Local Environmental Conditions
Conway's Arkansas River valley setting features oak, sweetgum, and elm as the main tree pollen sources, with exposure varying between the wooded residential neighborhoods on the hilltops and the more built-up commercial corridors along Dave Ward Drive. Hendrix College campus and the Toad Suck Ferry Recreation Area provide locally significant green space, while the flat Arkansas River valley allows grass pollen from surrounding farmland to disperse widely.
Conway's Central Arkansas setting produces a season opening in late January with cedar and elm before oak peaks through March and April. Grass from surrounding Arkansas farmland peaks through May and June before mugwort and nettle extend exposure into September. The Arkansas River valley channels airflows, while the warm Mid-South climate advances the season compared to more northern US cities throughout.

How often is the Conway pollen forecast updated?

Does pollen in Conway 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 Conway 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 Conway, 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. |
