Local Environmental Conditions
The area around this site in Marin City is a mix of woodland and open water, plus some open grassland. Hazel, oak and cypress are among the allergenic trees nearby. Grass pollen is significant here, and mugwort and plantain contribute weed pollen. Mugwort is unusually common here compared with most other locations, making it a particularly important local pollen source.
First to flower are hazel and cypress, in late winter. Tree pollen peaks in mid-spring, when the weather warms to around 10°C and oak is in full flower. Then come the grasses, strongest in early summer and fading by early fall. Mugwort and plantain bring the strongest peak of the year through summer. Rain is heaviest in winter, often giving short breaks from high pollen levels.

Does pollen in Marin City 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 Marin City 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 Marin City, 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.

| 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. |
