Local Environmental Conditions
Ananindeua's tropical urban setting adjacent to Belém features native rainforest species including açaí palm and mango as the main tree pollen sources, with exposure varying between green areas and the densely built city centre. Surrounding Amazon lowland vegetation and the Guamá River corridor contribute substantial year-round pollen, with frequent tropical rainfall periodically suppressing dispersal.
Ananindeua's pollen season runs year-round in the wet equatorial climate adjacent to Belém, with native rainforest species including açaí palm and mango contributing continuously. Exposure is highest during the drier months from July to November, while the intense wet season from December to June brings near-daily rainfall that regularly suppresses pollen dispersal across the Amazon lowland setting.

How often is the Ananindeua pollen forecast updated?
The Ananindeua pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Ananindeua 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 Ananindeua 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 Ananindeua, 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. |
