Local Environmental Conditions
Salto in Uruguay occupies the Uruguay River as the country's second largest city opposite Argentina, where eucalyptus, native riverside gallery forest, and introduced urban trees eucalyptus and introduced urban trees account for most of the pollen here, and grass from neighbouring Salto land contributes through the warmer months. Wetter weather later on regularly clears the air.
In Salto, eucalyptus and introduced urban trees peaks from October through December as the Southern Hemisphere spring progresses into summer. Warmer, stiller days during the peak tend to bring the highest counts.

How often is the Salto pollen forecast updated?

Does pollen in Salto 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 Salto 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 Salto, 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. |
