Local Environmental Conditions
Chiclana de la Frontera's parks and the Iro River and Sancti Petri salt marsh corridor feature pine, eucalyptus, and introduced trees as the main pollen sources alongside halophytic coastal vegetation, with exposure varying between these areas and the more built-up city centre. Surrounding Cádiz farmland and coastal wetlands contribute grass and reed pollen, while Atlantic onshore winds frequently disperse pollen.
Chiclana de la Frontera's pollen season opens in January with pine and olive before grass from surrounding Cádiz farmland and coastal wetlands peaks through April and May. Reed pollen from the Sancti Petri salt marshes is a locally distinctive source. Strong Atlantic onshore winds frequently disperse pollen, while the season ends abruptly with the summer heat by June.

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. |
