Local Environmental Conditions
Cádiz' exposed Atlantic peninsula position means strong onshore winds frequently disperse pollen across the historic port city. Olive, pine, and introduced trees feature in parks and along the seafront corridor, with exposure varying between these green areas and the densely built city centre. Surrounding Andalusian farmland and the Bay of Cádiz wetlands contribute grass and reed pollen throughout the season.
Cádiz' pollen season opens in January with olive and pine, with the exposed Atlantic peninsula position meaning strong onshore winds frequently interrupt dispersal. Grass from surrounding Andalusian farmland and Bay of Cádiz wetlands peaks through April and May. Reed pollen from the wetlands adds locally distinctive exposure, while the Atlantic onshore winds make Cádiz one of the more wind-dispersed pollen environments in Spain.

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