Local Environmental Conditions
Tucuruí commands the Tocantins River in the Pará Amazon lowlands at the enormous Tucuruí hydroelectric reservoir, where native Amazon forest trees, reservoir shoreline vegetation, and secondary forest 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 this important Pará hydropower city.
Tucuruí produces pollen year-round given its equatorial setting, with native Amazon forest trees and reservoir shoreline vegetation pollen present throughout; the wet season from November to May brings the most frequent rainfall interruptions to an otherwise steady pollen presence.

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