Local Environmental Conditions
Wigwam Motel occupies a roadside motel with rooms shaped like concrete teepees along old Route 66, and its plant life mirrors the rest of Holbrook, so seasonal pollen sources here match the broader regional pattern. As with most sublevel sites, local landscaping can shift counts slightly from the citywide average.
As a landmark within Holbrook, Wigwam Motel follows the same seasonal pollen curve, opening with palo verde and mesquite from January before mulberry peaks during February. Grass pollen then peaks through March and April, and monsoon moisture from July through September brings a brief second wave of grass and weed pollen. Dry desert air lets pollen travel widely once released, with the spring peak the most intense stretch, which shapes conditions at Wigwam Motel much as it does elsewhere in Holbrook.

Does pollen in Holbrook 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 Holbrook 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 Holbrook, 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. |
