Local Environmental Conditions
Around 76% of the area near the center of Guadalajara is built-up land, with some woodland. Close to the Henares River, riverside trees such as poplar add to local tree pollen. The key allergenic tree nearby is poplar. Weed pollen comes mainly from pigweed. In the immediate area, street trees, parks and lawns are the main sources in the built-up parts.
Tree pollen peaks in late winter, when the weather warms to around 5°C and poplar is in full flower. The season closes with pigweed from early summer into early fall. Rain is heaviest in fall, often giving short breaks from high pollen levels. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Guadalajara pollen forecast updated?

Does pollen in Guadalajara 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 Guadalajara 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 Guadalajara, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
