Local Environmental Conditions
Wellington's Palm Beach County equestrian community setting features live oak, melaleuca, and sabal palm as the main tree pollen sources alongside distinctive equestrian pasture grasses. Exposure varies between the greener equestrian and residential areas and the more built-up commercial corridors along SR 7, while the flat South Florida landscape allows pollen to disperse widely and the extensive equestrian community grass pastures contribute locally significant grass pollen throughout summer.
Wellington's Palm Beach County suburban setting produces an extended subtropical pollen season opening in December with melaleuca and oak before grass from surrounding Palm Beach County land peaks through February and March. Mugwort and nettle extend exposure through autumn, while the flat South Florida landscape allows pollen to disperse widely and the warm subtropical climate supports near year-round production throughout.

How often is the Wellington pollen forecast updated?
The Wellington pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Wellington 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 Wellington 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 Wellington, 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. |
