Local Environmental Conditions
This mix of urban and rural influence gives Whitstable a fairly typical pollen pattern for the wider region. That's on top of oak and birch, which are the main local tree pollen sources around Whitstable's parks and quieter streets. Fields and hedgerows just outside town push grass pollen counts up noticeably once southwesterly winds set in.
For Whitstable, the season kicks off with oak and then hands things over to birch. Oak pollen typically runs from April to May, while birch follows on from March to May. Grass season overlaps a lot of this too, running May through September and peaking mid-summer. Good to know if you're planning anything outdoors that time of year.

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