Local Environmental Conditions
Jerez de la Frontera's Parque González Hontoria and the Guadalete River corridor feature olive, pine, and eucalyptus as the main tree pollen sources, with exposure varying between these green areas and the more built-up city centre. Surrounding Andalusian farmland and the extensive vineyards of the sherry triangle contribute substantial grass and crop pollen, while the hot, dry Mediterranean climate concentrates pollen during spring.
Jerez de la Frontera's pollen season opens in January with olive and pine before grass from surrounding Andalusian farmland and sherry vineyards peaks through April and May. The hot, dry Mediterranean summer ends the season abruptly, while the flat Atlantic-facing Cádiz plain allows pollen to disperse widely under prevailing southwesterly winds throughout the spring season.

Does pollen in Jerez de la Frontera 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 Jerez de la Frontera 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 Jerez de la Frontera, 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 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. |
