Local Environmental Conditions
Sunrise Manor's suburban setting in the Las Vegas Valley means introduced olive, mulberry, and cypress trees planted across parks and residential streets are the main allergenic pollen sources, with exposure varying between these irrigated green areas and the more arid urban core. Surrounding Mojave Desert scrub and grassland contribute seasonal shrub and grass pollen under prevailing winds across the valley.
Sunrise Manor's pollen season in the Las Vegas Valley is dominated by introduced olive and mulberry from February through April, producing intense early-season tree pollen. Native Mojave Desert species contribute seasonal shrub pollen, while introduced grasses add spring exposure. The long, hot, dry summer largely suppresses mid-season pollen, with exposure almost entirely from irrigated urban plantings in the enclosed desert basin setting.

How often is the Sunrise Manor pollen forecast updated?

Does pollen in Sunrise Manor 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 Sunrise Manor 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 Sunrise Manor, 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. |
