Local Environmental Conditions
The heart of Città di Castello is surrounded mainly by built-up land, which covers around 51% of the nearby area, with some woodland and open grassland. The surrounding woodland makes trees an important local pollen source. There is plenty of grass pollen here too. Around here, planted trees and mown lawns are the main sources in the built-up parts.
Tree pollen comes first, peaking in mid-spring. Grasses take over in late spring, with temperatures around 15°C, and their pollen lingers into early fall. A smaller weed peak follows from early summer into early fall. By early winter, as temperatures fall to around 5°C, pollen levels are low again. Weather shapes each of these periods: dry, windy spells drive levels up, and showers wash pollen out of the air.

How often is the Città di Castello pollen forecast updated?

Does pollen in Città di Castello 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 Città di Castello 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 Città di Castello, 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. |
