Local Environmental Conditions
Val di Fiemme occupies the Fiemme Valley in the Trentino Dolomites, where spruce, larch, and mountain pine spruce and larch provide most of the tree pollen, and grass from Trentino-Alto Adige farmland contributes across spring. The Mediterranean summer that follows keeps pollen in check for the remainder of the year.
Val di Fiemme follows a classic Mediterranean pattern: spruce and larch first, then grass over the spring weeks, then an abrupt end as summer heat and drought take hold, running April to September overall. Mugwort can extend the season briefly into early autumn in some years.

How often is the Val di Fiemme pollen forecast updated?

Does pollen in Val di Fiemme 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 Val di Fiemme 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 Val di Fiemme, 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 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. |
