Local Environmental Conditions
The landscape around the center of Itu is densely built up. Close to the Piracicaba River, riverside vegetation adds to local tree pollen. Locally, planted trees and mown lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
Grass pollen follows, peaking in early spring and easing off by mid-fall. A smaller weed peak follows from early summer into early fall. Warm, damp weather from early summer into mid-fall also raises mold spore levels. Day to day, sunshine and wind lift the counts, while a spell of rain can bring them down sharply.

How often is the Itu pollen forecast updated?

Does pollen in Itu 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 Itu 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 Itu, 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. |
