Local Environmental Conditions
La Línea de la Concepción's seafront green spaces and the Bay of Gibraltar waterfront feature olive, pine, and eucalyptus as the main pollen sources, with the Alcornocales Natural Park cork oak woodland contributing substantially from the northwest. Strong Strait of Gibraltar onshore winds frequently disperse pollen, while surrounding Andalusian farmland extends additional grass and tree pollen across the border city.
La Línea de la Concepción's Strait of Gibraltar position means strong onshore winds frequently interrupt the pollen season. Olive, cypress, and pine open the season from January, with cypress contributing through spring, before grass from surrounding Andalusian farmland peaks through April and May. Mugwort and nettle extend exposure into September, while cross-strait pollen from Morocco adds distinctive exposure throughout spring.

Does pollen in La Línea de la Concepción 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 La Línea de la Concepción 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 La Línea de la Concepción, 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. |
