Local Environmental Conditions
The area around the heart of Lenwood is mostly bare ground, with a good deal of built-up land. Lawns and planted trees in a nearby park add to local grass and tree pollen. With much of the immediate area made up of bare ground, local pollen production is limited, though pollen can still drift in from surrounding land.
Trees are the first to release pollen, with a peak around early spring. Grass pollen builds from mid-spring, peaks around late spring and stays noticeable until midsummer. Weeds on open ground add a smaller late peak from early summer into early fall. Locally, temperatures range from around 5°C in the coldest month to around 30°C in the warmest, with most rain falling in the cooler months.

How often is the Lenwood pollen forecast updated?

Does pollen in Lenwood 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 Lenwood 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 Lenwood, 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 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. |
