Local Environmental Conditions
Around Shamrock Golf Course, nearby, within easy reach, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. Located within the neighborhood's edge, this area has well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen. The broader area tends to mirror this pattern, with only minor local variation.
For Shamrock Golf Course, the waterside hazel and willow are consistently first to release pollen each year, usually the first pollen source active, peaking sometime in February or March. Grass pollen climbs toward a June peak, before ragweed's late-summer surge carries the season into October. Regional pollen monitoring generally reflects this same pattern across nearby areas.

Does pollen in Corcoran 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 Corcoran 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 Corcoran, 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. |
