Local Environmental Conditions
The center of Cruzeiro is densely built up, with some woodland. With the Sul River nearby, riverside vegetation along its banks contributes to the local mix. Around here, street trees, parks and lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Flowering trees bring the first pollen of the year in early spring. Then come the grasses, strongest in early spring and fading by mid-fall. A smaller weed peak follows from early summer into early fall. In warm, humid weather from early summer into mid-fall, mold spores add to the mix, especially after rain.

How often is the Cruzeiro pollen forecast updated?

Does pollen in Cruzeiro 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 Cruzeiro 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 Cruzeiro, 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. |
