Local Environmental Conditions
Bay Hill sits in a varied landscape of woodland, built-up land and open grassland. Along running water nearby, trees, shrubs and reeds grow in the damper ground and add their own pollen. Oak stands out as the main allergenic tree nearby. Grasses also feature strongly, alongside pigweed among the weeds.
Tree pollen peaks in early spring, when the weather warms to around 20°C and oak is in full flower. Then come the grasses, strongest in early spring and fading by mid-fall. The season closes with pigweed from early summer into early fall. Mold spores join in from midsummer into early winter, when damp, warm spells let them thrive.

When is pollen season in Bay Hill?
How often is the Bay Hill pollen forecast updated?
The Bay Hill pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Bay Hill 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 Bay Hill 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 Bay Hill, 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.
Airmine’s atmospheric monitoring platform was developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team, using satellite and Earth observation technologies to improve emissions monitoring.
Understanding the Scale
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. |
