Local Environmental Conditions
Set on flat farmland along the Arkansas River, Pine Bluff's landscape is defined by riverside cottonwood alongside bottomland hardwood and cotton and soybean fields, the main contributors to seasonal pollen exposure. Individual yards and gardens around Pine Bluff can still vary somewhat from this general pattern. Residents who spend time outdoors around Pine Bluff typically notice the shift as each season turns over.
In Pine Bluff, pollen season begins with maple and elm starting in March with oak taking the lead through April. Peak grass pollen arrives in May and June, and ragweed extends the season into September. A humid continental climate drives a sharp spring tree peak and an equally distinct late-summer ragweed run.

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 Pine Bluff 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 Pine Bluff, 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 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
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. |
