Local Environmental Conditions
Palencia's parks and the Carrión River corridor feature poplar, oak, and ash as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Castilian cereal farmland and the Meseta plateau contribute substantial grass and crop pollen, while the Carrión valley channels airflows and the cold, semi-arid continental climate concentrates pollen dispersal during the short spring season.
Palencia's pollen season opens in February with hazel and poplar before oak peaks through April. Grass from surrounding Castilian cereal farmland peaks strongly through May and June. The Carrión valley channels airflows, while the cold, semi-arid continental climate concentrates pollen during the short but intense spring season and the summer heat ends the season abruptly by July.

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