Local Environmental Conditions
Most of the area around the heart of Las Piedras is built-up land, with some open grassland and woodland. Around here, open grassland adds grass and weed pollen; street trees, gardens and lawns supply most pollen in the built-up parts. Roadside verges and patches of open ground provide further room for grasses and weeds.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Rain is heaviest in fall, often giving short breaks from high pollen levels.

Does pollen in Las Piedras 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 Las Piedras 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 Las Piedras, 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. |
