Local Environmental Conditions
Woodland and open grassland share the area around the heart of Whitchurch Hampshire, plus some built-up land. The surrounding woodland makes trees an important local pollen source. Beyond the trees, grasses matter a great deal, and plantain is the main weed source. Roadside verges and patches of open ground provide further room for grasses and weeds.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer and keep pollen in the air into late summer. Later, plantain keeps weed pollen in the air from late spring into late summer. By early winter, as temperatures fall to around 5°C, pollen levels are low again.

How often is the Whitchurch Hampshire pollen forecast updated?

Does pollen in Whitchurch Hampshire 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 Whitchurch Hampshire 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 Whitchurch Hampshire, 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 pollen scores represent risk levels, not direct pollen measurements. Higher scores indicate higher risk.
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. |
