Local Environmental Conditions
Around 99% of the area near the heart of Lesley is woodland. Around here, the woodland makes trees an important source. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen. Much of the pollen in dense woodland is released high in the canopy, where the wind carries it easily.
Flowering trees bring the first pollen of the year in early spring. Grasses take over in late spring, with temperatures around 20°C, and their pollen lingers into early fall. Winter is the wettest time of year, and heavy showers can bring short breaks in pollen. Weather shapes each of these periods: dry, windy spells drive levels up, and showers wash pollen out of the air.

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