Local Environmental Conditions
The center of Genoa is surrounded mainly by built-up land, which covers around 81% of the nearby area. Allergenic trees nearby include ash, oak and elm. Grasses and weeds such as pigweed and pellitory round out the local mix. Around here, planted trees and mown lawns are the main sources in the built-up parts.
The pollen year starts in late winter, when elm flowers. Tree pollen peaks in early spring, when the weather warms to around 10°C and ash and oak are in full flower. Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. Pigweed and pellitory bring a final peak from early summer into early fall. By early winter, pollen levels are low again.

How often is the Genoa pollen forecast updated?

Does pollen in Genoa 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 Genoa 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 Genoa, 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. |
