Local Environmental Conditions
This part of Twentynine Palms is mostly scrubland, with some bare ground. Common allergenic trees nearby include oak and juniper. Grasses and weeds such as ragweed and pigweed round out the local mix. Locally, scrubland contributes pollen from shrubs, grasses and herbs. Roadside verges and patches of open ground provide further room for grasses and weeds.
Juniper opens the pollen season from late winter into early spring. Tree pollen then builds as oak flowers, peaking around mid-spring. Then come the grasses, with a peak around late spring that eases by midsummer. Later in the year, ragweed adds weed pollen from late summer into mid-fall. Locally, winters average around 10°C and summers around 30°C, and rain is scarce.

Are pollen levels in Twentynine Palms 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 Twentynine Palms, 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. |
