Local Environmental Conditions
Around Deal, oak and plane are the dominant species behind local tree pollen, with counts higher near parks than in the centre. The wider Kent countryside supplies additional tree and grass pollen, particularly when moist Atlantic fronts carry it toward the built-up area. Overall exposure follows the broader regional trend, moderated somewhat by the town's parks and gardens.
Want to know what triggers spring allergies in Deal? Start with oak, then plane. Grass pollen then stretches from May into September, with the worst of it typically landing in June and July. Expect oak pollen roughly from April to May, while plane follows on from April to June. Not a bad idea to stock up on antihistamines before it all kicks off.

How often is the Deal pollen forecast updated?

Does pollen in Deal 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 Deal 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 Deal, 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. |
