Local Environmental Conditions
Paysandú commands the Uruguay River in northwestern Uruguay as the country's third largest city opposite Argentina, where eucalyptus, native riverside gallery forest, and introduced urban trees eucalyptus and native riverside gallery forest dominate locally, and grass from nearby Paysandú farmland extends exposure through the spring and summer peak. The wet season that follows regularly interrupts pollen counts.
Pollen exposure in Paysandú builds through October and December, led by eucalyptus and native riverside gallery forest, as spring gives way to summer in the Southern Hemisphere. Surrounding farmland adds further grass pollen through the peak weeks.

Does pollen in Paysandú 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 Paysandú 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 Paysandú, 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 exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen exposure is expected to be at or near its highest levels. |
