Local Environmental Conditions
Melo commands the Cerro Largo department of northeastern Uruguay near the Brazilian border as the region's main city, where eucalyptus, native pampa grasses, and introduced urban trees native pampa grasses and introduced urban trees dominate locally, and grass from nearby Cerro Largo farmland extends exposure through the spring and summer peak. The wet season that follows regularly interrupts pollen counts.
Melo sees its clearest pollen signal from October to December, driven by native pampa grasses and introduced urban trees during the Southern Hemisphere spring and early summer. Once summer rains set in, pollen counts usually drop off noticeably.

Does pollen in Melo 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 Melo 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 Melo, 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. |
