Local Environmental Conditions
This part of Ahwahnee is surrounded mainly by woodland, which covers around 93% of the nearby area. Along a watercourse nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Among allergenic trees nearby, oak is the main source. Grasses are a major source, with plantain adding to the weed pollen load.
Through the seasons, tree pollen comes first, with oak in flower through spring. Grasses take over from mid-spring, with the highest levels around late spring and pollen lingering until midsummer. Later in the year, plantain adds weed pollen from mid-spring into midsummer. Winters average around 5°C and summers around 30°C, with most rain falling in the cooler months.

Does pollen in Ahwahnee 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 Ahwahnee 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 Ahwahnee, 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.

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. |
