Local Environmental Conditions
The heart of San Fernando is densely built up. Common allergenic trees nearby include olive. Grasses are a major source, with pigweed adding to the weed pollen load. In the immediate area, planted trees and mown lawns are the main sources in the built-up parts. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Olive leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into mid-fall. Later, pigweed keeps weed pollen in the air from early summer into early fall. Spring is the wettest time of year, and heavy showers can bring short breaks in pollen.

Does pollen in San Fernando 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 San Fernando 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 San Fernando, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
