Local Environmental Conditions
Óbidos commands the Amazon River at its narrowest navigable point in western Pará as a historic colonial fort city, where native Amazon forest trees, várzea floodplain vegetation, and the Amazon River corridor riparian species are the main pollen sources. Year-round tropical pollen production means no distinct seasonal boundaries, while frequent Amazon rainfall provides regular interruptions and the wet season from November to May brings the most sustained breaks throughout.
Óbidos's tropical climate keeps native Amazon forest trees and the Amazon River corridor riparian species pollen in the air year-round, with the clearest breaks coming during the wet season from November to May when rainfall is most frequent.

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