Local Environmental Conditions
This area, in the vicinity, has a stretch of hazel and willow lines the water, feeding some of spring's earliest pollen. Local microclimate and soil conditions can push these figures slightly higher or lower. The broader area tends to mirror this pattern, with only minor local variation. Seasonal timing here generally tracks the wider region, give or take a week or so.
The waterside hazel and willow are consistently first to release pollen each year, getting an early start, typically cresting between February and March. Grass pollen climbs toward a June peak, and then ragweed picks up the slack, running from mid-August through October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

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