Local Environmental Conditions
Around Hunstanton, oak and plane are the dominant species behind local tree pollen, with counts higher near parks than in the centre. Grass pollen from surrounding Norfolk fields is significant through the summer months, carried in by prevailing westerlies. This mix of urban and rural influence gives Hunstanton a fairly typical pollen pattern for the wider region.
Want to know what triggers spring allergies in Hunstanton? Start with oak, then plane. On top of that, grass pollen runs May to September and tends to hit hardest in June and July. You'll usually see oak pollen from around April through May, then plane carries on from April until June. Useful to know if you tend to feel it every spring.

Does pollen in Hunstanton 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 Hunstanton 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 Hunstanton, 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. |
