town's position on the eastern shore of Lake Como beneath the Grigne peaks.

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