Local Environmental Conditions
Avilés' coastal parks and the Avilés estuary corridor feature oak, birch, and eucalyptus as the main tree pollen sources, with exposure varying between these green areas and the more built-up industrial city centre. Surrounding Asturian woodland and farmland contribute substantial tree and grass pollen, while the Atlantic-facing Cantabrian position means very frequent rainfall provides regular interruptions throughout the season.
Avilés' pollen season opens in January with hazel and alder before birch and oak peak through April and May. Grass peaks through June and July. The very wet Atlantic Cantabrian climate means Avilés is one of the most frequently interrupted pollen seasons in Spain, with the Avilés estuary position adding additional onshore wind influence throughout the season.

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