Local Environmental Conditions
Valladolid's parks and the Pisuerga River corridor feature pine, oak, and poplar as the main tree pollen sources, with exposure varying between 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 semi-arid continental climate and low summer rainfall concentrate pollen dispersal during spring.
Valladolid's pollen season runs from February through June, opening with pine and oak tree pollen in late winter before grass pollen from surrounding Castilian cereal farmland peaks through May and June. The semi-arid continental climate and low summer rainfall concentrate pollen dispersal during spring, while the Pisuerga River valley channels airflows and concentrates pollen under calm conditions during the intense spring peak period.

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