Local Environmental Conditions
Around 59% of the area near the heart of Picos is built-up land, with some woodland and open grassland. Around here, planted trees and mown lawns are the main sources in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds. Pollen also travels on the wind, so vegetation in the wider surroundings adds to local levels as well.
With warm weather all year, between about 25°C and 30°C, pollen is present in most months rather than in one short season. The drier stretch around July to September usually brings the most pollen. During the rainy season, frequent heavy downpours wash much of the pollen out of the air. In warm, humid weather from midsummer into early fall, mold spores add to the mix, especially after rain.

How often is the Picos pollen forecast updated?

Does pollen in Picos 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 Picos 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 Picos, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
