Local Environmental Conditions
Woodland makes up around 41% of the area near this part of Mammoth Lakes, with a good deal of open grassland and some open water. Allergenic trees nearby include poplar, willow and juniper. Grasses also feature strongly, alongside mugwort among the weeds. Grasses along roadsides, verges and open ground also add to the overall pollen load.
Poplar, willow and juniper lead the season in late spring, as temperatures climb to around 5°C, and tree pollen reaches its peak. Then come the grasses, strongest in midsummer and fading by late summer. The season closes with mugwort through summer. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. By mid-fall, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Mammoth Lakes pollen forecast updated?

Does pollen in Mammoth Lakes 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 Mammoth Lakes 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 Mammoth Lakes, 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. |
