Local Environmental Conditions
The landscape around this location in Marin City is mostly open water. Allergenic trees in the wider area include hazel, oak and cypress. Grasses, mugwort and plantain growing in the surroundings are the main non-tree sources of 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.

How often is the Marin City pollen forecast updated?

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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
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. |
