Local Environmental Conditions
Pamplona's parks and the Arga River corridor feature oak, plane, and poplar as the main tree pollen sources, with exposure varying between green areas and the more built-up city centre. Surrounding Navarrese farmland and the Pyrenean foothills contribute substantial grass and tree pollen, while the sub-Atlantic climate means more frequent rainfall than in drier parts of Spain, providing regular interruptions to exposure.
Pamplona's pollen season runs from January through July, opening with hazel and alder from January before oak and plane peak through April and May. Grass pollen peaks through June and July. The sub-Atlantic Navarrese climate means more frequent rainfall than in drier parts of Spain provides regular interruptions, while the Arga River valley and the Pyrenean foothills channel airflows and contribute substantial tree and grass pollen throughout the season.

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