Local Environmental Conditions
Open water and woodland share the area around this site in Siesta Key, plus some built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. Oak is the most prominent allergenic tree nearby, with pecan and mulberry also present. Beyond the trees, grasses matter a great deal, and pigweed and ragweed are the main weed sources.
Oak, pecan and mulberry lead the season in early spring, as temperatures climb to around 20°C, and tree pollen reaches its peak. Grass pollen follows, peaking in early spring and easing off by late fall. The season closes with pigweed and ragweed from early summer into early fall. Warm, damp weather from early summer into late winter also raises mold spore levels.

Does pollen in Siesta Key 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 Siesta Key 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 Siesta Key, 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.

The 0–100 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
