Local Environmental Conditions
The area around this location in Genoa is mostly farmland, with a good deal of open grassland and some built-up land. A nearby park adds mown lawns and planted trees to the local pollen mix. In the immediate area, open grassland and farmland add grass and weed pollen. Field margins, fallow strips and pasture around the farmland add further grass and weed pollen.
Through the seasons, grass pollen dominates, building from mid-spring to a peak around early summer and lasting until late summer. A smaller weed peak follows from early summer into early fall, from plants on verges and waste ground. Here, temperatures range from a few degrees below freezing in the coldest month to around 25°C in the warmest, with most rain falling in the warmer months.

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

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. |
