Local Environmental Conditions
Montevideo stretches along the Río de la Plata estuary, where eucalyptus, native coastal scrub, and introduced urban boulevard trees native coastal scrub and introduced urban boulevard trees account for most of the pollen here, and grass from nearby Montevideo land contributes through the warmer months. Wetter weather later on regularly clears the air.
Pollen exposure in Montevideo builds through October and December, led by native coastal scrub and introduced urban boulevard trees, as spring gives way to summer in the Southern Hemisphere. Surrounding farmland adds further grass pollen through the peak weeks.

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