Local Environmental Conditions
Set on flat farmland in south-central Nebraska, Hastings's landscape is defined by corn and soybean fields alongside prairie grasses and riverside cottonwood, the main contributors to seasonal pollen exposure. None of this is unusual for a town with Hastings's particular mix of terrain and plant life. Microclimates within the area can shift the timing slightly from one neighborhood to the next.
In Hastings, pollen season begins with elm and cottonwood starting in March with ash following close behind through April. Peak grass pollen arrives in May and June, and a strong ragweed peak follows in late summer into September. Surrounding farmland is a major contributor to both the spring grass peak and the late-summer ragweed season.

How often is the Hastings pollen forecast updated?

Does pollen in Hastings 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 Hastings 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 Hastings, 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. |
