Local Environmental Conditions
The landscape around this location in Cangas de Onís is largely bare ground. With much of the immediate area made up of bare ground, local pollen production is limited, though pollen can still drift in from surrounding land. Allergenic trees in the wider area include oak. Grasses growing in the surroundings are the main non-tree source of pollen.
Oak leads the season in late spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in midsummer and fading by early fall. A smaller weed peak follows from early summer into early fall. Rain is heaviest in fall, often giving short breaks from high pollen levels. By late fall, as temperatures fall to around 5°C, pollen levels are low again.

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