Local Environmental Conditions
Around 41% of the area near this location in Saint Augustine is built-up land, with a good deal of open water and some woodland. A nearby park adds mown lawns and planted trees to the local pollen mix. Of the trees nearby, oak and juniper are the ones that matter most for allergies. Beyond the trees, grasses matter a great deal, and ragweed and pellitory are the main weed sources.
Oak and juniper lead the season in early spring, as temperatures climb to around 20°C, and tree pollen reaches its peak. Grass pollen follows, peaking in mid-spring and easing off by mid-fall. Ragweed and pellitory bring a final peak from late summer into mid-fall. Warm, damp weather from early summer into early winter also raises mold spore levels.

Does pollen in Saint Augustine 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 Saint Augustine 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 Saint Augustine, 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.

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. |
