Local Environmental Conditions
Here, barely 200-300 meters away, hazel and willow thrive along the damp bank, both prolific early wind-pollinators. This area, a stone's throw away, around 100-200m, has oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. This area, hardly 150 meters distant, has well-kept lawns and ornamental trees in this park add their share of grass and ragweed pollen.
The waterside hazel and willow are consistently first to release pollen each year, climbing steadily from late winter into March. Once hazel fades, oak and birch in the woods carry the season forward, peaking in the heart of spring, generally April into May. Late spring brings rising grass pollen that crests in June, then gives way to ragweed, which drives the season's second major surge from mid-August into October.

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