Local Environmental Conditions
Around 69% of the area near this part of Sonora is woodland, with a good deal of built-up land. A stream or river nearby means riverside vegetation is part of the local pollen picture. The allergenic tree mix nearby includes oak. Grasses are also a significant pollen source here. Street trees, private gardens and mown lawns add to local pollen in the more built-up surroundings.
The pollen year opens with oak, peaking around mid-spring. From mid-spring, grass pollen rises to a peak around early summer before easing off by late summer. The season closes with a lower weed peak from early summer into early fall, mostly from roadside and field-edge plants. Winters average around freezing and summers around 25°C, with most rain falling in the cooler months.

Does pollen in Sonora 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 Sonora 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 Sonora, 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.

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. |
