Local Environmental Conditions
Bald cypress and water tupelo line the water's edge, common trees of this area's blackwater rivers; this sits nearby. Forest where longleaf pine and live oak make up much of the canopy, driving local spring pollen counts; this sits in the surrounding area. Parkland with regularly mown grass and planted trees, both sources of grass and ragweed pollen, within easy reach.
January is the coldest month here at around 13°C, warming to about 28°C by July, and the bulk of this area's 1114 mm annual rainfall comes during the warmer months, around July. Look for pollen activity to build from around February, as this area's temperatures climb out of their January low.

Does pollen in High Springs 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 High Springs 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 High Springs, 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. |
