Local Environmental Conditions
Almost 100% of the area near this location in Death Valley is bare ground. With much of the immediate area made up of bare ground, local pollen production is limited, though pollen can still drift in from surrounding land. Pigweed growing in the surroundings is the main non-tree source of pollen.
Pigweed brings a later peak from early summer into early fall. Temperatures range from around 10°C in the coldest month to around 35°C in the warmest, and rain is scarce. Actual levels on any given day depend on the weather, with dry, breezy days the worst and wet days the mildest.

How often is the Death Valley pollen forecast updated?
The Death Valley pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Death Valley 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 Death Valley 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 Death Valley, 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. |
