Local Environmental Conditions
This location in Loma Rica is surrounded mainly by woodland, with a good deal of open grassland. The surrounding woodland makes trees an important local pollen source. Grass pollen adds noticeably to the overall load. Grasses along roadsides, verges and open ground also add to the overall pollen load. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Tree pollen comes first, peaking in early spring. Then come the grasses, strongest in late spring and fading by early fall. Weeds on open ground add a smaller late peak from early summer into early fall. Rain is heaviest in winter, often giving short breaks from high pollen levels. Within each of these periods, warm, dry and windy days push levels higher, while rain clears the air.

Does pollen in Loma Rica 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 Loma Rica 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 Loma Rica, 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.

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. |
