Local Environmental Conditions
Around 39% of the area near the heart of Jackson is open grassland, with a good deal of built-up land and some woodland. With a stream or river close by, riverside vegetation contributes to the local mix. The key allergenic tree nearby is oak. Grasses are also a significant pollen source here.
Across the year, tree pollen comes first, with oak in flower through spring. The grass season runs from mid-spring to midsummer, with its high point around late spring. A smaller weed peak follows from early summer into early fall, from plants on verges and waste ground. Locally, winters average around 10°C and summers around 25°C, with most rain falling in the cooler months.

Does pollen in Jackson 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 Jackson 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 Jackson, 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. |
