Local Environmental Conditions
The landscape around this site in Aguanga is heavily wooded. A nearby park adds mown lawns and planted trees to the local pollen mix. Among allergenic trees nearby, oak is the main source. Beyond the trees, grasses matter a great deal, and pigweed and ragweed are the main weed sources.
Oak leads the season in mid-spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Grass pollen follows, peaking in late spring and easing off by early fall. The season closes with pigweed and ragweed from early summer into early fall. Rain is heaviest in spring, often giving short breaks from high pollen levels.

How often is the Aguanga pollen forecast updated?

Does pollen in Aguanga 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 Aguanga 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 Aguanga, 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. |
