Local Environmental Conditions
The heart of Cajazeiras is surrounded mainly by built-up land. A lake or pond nearby means lakeside vegetation is part of the local pollen picture. In the immediate area, street trees, gardens and lawns supply most pollen in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
With warm weather all year, between about 25°C and 30°C, pollen is present in most months rather than in one short season. Levels tend to be highest in the drier months around August to October. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. In warm, humid weather from midsummer into mid-fall, mold spores add to the mix, especially after rain.

Does pollen in Cajazeiras 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 Cajazeiras 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 Cajazeiras, 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.

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. |
